Top 5 Essential Gunsmithing Tools
How to Become a Gunsmith?
How to Remove Rust From Gun
CRATEX Products for Gunsmithing
CRATEX Abrasives and other CRATEX products are perfect tools for gunsmithing and their place in workshops of many gunsmiths has been well-earned over the years.
CRATEX rubber bonded abrasives are made of high-quality silicon carbide and are perfect for operations like: removing rust from old firearms, removing trigger serrations, removing stretches, rounding edges, cleaning up worn or damaged pistol and rifle markings and engravings, polishing flash pan, bolts and feed ramps, smoothing surface and getting almost mirror finish, jeweling a rifle bolt or pistol barrel, etc.
CRATEX abrasives come in four standard grit textures which differ in color: Course (green), Medium (dark brown), Fine (reddish brown) and Extra Fine (grey green). However, there is also the possibility to modify standard shapes and grits and get a modified abrasive tool that fits your needs much better.
Below you’ll find some of the CRATEX products widely used as gunsmith tools and equipment.
1. CRATEX Small Wheels
CRATEX small abrasive wheels are used for fine metal polishing, smoothing, deburring and many other uses in customizing and modifying guns. Small grinding wheels can be used for after hammer spur removal to create a nice, even surface on the back of the hammer. After that, sanding abrasives can be used to remove previous grinding marks and for contouring, and at the end, progressively finer grit wheels for polishing. Of course, small wheels can be used for polishing other parts of the firearm as well, like the trigger.
2. MX Abrasives
CRATEX MX abrasives are cotton-fiber aluminum-oxide laminate-bond products, which are much more aggressive than CRATEX rubber-bond abrasives. Their most prominent characteristics are the ability to hold shape and cutting action, so they are used for more aggressive prep work. MX abrasives are perfect for removing tooling marks left on parts from milling.
Recommendation: Use MX cone-shaped abrasives to remove marks and then use a fine rubber-cone for a smooth finish.
3. CRATEX Points & Cones
CRATEX abrasive points & cones are shaped and ready to use for polishing even hard-to-reach delicate firearm parts and angles. Easily carved, they are perfect to get into corners and rails. They can be used on a grinding tools for creating an even surface after metal removal jobs, like removing a revolver hammer spur, for working on the receiver to make the new bolt handle fit properly, for removing trigger serrations, for feed ramp work, for flare/fair ejection port work, throating the barrel, etc.
@tacticalchipmunk Once again it's @cratexsandiego products to the rescue. This #glock had all kinds of #damage where a previous coating had been scraped off. Well, with the help of a file, a knife, and a few #cratex points, it was smoothed out and prepared for #cerakote
Recommended: CRATEX Kit No. 777 – Small wheels, points and mandrels
This kit contains a total of 80 different tapered edge and straight wheels, and bullet and cylinder points plus two wheels and 2 point mandrels, separated in four compartments by each grit texture for easy selection. This way, you can have all the tools you need for polishing, smoothing, grinding and deburring work on your firearm in one place.
Recommended: CRATEX Kit No. 227 – Cones and mandrels
This kit contains 18 CRATEX Cones (tapered, cylinder, pointed and bullet cones) in two grits (coarse and fine) and two No. 1341 cone mandrels. Excellent kit for grinding and polishing work on pistol or rifle when you need to reach some hard-to-reach surfaces or spaces.
4. CRATEX Abrasive Rods
CRATEX rods have various purposes in gunsmith work. One of the popular usages is jeweling a rifle bolt. The rifle bolt is mounted on machines like Jeweling Indexer or Wheeler Engineering Bolt Jeweling Fixture. The jeweling swirls are made by abrasive rods, which are placed in Drill Press Quill tubes. The bolt is then placed below the press, and rods are gently lowered down to touch the rifle bolt for a couple of seconds to create a jewel. The process is repeated for as many times needed to cover the entire surface of the rifle bolt.
Centerless CRATEX rods can also be used with Menck Damascening Tool that supports the whole length of the rod. Thanks to the extended design, this tool will allow jeweling around parts like firearm bolt handles or locking lugs. The abrasive rod has a close size control, a feature that will make the "swirls" always equal.
5. CRATEX Abrasive Blocks/Sticks
Abrasive blocks are an item that every gunsmith should own. Coarse grit silicon carbide blocks and sticks are great for removing material or sharpening tools, fast work when the fineness of the cutting edge is not so important. A beginner gunsmith should probably keep a distance from coarse grits and stick to medium or fine stones, which remove material smoothly and softly without digging into the surface. The extra fine grit can be used for putting a finish on firearm parts that are made from metal. Depending on the work, a gun smith can start with the coarse grit and work his way through the grits to the extra fine finish.
