The Definition of Suppressor
Incorrectoly sometimes referred to as a silencer, it is used to reduce the sound of a firearm's discharge.
They do not actually silence most firearms but rather lower the intensity of the muzzle blast and change the sound characteristics
(works similarly to an automotive muffler by disrupting and spreading out the sound waves).
The possession, use, and transportation of silencers have been tightly controlled under federal law since 1934.
Any device which reduces the sound of discharge by more than 2 dB is considered by the BATF to be a suppressor.
19 Other Firearms Definitions You Need To Know
Sometimes spelled Quad Rail.
First conceived and sold by Knights Armament Company in the mid 90s when Reed Knight saw soldiers duct taping flashlights to their handguards in news footage of Panama, the quad rail has become almost a standard item found on most military rifles. Quad rails allow easy attachment of accessories which aid tactical shooters, such as lights, infrared lasers, foregrips, sling attachment points, and secondary sighting systems.
However, nowadays, any full length forearms on an AR, with or without rails may also be refered to as a Quadrail.
A stout flange, invariably incorporated into the underside of the front receiver ring of a bolt action, and also frequently
incorporated into the underside of the barrel of a heavily-recoiling rifle, which when properly bedded, transfers recoil to the stock.
A second sear, poised just behind a second notch in the hammer. It is possible that when a cocked firearm is dropped or sharply jarred, a
single sear could jump out of its notch and the hammer could fall, firing the gun accidentally. In this event, an intercepting sear
would engage before the hammer could fall completely, preventing an accidental discharge. On a gun with intercepting sears, only
by pulling the trigger are both sears moved out of the way simultaneously, allowing the gun to fire.
Intercepting sears are usually found on better sidelock actions. They are sometimes found on best boxlocks,
and can be recognized by an extra screw behind the action fences, in addition to the usual two screws (or pins) along the lower rear of the receiver.
Gun Control Act of 1968.
It is a U.S. federal law that regulates the firearms industry and firearms owners. It primarily focuses on regulating interstate commerce in firearms by
generally prohibiting interstate firearms transfers except among licensed manufacturers, dealers and importers.
It also prohibits all convicted felons, drug users and the mentally ill from buying guns amd raised the age to purchase handguns from a federally licensed dealer to 21.
Slang for a gun or the action of carrying a gun concealed, e.g "The Bersa Thunder .380 is a fantastic gun for carrying" or "Do you carry?".
A feature on some guns which allows various aftermarket accessories to be attached the firearm such as flashlights or lasers.
On pistols, if equipped, the rail is on the underside of the frame below the barrel.
On rifles, a rain can be found above or below the barrel, with AR type rifles, the forestock can be made of rails allowing all kinds of attachments in various positions.
Nickname for the U.S. M1841 Rifle, a .54 caliber muzzleloading rifle. The name comes from their use by a group of U.S.
Volunteers from Mississippi who were commanded by Jefferson Davis in the Mexican War. Some were later rebored to .58 caliber.
A process of filling gaps between the action and the stock of a rifle with an epoxy based material.
An inert ammunition-shaped object, used in practice to simulate misfeeds and other malfunctions. Some folks also use them during dry fire practice to cushion the firing pin as it strikes.
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 unit of measure traditionally used for black powder shotgun charges. Today, used for smokeless powders on the basis of the new propellant's
equivalent performance to that weight of black powder. Thus, a shotgun shell marked 3 - 1 1/8
would be loaded with the smokeless powder equivalent of 3 drams of black powder, and with 1 ounce of shot. 1 Dram = 1/16 ounce = 437.5 grains.
A floppy, limp wrist while shooting.
Usually referred to as a Kentucky Long Rifle or simply Longrifle, the Kentucky Rifle is a flintlock rifle with a long barrel and short, crooked stock. It is widely believed to be a largely unique development of American rifles that was uncommon in European rifles of the same period.
The Kentucky Long Rifleis an early example of a firearm using rifling, (spiral grooves in the bore). This gave the projectile, commonly a round lead ball, a spiraling motion, increasing the stability of the trajectory.
Rifled firearms saw their first major combat usage in the American colonies during the Seven Years war, and later the American Revolution in the eighteenth century.
That part of the stock on a rifle or shotgun into which the barrel fits.
The size of the pellets in a shotgun shell.
A screw with about half of its threading removed in longitudinal sections. Often used at the breech end of a
takedown firearm's barrel. When the barrel's interrupted female threads are inserted into the receiver's
complementary interrupted male threads, only a partial rotation is necessary for assembly rather than many full turns.
A safety catch fitted to a hammer gun where a sliding bar moves into a slot in the inner wall of the hammer base, locking it in place in the cocked position.
The safety can then be released silently by sliding the tab, avoiding the game-startling sound of the hammer cocking.
A semi-automatic pistol in which the barrel and breechblock are locked together for the full distance of rearward recoil travel,
after which the barrel returns forward, while the breechblock is held back. After the barrel has fully returned,
the breechblock is released to fly forward, chambering a fresh round in the process.
