19 Other Firearms Definitions You Need To Know
An attachment to or integral part of the barrel that redirects some of the pressurized gas that propelled the bullet out the muzzle to the sides and possibly rearwards from the direction of the bullet travel. This reduces the recoil of the firearm.
A charge of powder, a projectile or a cartridge. Also, to prepare a gun for firing by inserting ammunition into it.
A type of shotgun ammunition that uses medium-sized to large-sized pellets of .24" in diameter or greater, designed to be discharged in quantity from a shotgun. Generally the larger the pellets, the fewer of them there are in casing.
A type of firearm action which uses a lever located around the trigger guard area, (often including the trigger guard itself) to load fresh cartridges into the chamber of the barrel when the lever is worked.
A metal, usually copper, wrapped around a lead core to form a bullet.
Shooting a target at a very very close range.
Small caliber bullets being used in large cases. E.g. .22 bullet in a .45 acp case.
A volume of fire delivered by a military unit. Incorrectly used by the media to mean the ability of a small arm to be discharged many times without reloading.
A measure of projectiles ability to overcome air resistance in flight. It is inversely proportional to the deceleration—a high number indicates a low deceleration. Ballistic Coefficient (abbreviated as BC) is a function of mass, diameter, and drag coefficient. In bullets it refers to the amount that drop over distance and wind drift will affect the bullet.
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.
Abbreviation for Concealed Firearms Permit.
A set of holes in a target left by a succession of bullets fired from the same rifle or handgun, using the same ammunition and sight setting. Fired (within the limits of one's marksmanship ability) to determine the inherent accuracy of the rifle/ammunition combination, and to aid in the proper adjustment of the sights.
A bolt-action designed by Browning firearms. The x-bolt action features a short 60° bolt lift. So it is fast cycling and allows working the bolt quicker without the scope getting in the way.
Also known as a Flash Hider. A muzzle attachment intended to reduce visible muzzle flash caused by the burning propellant. Flash reducers lessen glare as seen by the shooter, but do not hide the flash from other observers to the front or side of the firearm.
Brady Handgun Violence Prevention Act of 1993. The Brady Handgun Violence Prevention Act of 1993 mandates background checks of gun buyers in order to prevent sales to people prohibited under the Gun Control Act of 1968 legislation. Requires checks to be performed through the FBI's National Instant Criminal Background Check System (NICS). Records of who has been checked are not preserved because federal law prohibits the creation of a national registry of gun ownership. Sales by unlicensed private sellers who are not engaged in gun dealing as a business are not subject to the checks under federal law, though they are required by some states.
One of the three major dismountable components of a break-open gun (the others being the barrel(s) and the action/buttstock) which secures the barrels to the receiver, often houses the ejector mechanism, and for some, provides a handle for the one's secondary hand.
A mechanical device to make it easier to fill magazines using less hand strength and without hurting one's fingertips or thumbs.
A slang term for a small inexpensive handgun. Saturday night specials have been defined as compact, inexpensive, small-caliber handguns with perceived low quality; however, there is no official definition of "Saturday night special" under federal law, though some states define "Saturday night specials" or "junk guns" by means of composition or materials strength. Low cost and high availability make these weapons attractive to many buyers despite their shortcomings.
The correct technical term for the ability of a projectile to incapacitate an animal or human shot with a firearm. Incorrectly called Stopping Power.