CRATEX also offers dressing blocks, which are important if you own a Grinder. Dressing blocks will keep the grinding wheel surface clean and square.
6. CRATEX Large Wheels
For every serious gunsmith, Grinder is one of the top must-have power tools, and CRATEX 6” large grinding wheels can make a perfect package in cases when you are doing cleaning, surfacing, polishing or grinding work. You’ll use this power tool and wheels every time you need to re-shape parts (like recoil pads), sharpen or modify your tools, shorten springs and screws, take off the rust.
Belt Sander is another power tool which is a money well spent. Besides the belt, the machine has a sanding wheel on the side, which is excellent for operations like sanding the rifle stock to fit recoil pads or for shaping them. Of course, a wide sander belt can also be used for stock sanding.
7. CRATEX Moto-Tool and Rotary Handpiece Attachments
Moto-tools are quite handy in a gunsmith workshop for doing a wide variety of small chores, and CRATEX tools are a perfect fit for Foredom or Dremel rotary machines. These tools allow you to mount a variety of different size of attachments suitable for engraving and polishing, mounting grinding stones, cut-off bits, etc.
As a gunsmith, you will certainly also need a small hand-held rotary tool. CRATEX offers a lightweight, stainless steel, high-quality and precision air tool called CRATEX Rotary Handpiece, which in combination with CRATEX abrasive and cut-off wheels, points and cones are used for precision grinding, cutting, finishing and polishing operations on firearms. The small power tool can be used for shaping stocks, modifying parts, cutting slots in screws, polishing internal parts, cutting off metal pieces and cutting holes in your firearms, etc.
CARTEX tools can also be mounted on rotary pieces of different manufacturers, like Dremel, Craftsman, Foredom, etc. in case that’s what you currently have in your workshop. But, if not, CRATEX Rotary Handpiece is a tool to invest in.
8. SPEDECUT Cut-Off Wheels
Spedecut resin-bonded abrasives are double-reinforced cut-off wheels with high tensile strength fiberglass layers on both sides that can be mounted on a hand grinder and used for grinding or cutting off firearm metal parts. For example, Spedecut can be used for making cuts in the receiver while working on de-milling of the trigger guard, cutting off hammer spur, cutting off existing bolt handle to later install a new one, or cut off inadequate factory bolt knobs to replace them with the ones that can provide faster operation.
Interview With a Gunsmith
Welcome, Bill! And thanks for accepting to do this interview with us. Could you please tell us a bit about yourself, maybe something we can’t find on your website?
- My hobbies have always included firearms, however my second love is motorcycles. I have experienced road driving, hill climbing, flat track and motocross racing. Fishing and other outdoor activities have been enjoyed during my lifetime. Last but considered the most important is my sole-mate/wife, Debbie. We met in high school and have been together through all of life sharing business and pleasure. I have been trained as a machinist, certified welder in metal and plastics and experienced in most home remodeling tasks. I have held a patent in plastic welding equipment and I’m considered an expert in containment products for concrete joints. I was CEO of J P Specialties, Inc. for a 35-year period.
How long have you been working as a gunsmith? Can you describe your beginnings?
- I have been gunsmithing for over 35 years. When I moved from the Illinois to San Clemente, California in 1982 I discovered the San Clemente Trap & Skeet Club. After joining the club I participated in many trap and skeet shoots. Many of the club shooters brought me their shotguns for repair or modification. We opened our first retail store in San Clemente and began working with the local police departments and military from Camp Pendelton doing repairs. Several years later we expanded our business and moved to Laguna Niguel. In 1989 we moved the business to Lake Elsinore, California where we purchased a 5,000 sf building. In 2012 I was retired and we moved to Prescott, Arizona. 3 years later we moved to Wickenburg, Arizona where I came out of retirement and opened our new 2,200 sf retail gun store with complete gunsmithing service known as “Poole’s Gunsmithing/ Arizona Custom Firearms”.
Can you describe your (or your team's) day on the job as a gunsmith? Or your typical work week if more suitable?
- We have one full time, professional gunsmith who has over 14 years in special operations military experience whom we employ, my wife and myself. My day starts at 8 am and ends at 4pm. A day on the job is filled with multiple challenges of repairing/restoring all types of firearms. We have repaired firearms from the late 1800’s to present day. Since opening our new store in April 2017 we have repaired over 400 firearms. In the course of a day we are selling new, used or consignment guns. We handle transfers, background checks and discuss technical questions. All gun work is test fired in our bullet trap. We are authorized by the Game and Fish Department of Arizona to sell hunting and fishing licenses.
What gunsmith service do you provide the most at Poole’s Gunsmithing: repair, engraving, customization or some other? Do you work mostly with guns or rifles?
