It has been suggested that Firearm modification be merged into this article or section. (Discuss) |
A gunsmith is a person who repairs, modifies, designs, or builds firearms to factory or customer specifications, using hand tools and machine shop tools (such as lathes, milling machines, and grinders).
Gunsmiths may be employed in:
- factories by firearms manufacturers,
- armories by military or law-enforcement agencies,
- sporting goods stores, or
- small gunsmith shops, as either the owner, or as one of a handful of employees.
To pursue the entirety of this trade, a gunsmith must possess skills as a mechanic, a metalworker, a woodworker, and an artisan; be knowledgeable in shop mathematics, ballistics, and chemistry; and be capable of working accurately and precisely. Those who are (self-)employed in small gunsmith shops must also possess skills as small business operators; work effectively with a wide variety of customers; and remain abreast of, and comply with federal, state, and local laws, ordinances, and requirements.
Due to the great breadth of subject matter to be mastered, many gunsmiths specialize in only a few of the skills required of the general gunsmith (see Specializations section below). Alternatively, some gunsmiths learn many of the skills of the trade, but only apply them to a few weapon types (only pistols, or only shotguns, or only (pre-1964) Model '94 Winchester Lever-Action Rifles; for instance).

[edit] Legal Requirements
This article cannot pretend nor even begin to cover the legal issues surrounding gunsmithing and gun ownership. Please be advised that there are many gun laws and requirements at all levels of government. Failure to abide by these restrictions can result in extremely severe penalties.
In the United States of America, the Bureau of Alcohol, Tobacco, and Firearms[1] is the primary federal agency overseeing firearms. The Federal Bureau of Investigation[2] is also involved, operating the National Instant Criminal Background Check System (NICS) to approve firearms sales.
Laws and regulations vary greatly from state to state, county to county, city to city, and potentially across all jurisdictional lines.
Note too, that these laws may change frequently, particularly as new administrations take office, as court cases are decided, and as existing legislation and amendments to the United States Constitution are reinterpreted.
These laws may also vary by:
- firearm type (handgun? longarm? rifle? shotgun?)
- firearm model (assault weapon? automatic weapon? caliber?)
- intended modification (minimum barrel length? magazine size? fully-automatic?)
- customer or recipient (legal owner? felon? background check?)
- quantity of firearms (how many per week? per month?)
etc.
It is the gunsmith's responsibility to ensure that all requirements pertaining to the practice of this trade are complied with. Seek competent legal advice!
[edit] Responsibilities
The primary technical responsibility of gunsmiths is to ensure that the weapons they work on function safely.
They accomplish this firstly by always properly observing gun safety handling procedures: both in their own actions, and in the actions of their customers and the people around them.
They accomplish this secondly by inspecting firearms to ensure safe mechanical operation. Gunsmiths use their in-depth knowledge of firearms to guide these inspections: either repairing deficiencies; or notifying customers of unsafe conditions and taking steps to prevent catastrophic failures.
Only some of the ways that even properly handled firearms can fail and endanger their users and those around them are:
- Improper Assembly
- Missing Parts
- Cracks: all cracked parts are cause for concern, but especially so in the chamber-area, bolt, bolt-lugs, or buttstock.
- Bore Obstructions: being either dented or bent barrels, or foreign material in barrels.
- Improper Headspace: dimensions concerning the relative locations of the chamber and the bolt are not within specified tolerances.
- Improper Timing: (applies to fully automatic firearms).
- Safety-Mechanism Malfunctions: potentially allowing a firearm supposedly on SAFE to unexpectedly fire.
- Worn Sear Edges: potentially allowing a firearm not on SAFE to unexpectedly fire.
- Firing-Pin Tips Deformed: leading to the possibility of primer-rupture.
This list is not comprehensive! Many failure modes are dependent on the particular model of firearm.
[edit] Common Tasks
(listed in approximate, but not exact, order of increasing difficulty)
- Keep records of all customers, firearms, and transactions to satisfy ATF requirements.
- Disassemble, clean, inspect, lubricate & reassemble.
- Remove corrosion and touch-up finish.
- Repair burred or damaged parts with files & stones.

- Measure & correct headspace dimensions.
- Check for excessive bore erosion.
- Troubleshoot and repair feeding, ejecting & firing problems.
- Test-fire firearms with conventional loads to ensure proper operation.
- Fabricate wooden stocks to customer specifications and body dimensions. Fit same to existing receiver and barrel.
- Glass-bed actions to stocks to improve accuracy.
- Remove existing metal finish, and re-blue metal parts.
- Fabricate replacement parts from metal stock.
- Modify trigger-pull weight through careful stoning of trigger mechanism parts.
- Fire proof-loads through weapons to insure sufficient strength of parts under over-load conditions.
- Replace worn barrels, which have fired so many rounds that they are no longer of the specified caliber (which leads to loss of accuracy).
- Change caliber or cartridge of existing rifle, by changing barrel, and modifying receiver.
- Recut rifling and change caliber of existing barrel.
- Design and build complete rifles by fitting stock barrels to stock receivers; fabricating or purchasing additional parts as needed, and fitting same to rifle. Fitting custom stock to same.
- Design and build a complete rifle starting with several pieces of blank steel and a slab of walnut; using nothing more than a lathe, saws, files, chisels, & rasps.
[edit] Specializations
While some gunsmiths are general practitioners in this trade, some of the more important specializations are:
- Custom Builder/Designer - Builds guns to customer's specification, from raw materials and shelf parts. Called upon by professional target-shooters to create highly accurate custom rifles. Likely the most highly skilled of gunsmiths, as they are required not only to have proficiency in the other areas of gunsmithing, but must also be well educated in machining, in order to manufacture the individual components and springs before assembly takes place.
