The Definition of Federal Firearms License
Federal Firearms License
A Federal Firearms License (FFL) is a license in the United States that enables an individual or a company to engage in a business pertaining to
the manufacture of firearms and ammunition or the interstate and intrastate sale of firearms. Holding an FFL to engage in certain such activities has
been a legal requirement within the United States since the enactment of the Gun Control Act of 1968.

A rib extension on a break-open gun, ending in a circular or semi-circular shape in plan (resembling the head of a doll),
mating into a similarly-shaped recess in the top of the receiver, designed to resist the tendency of
the barrels to pull away from the standing breech when firing.
Because an action's centerpoint of flexing when firing is at the base of the standing breech, not at the hingepin, a passive doll's
head extension makes an effective extra fastener, even without additional mechanical locks operated by the opening lever.
A type of firearm which, utilizing some of the recoil or some of the expanding-gas energy from the firing cartridge,
cycles the action to eject the spent shell, to chamber a fresh one from a magazine, to cock the mainspring and to fire again.
Such a firearm will fire continuously as long as the trigger is held back, until the magazine is empty. A machine gun.
A firearm thus activated, but which shoots only one bullet with each separate pull of the trigger,
while often erroneously referred to as "automatic" is properly termed Semi-Automatic.
Single shot pistols, of a design originating in England, in vogue circa 1770 - 1850, built necessarily in pairs, either of flintlock or percussion ignition,
usually finely made and cased together with loading accessories. Dueling pistols tended to be lighter and sleeker than their contemporary service pistols.
They tended to have smoothbore (or sometimes secret, scratch-rifling), octagon (or octagon-to-round) barrels around nine or ten inches long of some form of damascus steel,
bores just over a half-inch, ramrods, rudimentary sights front and rear, single-set triggers, roller-bearing frizzens and curved grips integral with full or half-stocks.
They were usually of high quality construction, sometimes with silver furniture, but normally of relatively plain decoration.
The substance which imparts movement to the projectile in a firearm. In a firearm, usually powder. In an airgun the propellant is air or Co2
A small hole in the barrel of a gas-operated firearm through which expanding gases escape to power the autoloading system.
The tendency of a firearm when fired to move backwards, and a little upwards as a reaction to the force of the projectile moving down the barrel.
As Newton says, to every action there is always an equal and opposite reaction. The mass of the firearm provides some inertia to counteract the momentum of recoil.
What remains is absorbed by at the shoulder or the hand. The heavier the gun, the less the recoil. The more powerful the cartridge, the more the recoil.
The official US military designation for the Colt .45 semiautomatic pistol adopted by the US in 1911.
The gun was designed by John Moses Browning, and produced by Colt.
During trials, the Browning-Colt design beat out several competing designs, including one from Savage and a .45 caliber version of the German Parabellum ("Luger").
The M1911 saw its first combat in the Philippines and then in World War I.
Early use showed that it could be improved and in 1921 the M1911A1 was introduced, which featured a few changes like a reocontoured frame,
shorter trigger, and a rounded backstrap. The M1911A1 remained the standard US military handgun until it was replaced in the 1980's by the Beretta M9.
However, it remains very popular with civilian shooters in the US, and has been modified extensively to update it to
conform to more modern theories of handgun usage.
A device used to load magazines or revolver cylinders quicker than by hand.
A short stock, often ideally sized for teenagers, average-sized adult women, and small-statured adult males.
Any piece that projects from a firearm for the purpose of attaching something to it.
For example barrel lugs are used to attach a break-action shotgun barrel to the action itself.
If the firearm is a revolver, the term may also refer to a protrusion under the barrel that adds weight,
thereby stabilizing the gun during aiming, mitigating recoil, and reducing muzzle flip. A full lug extends all the way to the muzzle,
while a half lug extends only partially down the barrel. On a swing-out-cylinder revolver, the lug is slotted to accommodate the ejector rod.
A horizontal wedge, press-fit through the forend of a vintage gun, through a lump
attached to the underside of the barrel and out the other side of the forend.
To secure the forend in position. Also called a crosspin or a wedge fastener.
Plugs of hardened steel, precisely machined in relation to the standard dimensional specifications of a given cartridge,
normally in sets of three: "GO", "No-Go" and "Field". By loading these plug-gauges into the chamber in succession,
one can check that the action should close on the "Go" gauge. It should not close on the "No-Go" gauge,
but might were enough force to be used. And, it absolutely should not close on the "Field" gauge.
Abbreviation for feet per second. A term used in expressing the velocity of a bullet.
A cartridge in which the base diameter is the same as the body diameter. The casing will normally have an extraction groove machined around it near the base,
creating a "rim" at the base that is the same diameter as the body diameter.
A strong spring which activates the striker or hammer of a firearm.
A state of readiness of a firearm. The hammer (or similar mechanism if there is no hammer) only needs to be released by the trigger to cause the gun to fire.
The part of a revolver's frame connecting the recoil shield to the barrel-mounting recess; adding considerable strength compared to that
of early black powder Colt revolvers, and providing a base for a rear sight.
A specialized facility designed for firearms practice.