- At Poole’s Gunsmithing we repair all types of firearms and restore them to a safe shooting condition. In addition we discuss with our customers what type of custom firearm we can build to order. We offer long range rifles, target pistols or revolvers and concealed carry. We manufacture our own “Match” AR15 platform rifles/pistols. Our name “Poole’s” and our logo appear on the lower receiver. Poole’s works in conjunction with the best bluing service and engraving service, offering a full service gunsmithing shop.
What's the last project that you did that was especially challenging?
- The most challenging work is usually the older double barrel shotguns. These would be from the early 1900’s to 1940. There were many brand names that were private labeled for department stores and hardware stores. Obtaining schematics and parts is a challenge. These guns require custom made parts and hand fitting for each and every particular gun.
Can you name the most important factors to become a successful gunsmith?
- Apprenticing, formal training, patience, testing your work before returning the gun to the customer. No short cuts. Upfront accurate quotations for your repairs.
What is your advice for those who just started with gunsmith school and career?
- Take the career seriously. Plan to work as many hours as necessary to provide quality work. Always remember the firearm you are working on can take a life or save a life; make sure it is reliable.
What are the essential gunsmithing tools in your shop you can’t work without?
Machinery would be a precision lathe, baldor buffer, disc & belt metal grinder, fordem motor/shaft, barrel vise, milling machine, abrasive blaster, heat treating furnace, air compressor and hundreds of specialty hand tools.
What type of abrasives do you use in your shop: rubber wheels, points, cones, etc.? Please describe the purpose of the use: polishing, grinding, finishing, etc. Why do you need abrasives and in what phases do you use them?
- Belts and discs for the grinder to remove metal fast. Hard 8” wheels for polishing flat surfaces and deburring on receivers and parts. Sewn cloth 8” for use on the buffer for polishing parts. Loose cloth for high luster polish on stainless steel parts. Baldor buffers are handy for polishing large parts.
Depending on the abrasive shape, what size (diameter) and grit type are mostly used by gunsmiths?
- When using a foredom shaft drive tool we use diameters of ¼” to 5/8”. The shape most common is a cone shape or drum shape. Rubber shapes in medium or fine to polish. MX for more aggressive prep work.
You use MX abrasives (aluminum oxide abrasives). What is the main difference (advantage) between those and rubber abrasives? Why other gunsmiths should try MX mounted wheels and cones?
- MX is perfect for removing tooling marks left on parts from milling. Feed ramps on pistols that have machine gouges on the ramps cause jamming. Use MX cone shape to remove marks and then polish with the fine rubber cone or hard felt with the right compound.
Did you try some other Cratex products, like Spedecut cut-off wheels or Brightboy abrasives?
- We use the Cratex small diameter round pencil shaft rods for jeweling metal parts.
How did you learn about CRATEX products? Official website, forum/blog, recommended by other gunsmiths?
- Started using Cratex abrasives in the mid 80’s after visiting “Tussey Custom” in Tustin, Ca. Terry Tussey is one of the best pistol smiths in the country and turned me on to Cratex. He now teaches gun smithing in Nevada.
When did you start using CRATEX abrasives?
Why did you choose our products instead of some other manufacturer?
- Cratex is by far the very best. I say this because Cratex offers a vast variety of abrasive grits, types, and shapes to match my projects. The quality of the Cratex products affords me the opportunity to provide my customers with the best quality product. Without the Cratex products our work would be so much more labor intensive.
What do you like the most? A) Quality & Material? B) Price? C) Customer service? Other (describe main benefits using CRATEX abrasives)
- A, B & C I like them all. The main benefit to Cratex is that it works!!!
Is there anything we could do to make you a more satisfied customer? (product improvement/online store/website/other)
- Yes, mount the rubber cones & drum shapes to a fixed shaft. This would prevent the rubber abrasive from dislodging from the existing shaft design.
Would you recommend CRATEX products to others, and if yes, how would the recommendation sound?
- You have tried other products, now buy Cratex for the results you have been looking for.
Top 5 essential gunsmith tools
As you might imagine, a serious gunsmith is always on a lookout for new tools and gadgets, and therefore, he owns an impressive selection of tools and machines which help him do his work and take his creations to the next level. However, even if you are not a professional or a gunsmith at all, but you own firearms and you wish to do minor work or modify your guns from time to time, you’re still going to need tools for gunsmithing.
In this line of work, there are some tools you cannot go without, so we focused on basic tools every gunsmith (both serious and weekend hobbyist) should own. Then, we thought about the non-gunsmiths as well, and came up with a list of Top 5 Must-Have gun Smith Tools.