- Finisher - Applies various chemical processes (browning, bluing, Parkerization, among others) to the metal parts of guns to develop corrosion resistant surface layers on the steel. Cyanide case coloring is a combined chemical and heat-treatment process which develops mottled tempering colors on steel surfaces: greatly valued for their appearance. Typically, its use is usually restricted to receivers, rarely barrels. Although providing corrosion resistance, the colored surface layers are subject to wear: antique firearms for sale frequently stating what specific percentage of the factory original case coloring remains.
- Stockmaker - Carves gun stocks from wood (usually walnut; although birch, maple, and apple wood, among others, are frequently seen). Fits stocks to the metal parts of the gun (receiver and barrel), as well as to customer's body dimensions. The form of stocks are executed using saws, chisels, gouges, rasps, and files. The surfaces are then finished by sanding, scraping, staining, oiling, or lacquering.
- Checkerer -
Simulated checkering on plastic pistol grips.
Checkering tools, showing tiny saw-teeth used to create v-grooves.(This specialization is frequently combined with that of the Stockmaker) Uses checkering tools to create an ornate pattern of small raised diamonds in the wood surfaces which are to be gripped. The checkering tools are in effect tiny saws, designed to leave a v-shaped groove (of approximately 60 to 90 degrees) in the surface of the wooden gunstock. Special checkering tools consisting of two saw blades in parallel are used to set the spacing (between 16 to 24 lines per inch). The area to be checkered is covered by one set of such grooves parallel to each other. A second set of parallel grooves is then executed across the first set, at approximately a 30 degree angle, leaving the area covered with small pointed diamonds. The edges of the checkered area are frequently ornamented with simple bas-relief wood carving, frequently variations on the fleur-de-lis.
A gunsmith checkering a the stock of a rifle. - Gun Engraver -
Uses hand-gravers or die-sinker's chisels to cut designs or pictures into the metal surfaces of the gun, primarily the receiver. Pneumatically driven engraving systems, such as the Gravermeister, developed by GRS, may be used to replace or supplement hand-powered engraving. Other metals (especially gold and silver) may be inlaid and engraved to further the design. Designs usually consist of elaborate scroll-work based upon Acanthus leaves or vines, or may be of purely abstract spirals. The pictures are usually of game animals or birds, and hunting dogs. Before the development of corrosion resistant surface treatments for steel, gun surfaces were engraved to retain more oil to prevent rust. In modern usage, guns are engraved purely for artistic reasons. Top grade engraving may add significantly to the value of quality firearms.
Hand Gravers: hand-powered tools to engrave metal. - Pistolsmith - Specializes in work on pistols and revolvers. Pistolsmiths should be proficient in a range of skills such as woodworking, checkering, machining, metal finishing and metalworking. They must have an excellent understanding of the mechanical characteristics and function of the guns they work on. Often a pistolsmith is called on for extensive customization of a handgun. A good pistolsmith can turn a poorly constructed firearm into one that looks and handles much better.
- (Niche) Manufacturer - Some gunsmiths used their experience and skills to become small-operation manufacturers, specializing in making only a few types of gun parts, for sale to other gunsmiths and gunmakers. Some of the more important part categories are:
- barrels
- trigger assemblies
- receivers
- locks (as in 'flint-locks')
[edit] Training & Education
All gunsmiths develop and expand their skills through years of experience.
Common ways to get started in Gunsmithing include:
attend Murray State college, Co school of trades, Trinidad State College
- Community Colleges and Correspondence Courses: offer various courses of study (less than two years long) leading to a degree or a certification[3].
- Military Training: the U.S. Army trains and employs MOS 45B Small Arms Repairmen [4].The U.S. Air Force trains and employs Combat Arms Instructors (Firearms instructors and small arms repairers)AFSC(MOS) 3P0X1B. The U.S. Marine Corps trains and employs MOS 2111 and 2112 [5]. Contact a local recruiter for more information.
- Apprenticeships: learn directly from active gunsmiths. Talk with gunsmiths in your area, and offer your help around the shop in exchange for learning about this trade.
- NRA Courses: the National Rifle Association offers short courses in many common tasks and skills of professional gunsmithing. Contact the NRA for details [6].
Basic machinist skills, while not limited to gunsmithing, are of great help to aspiring gunsmiths. Typical ways to learn machinist skills are:
- High School Shop class.
- Vocational Education.
- Community College courses.
- Apprenticeship programs.
The above information may get one started, but experience at the bench and with individual firearm models is irreplaceable. There is a great deal of information available in print, so self-study and development of new skills is always an option.
Although there is no shortage of paperwork and forms to regulate the activities of practicing gunsmiths in the United States of America, there is no federal certifying or licensing requirement concerning the skill level of someone purporting to be a gunsmith. News of the most highly skilled and talented gunsmiths typically spreads by word of mouth, based on the quality of their work. Beginning gunsmiths' businesses usually start rather slowly, frequently as a second job. It sometimes requires years to develop enough of a customer base to quit your day job and practice gunsmithing full-time. The very best and most talented gunsmiths, however, command premium prices for their services, and may have waiting lists booked for several years in advance.
[edit] DIY gunsmithing
Do-it-yourself gunmaking has also been practiced by many people around the world. Especially in certain third-world countries as Afghanistan, Jemen and other countries in the Middle East, diy-gunsmithing has become popular. This popularity has been enhanced by certain anarchist books (eg The Anarchist Cookbook, Ragnar Benson's "Guerrilla Gunsmithing: Quick And Dirty Methods For Fixing Firearms In Desperate Times",...), official U.S. Army Field Manuals (which were distributed by the US [7][8][9]), and extremist manuals (eg by Al Qaeda [10], Hezbollah [11], ...)