1. Gunsmith Screwdrivers
Each gunsmith, firearms hobbyist or a gun owner should invest in some specialized gunsmithing screwdrivers. Why? Because hardware store screwdrivers are not same as screwdrivers made for gun smiths. Ordinary screwdrivers are not well suited for gun work and can damage screw edges and can damage the finish as you apply pressure, while specialized screwdrivers have tapered and beveled heads, which fit properly in most screw slots found on various types of guns. The blade needs to fill the screw head completely, as a perfect fit provides control, eliminates tilt and wobble, and prevents you to injure you hand and your weapon.
The two types used most often are magnetic-tipped and fixed-blade screwdrivers. Screwdrivers with magnetic tips have hollow magnetic ends, which hold the screw against the bit, and are quite handy when you’re working with the smallest gun screws. Fixed-blade screwdrivers provide more strength and maximum control.
We can suggest Brownells, as they have a wide selection of different single screwdrivers and sets, both with fixed blades and magnetic tips.
2. Gunsmith Pin Punch Set
Pin punches are designed to easily remove roll pins from firearms which are encountered during the repair or assembling. You can purchase one pin punch, but it is recommended to buy a whole set, in order to have an appropriate size punch at hand (using the wrong size punch can cause the pin head to flare and can ruin the firearm surface. It is also recommended to have steel punches as well as brass punches. Brass punches won’t mar the surface as you tap in a pin, because it is much softer than the steel pins.
The balled tips of pin punches, like the ones from Grace USA, help locate the punch on the pin and they protect pin ends from damage during removal or installation.
Professional gunsmiths have an entire assembly of different types and sizes of punches, including at least starter punches, drift punches, pin punches and roll pin punches. It doesn’t matter whether you have one or many punches, important is to invest money in quality (brands like Brownells, Starrett, Craftsman are high-quality). Cheap punches will bend and brake plus get your workpiece in danger.
3. Gunsmith Hammers
Hammers are used for hitting pins and getting them in their place. Of course, gunsmith hammers are designed to do so without leaving a scratch or chipping the surface of the gun. Most commonly used hammers are brass hammers, because brass won’t damage the steel and marks left by it can be removed quite easily. Brass hammers are used mostly for driving stubborn pins, freeing up choke tubes or tapping frozen screws.
You buy combined hammers, with heads made out of brass on one side and nylon on the other as nylon can be used during delicate jobs which require precision and carry danger of ruining the gun finish.
Second options is to buy ball-peen hammers, since they provide excellent balance and control during precision work on the one hand, and maximum striking force applied to a small area when using the ball-peen side. Experienced gunsmiths say that a small 14-ounce ball-peen hammer would be sufficient for most work.
Some also invest in gunsmith rawhide mallets like the C.S. Osborne mallets because rawhide hammers deliver precision blows which protect pins, punches and soft parts of the firearm and won’t damage wood nor metal. Dead blow rubber mallets are also recommended for minimizing the damage of the surface in cases where you need to apply some pressure, and a 14-ounce mallet would do the job perfectly.
Special packages: You also have the option to purchase these top 3 basic tools in a gunsmith tool kit, like the one from Grace USA. It’s a basic firearm care tool set which includes screwdriver and brass punch sets and an 8-ounce brass hammer.
Screwdrivers, punch pins and hammers are considered basic tools in case you want to just take the firearms apart and put them back together. However, 2 more tools are considered essential if you want to take good care of your firearms and want to make your job a lot easier.
4. Gunsmith Vise
Every gunsmith or firearm enthusiast should invest in a good vise, as it is essential for holding a firearm still during repair work or assembly. Many coat vise’s jaws with leather, because the leather protects the firearm’s finish additionally, while others purchase protective soft magnetic jaws, like the ones here. Soft jaws are used, for example, for clamping down barrels and are designed to hold them firmly enough to get the job down without damaging them. Hard jaws (for example, made of heavy duty phenolic) are also handy and are used to clamp down heavy pieces without damaging the finish of a gun.
There are all kinds of bench vises for gunsmithing, like the ones that are fastened to the workbench or the ones that are secured to a block of wood. There are also vises that can be positioned both horizontally and vertically and that can be adapted to any job you are conducting whether sanding, soldering, stock work or drilling. It is especially useful when you work on small parts, like holding a trigger sear for stoning.
You can get by with small, temporary mounted clamp-on vise, but it’s always better to invest in a medium size (4-6 inch jaw size) vise which is permanently mounted on a workbench with a strong foundation. Make sure you attach it to your workbench in such a way that it allows you to approach your workpiece from every angle. After all, vise is one of gunsmith’s essential tools on his workbench, so invest in a good vise with rotating heads.
5. Bench Block
Bench blocks are used to stabilize parts of the fire weapon and prevent them from rolling during pin driving or pushing, which makes any detailed work much easier to perform.
Bench blocks are produced in various sizes, some are shaped based on the specific models of guns, and the holes in them let pins drop free. Because bench blocks cannot damage the firearm’s surface, they are made of materials such as wood, nylon or polyurethane.
If you do a search on Google about gunsmithing salary, you’ll get a pretty straight answer $32,267 on average per year. Since this figure came out from five years old research we decided to dive deeper into these numbers and check firsthand how much money you can make as a gunsmith.
Is Gunsmithing a Good Career?
Like any other professions gunsmiths can earn a wide range of salaries depending on many circumstances, but most important is the experience and how long you are in the business. A simple fact is that gunsmithing is definitely not the highest paid job in the US but you can earn a decent living from it.
According to PayScale research that is updated on September 27th, a gunsmith earns on average a wage of $15.51 per hour. The range of total pay goes from $24,520 to even $62,948. Six-figure gunsmith salaries are rarely reported and can be achieved by true experts and master gunsmiths.
Factors That Affect Gunsmith Salary
How much money you can make depends on a lot of factors. They can be general for sure and influence your wage in the same way as other on a national level, but we’ll stress most important related to gunsmithing industry. Of course, we’ll assume this is your full-time job and not a hobby.
- Factor #1 – Experience. This isn’t a #1 factor without a reason. As time goes by you will gain experience and be able to work on a delicate project like gun restoration, design, customization, etc. Working on complex projects (and doing it them right) will put you in a position for a higher hourly wage.
- Factor #2 – Reputation. There is no need to explain why reputation is important for every job. As you gain experience and skills your portfolio will become richer. A successfully completed task will build your reputation but be patient and don’t expect miracles to happen overnight. Building reputation needs time.
- Factor #3 – Specialization. One of the factors that have the biggest impact on gunsmithing salaries. When you acquire basic knowledge as general gunsmith it is the right time to think about specialization. Engraver, custom designer or finisher are just some of the fields where you can focus and become an expert. Engraving whole or just part of the gun is more paid than simple gun cleaning.
- Factor #4 - Do you run your own business? Running your own business usually means a higher salary (few gunsmiths reported $100,000 income per year), but this also brings some other risks as well. You need to worry about benefits, tools and breakages. Your paycheck is not guaranteed when you are your own boss. On the other hand, you have flexible working hours and freedom to work on projects you find tempting. Starting your own business just after graduating is maybe a not such a good idea. Consider the fact that tools can cost you more than $10K.
- Factor #5 – School (certifications and training). Owning associate of occupational studies degree in gunsmithing or certificate and advanced training program can be a real boost to gunsmith salary. Additional degrees can put you in a position to ask for more when negotiating with a potential employer. Check Chapter 4 to see the best gunsmithing schools in the US or download our eBook with ALL gunsmithing schools with their contact information.
- Factor #6 – State where you are doing business? Location of your shop or workshop (combination of retail gun store and gun repair shop) you are working for, along with local demand in most cases means different salaries too. Gunsmith salary in Texas is much higher compared to one in Mississippi. One of the highest paid states for gunsmiths is New York with $85,000 salary per year.
A lot of good gunsmiths do blogging as gun experts. They write specialized articles for online gun magazines, blogs or even forums. Some of them are great forum administrators. Since these blogs and forums have large audience many of them earn extra bucks renting web space for gun and armor shops.
Advice for Beginners
Like every other profession, gunsmithing has some specifics and uniqueness. Master gunsmiths have several pieces of advice especially for those who just graduated and are looking for their first job as gunsmiths:
- Don’t worry about the money. As you are just starting out making $12 per hour plus benefits is very good.
- At the beginning of a carrier you need to learn as much as possible. Don’t think you know everything just because you have a gunsmith degree or certificate!
- At the beginning, your will mostly work on gun cleaning. Don’t let that discourage you.
- Invest in the best tools you can afford. Never buy cheap ones!
- Invest in knowledge, accept new things (like using software for gun designing) and be willing to work long hours.
- Don’t accept work you are not capable to do, breakages will cost you a lot!
- Pay attention to every detail. That is the only way to build a reputation.
- Respect and adopt knowledge and experience of older gunsmiths. Learn their tips and tricks. It is not just about book knowledge.
- Don’t overload yourself!
- If you are going to sell guns as well, you need to be a good businessman too.
- Try to specialize in finishing, engraving and other gun customizations.
- Start creating your own knowledge base and library from the day one.

How to Become a Gunsmith
You can say that a gunsmith is a person who repairs, customizes and/or builds firearms, but it won’t truly illustrate the skill set and width of knowledge a gunsmith must own to be able to do what he or she does.
A gunsmith can perform quite simple tasks, for example, inspecting, cleaning, disassembling and reassembling a firearm, but is also capable of performing complex tasks, including metal refinishing, wood and metal engraving, or design. Therefore, a master gunsmith must possess a wide range of skills which make him part fabricator, part mechanic, part metalworker and wilder, woodworker and part an artist.
First, a gunsmith needs to know his/her guns – must be familiar with all kinds of types and models of firearms to be able to customize their parts, analyze and improve their performance.
A gunsmith must possess knowledge in the use of numerous hand and power tools, measuring devices and machinist tools. Not only is machine shop knowledge required, but also knowledge in: mathematics, materials engineering, ballistics, chemistry, and, of course, running business.
And above all, a gunsmith must be a good artist, both when it comes to coming up with the design and transferring it on a piece of paper and engraving or carving the wooden or metal part of the firearm.
Since the road to becoming a professional, master gunsmith is a long and exhausting one, and since not all gunsmiths can possess all previously mentioned skills, many of them focus on becoming specialist in preferred areas: custom building/designing, finishing work, stockmaking, checkering, engraving, some specialize in work on revolvers and pistols only (pistol smiths), and some become manufacturers of certain types of gun parts and focus on distribution and sale to other gunsmiths.
But, how do you become a gunsmith in the first place? This chapter contains information on precisely what it takes to become a gunsmith.
Technical Skills of the Trade
Gunsmiths can create true pieces of art, but it’s not just art what gunsmithing is. Guns that are designed and build must also be safe and must function properly, as the slightest technical slipup could result in serious injury or worse.
A gunsmith must become primarily skilled in woodworking, metalworking and machinery. He or she must also get familiar with numerous other shop materials, as this knowledge is essential for creating good-quality guns.
This involves using various wood shop and metal shop equipment, such as drill presses, drills, hand rotary and air tools, cutting tools, grinding tools deburring and metal polishing tools, precision measuring instruments, files, chisels and so on.
Math skills are also important, as gunsmithing involves a lot of measuring, precise cutting and executing calculations for technical specifications, but mechanical expertise is essential. Namely, a gunsmith must understand how a gun works, must understand its components and how they move and work together. Understanding gun mechanics is crucial for assembling all parts properly, but also for identifying a problem when a gun isn't working as it was supposed to.
Being an engineer is not a must, but it is certainly recommended. You would learn more advanced calculations, ballistics and so on, which can be very helpful for the profession.
Interest in History and Production of Guns
As a gunsmith and a gun enthusiast you must be interested in the history of firearms. From the dawn of the firearms in the 1200s China to the long period of development of modern weapons to the introduction of automatic handguns at the end of 19th century, the history of firearms is extensive and impressive.
Not all gunsmiths are interested and familiar with all eras – some have more extensive knowledge of historical firearms and some lean more towards the contemporary period. Either way, gunsmiths are usually collectors or hobbyists, which means that the fondness they felt towards firearms developed a desire to repair or craft guns on their own.
Regardless of the preference and the knowledge base, gunsmiths are always keeping track with new developments, new models, accessories and manufacturers. Many of them attend conferences, events and trade shows to meet other gunsmiths, learn more and teach others more by sharing their experiences.
Understanding the Importance of Gun Safety
Every gunsmith knows that guns are no toys and that they should be handled with respect, responsibility and according to standard safety rules and laws. All successful gunsmiths are committed to gun safety.
A gunsmith is responsible for more than just creating an impressive gun for a showcase. A gunsmith carries responsibility for creating a gun that is not faulty and dangerous for the user. It is important to always follow safety guidelines, laws and regulations to protect your customers.
Education and Training
Of course, the earlier you start, the more skills you'll develop over time. The best would be to start in high school by taking courses, such as machining, woodworking and drafting, as these will help you obtain basic skills needed for the trade. However, in case your high-school days are long over, and you failed to obtain such a skill set, don't worry as it's never too late to learn.
By enrolling in a gunsmithing school or by starting an apprenticeship, you take the next step towards transforming your firearm hobby into a rewarding career that involves learning about altering triggers and safeties, diagnosing accuracy problems and preforming important self-check procedures.
Here are different ways that can bring you closer to achieving your goal of becoming a professional gunsmith.
A good idea would be to start an apprenticeship to build basic craftsmanship and knowledge. So, how to become a gunsmith apprentice? Gaining hands-on experience by learning directly from an expert is a one way to go, so make sure you seek out a local, experienced gunsmith.
You can also apply for an apprenticeship status through The Association of Gunsmiths and Related Trades. TAOGRT tends to match experienced sponsors with students looking for getting gunsmith apprenticeship.
A great thing is that the apprentices are paid for their work. Quite often they start working for a minimum wage that increases over time and with experience.
To become an apprentice, you must be 16 or older, and you'll need to be able to legally own and possess a firearm in compliance to federal and state laws. If in high school, you'll also need to graduate and maintain at least a "C" average, combined with a permission from your legal guardians and school officials.
As an apprentice you'll learn how to safely use gunsmithing tools, such milling machines and lathes, you'll learn how to make fixtures, make and fit gunstocks, perform barrel work and action work, and learn all there is to firearms theory. Sometimes apprentices are required to purchase their own tools to use over the course of their training.
To help ensure proficiency, TAOGRT has developed certain standards like competency exams. There are specified numbers of hours that an apprentice must spend gaining experience in order to complete the gunsmith apprenticeship. Also, the apprenticeship will last a minimum of four years for a standard gunsmith training.

You don't need a "gunsmith license" to be a gunsmith, but you do need a Federal Firearms License (FFL) if you want to become a licensed gunsmith. The FFL gives you a legal right to possess other people's firearms for an extended period.
Since you don't own a permit for other people's firearms, this license will allow you to maintain possession of another person's firearms for as long as it takes to repair, test and work on them.
The process of getting the license is very strict and involves an on-site interview with a federal field agent. First, you'll need to be over 21. Next, you'll apply for it through the US Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF).
The specific form is called "ATF 5310.12 (Form 7) Application for License" and it can be downloaded from the ATF website. The basic license that authorizes you to work with shotguns, pistols, revolvers and rifles is "Type 1".
You'll also need to submit a copy of your fingerprints and a fee along with the application. The ATF will run a criminal history background check and the federal field agent is going to inspect your gunsmithing tools and facilities, ask you questions to determine whether you are experienced enough and whether you conduct the best gun safety practices.
The gunsmiths with Federal Firearms License must also meet bookkeeping requirements that are set by the ATF. Every firearm that is left with a gunsmith overnight, must be recorded and kept in the shop's "bound book".
Choosing school or college can be very hard. Some even call it a lifetime decision. There are a lot of questions you need to answer that is for sure. One of them, maybe major one is – should I follow my heart or head?

5 Ways How to Beat Rust on a Gun and Firearm
No matter you place a gun in the back of a wardrobe, behind a car seat or in an in-ground stash, taking the time to protect them versus the ravages of time and nature will provide it live long enough for your offspring to use.
Rust occurs on guns because they are typically metal object. Even the best arm can scratch and fade over time, and rust just shows inevitably. Carry guns are rust friendly because of proximity they have with the human body. The human body is a big rust maker because of sweat. Sweat actually ruins guns. If you live in humidity areas, guns can rust rapidly.
Most modern guns are anodized with a coating that guards against rust. Anyhow, even anodized and blued surfaces can’t stop rust forever. In this article, we’ll show some easy techniques on how to remove rust from a gun.
How to Remove Heavy Rust from a Gun with Dremel
Age or exposure of firearms to the humidity or ambient air can make rusted spots on your favorite gun. To avoid that "rusted situation" use Dremel rotary tool with CRATEX rubber bonded small abrasive wheels.
They’re made of high-quality silicon carbide and are ideal for operations such as: removing rust from old guns, removing trigger serrations, removing stretches, rounding edges, cleaning up worn or damaged pistol and rifle markings and engravings, polishing flash pan, bolts and feed ramps, smoothing surface and getting almost mirror finish, jeweling a rifle bolt or pistol barrel, etc.
CRATEX abrasives come in 4 standard grit textures which differ in color: Course (green), Medium (dark brown), Fine (reddish brown) and Extra Fine (grey-green). There is also the possibility to change standard shapes and grits and get a modified abrasive tool that meets your needs much better.
Follow these few steps on how to remove rust from a gun with a dremel.
The most important thing, make sure that firearm is unloaded. Then, insert CRATEX small abrasive wheels on a rotary tool. Apply a few drops of gun oil on a rusted place. Wait for a while.
Start running with Dremel against an oiled rusted surface. Use napkins or paper towel to wipe the rusted area. Continue with removing process until you get a clean and smooth surface. Use a dry clean cotton cloth and clean any rust residentials.
You finished gun rust remover process and got a brand-new firearm without rusty spots.
Removing Rust from Gun with Steel Wool
When you're cleaning a gun, the abrasive material has a crucial impact. Applying wrong abrasive material can ruin the finish of the firearm. Using a steel wool pad is an effective method to remove rust from a gun. It’s smooth and easy to use.
Lubrication plays an essential role in rust removal also. Any kind of oil can be applied for this project. There are plenty of oils that are specially made for firearms. You can use cooking oil and ‘3 in 1’ oil. Napkins or some used newspapers are the things that you need too.
Follow the lines below on how to remove heavy rust from a gun.
Double-check if the gun is loaded or not. If it’s loaded, then unload it to ensure your safety.
Try to keep the work area steady and quiet to keep your focus. Use the napkins or newspapers for collecting the wastes and for other cleaning needs.
Put the gun calmly so that it doesn’t move while cleaning. Always keep the gun pointed in a direction that is safe because there is a possibility of getting misfired if the gun is loaded.
Pour oil on and around the rusted surface. Avoid using large amounts of oil. Apply a few drops.
Use the steel wool pad as an abrasive material to rub the gun surface. Don’t use much pressure so the finish of the gun would be ruined.
The finish of the firearm might be damaged if done improperly. Then you add gun cleaner on steel wool and rub it lightly on the rusted area. After some time wipe the gun with the napkins or and check it thoroughly.
If the rust stays, rerun the process again, until the gun becomes rust free.
Cleaning Rust of Gun with Oil
Make sure that before beginning rust removal process, you feel the texture of the gun so that later on you can see the difference after you're done the job. This is the most effortless technique of all, just read the instructions below.
Always, double-check that the gun is unloaded to avoid injuring yourself or others.
First, apply the firearm oil on the rusted surface, don’t add a lot of oil.
Let the oil to sit for a while to loosen the rust grip on the surface, and this will boost the contact of oil and rust. That cause loosens the grip of rust on the gun.
Apply a cotton cloth to wipe its surface. Skip using large amounts of oil as much as possible.
If the rust remains, keep cleaning the surface until the gun becomes rust free. This depends on the depth of rust on the arm.
Use soft steel wool or copper brush to rub the surface. Ensure that your index finger can move through a circular manner as you guide the steel wool on the rust areas. Repeat the operation until you have a sheen surface. If you are done a good work, you will see the clean oil changing color from being clear to a rusty color.
Remove the surface sediments that may be there during the rust removal. At the end of the process just clean the gun with a cotton cloth, and that's all.
Battery Changer as Gun Rust Remover
This is an excellent solution of removing rust, it's mostly recommended for copper, brass, aluminum and alloy sort of firearms. For this method, you need a plastic container, steel rod, baking soda, and battery charger. Be extremely careful while doing this task and inspect is your gun loaded.
Mix 1 tablespoon of baking soda with a gallon of water and you make electrolyte. Then put steel rood cautiously in a container, the rode will be anode (positive terminal), and the cathode will be the solution.
Connect the cathode to the rusted surface and anode to the rod, make sure that charger is plugged in. Bubbles in water show that the process is going on. Let it sit there for three to five hours. After that, just remove the gun parts and wipe it with a cotton cloth. This is one of the best ways how to clean a gun with household items.
How to Get Rust Off a Gun With WD-40
It’s an option recommended by many gun industry owners because of its moisture displacement and rust preventing properties. Before applying the WD-40 solution be sure that arm isn’t loaded.
This technique is quite simple. First, you need to put the arm on the flat surface. Then, spray the WD-40 solution on the rust area. Let the solution stay on rust surface for 24 hours and then respray it. Wipe the surface with a rag or a napkin, and you got a brand-new gun again.
Preventive Measures Against Rust
The quickest method to prevent rust from returning is to wipe down all gun surfaces with a dry cloth. The moisture accumulation, especially salt water speeds up the steel oxidation and iron surfaces.
The drier the gun, the less possibility there is for rust to show. If you put unused firearms in a safe with a desiccant, the desiccant can eliminate surplus water from the air.
So, the key to preventing rust is to keep it as dry as possible. Regular maintenance and cleaning, once or twice a month should be sufficient for most arms.
Best Storage Conditions
To be the most efficient at preventing rust, you must store a gun in a cool, dry place. If you want to be very precise, the NRA National Firearms Museum keeps their collection stored at a constant 70°, and 50 to 55% humidity.
For most folks, this stage of precision is not easily reachable, so just try to store it in the driest place you can and that way, you prevent rust appearance on the firearm for some period. Avoid places like attics, garages, and the trunk of a truck. It is also an excellent option to skip leaving guns in their cases, as these can often be a trap for moisture and cause rust.
Still, you can pack all the dehumidifiers in your gun, but it won’t prevent a firearm from corroding if you forget to clean them after using. If you really want your gun stays rust free, you will need to provide they are clean, properly oiled, and stored in a dry, cool place. If you can achieve all of these things, it should be the crux that your guns stay in best condition for an extended period.
