The Definition of Federal Assault Weapons Ban
Federal Assault Weapons Ban
Part of the Violent Crime Control and Law Enforcement Act of 1994.
It produced a 10-year federal ban on the manufacture of new semi-automatic assault weapons with certian specifications.
Firearms with specific features were defined as assault rifles.
Including the AR-15, certain versions of the AK-47, the TEC-9, the MAC-10 and the Uzi,
several of which had become the preferred weapon of violent drug gangs. The act also bans large-capacity ammunition magazines, limiting them to 10 rounds.
The law did not apply to weapons that were already in legal possession.
Because this law was not renewed by congress in 2004, the ban was lifted.
19 Other Firearms Definitions You Need To Know
Can also be spelled Over/Under, OverUnder or Over and Under.
A firearm (most commonly a shotgun) with two barrels that are vertically aligned with each other, one on top of the other.
A pair of small dovetailed steel bases, screwed usually one to the barrel and one to the front receiver ring of a rifle,
to accept mounts for target scopes such as the Unertl where the scope is allowed to move forward in the rings under
the recoil of the rifle and which typically carry the windage and elevation adjustments in the mount.
A hollow base bullet, shaped so that, when fired, the bullet will expand and seal the bore.
It was invented by Captain John Norton of the British 34th Regiment in 1832, after he examined the blow pipe arrows used
by the natives in India and found that their base was formed of elastic locus pith, which by its expansion against the
inner surface of the blow pipe prevented the escape of air past it.
Slang for a full metal jacket bullet with a round nose.
The term is most commonly used in referring to .45 ACP caliber ammunition, but may be used for other calibers as well.
The length, within a rifled barrel, required to accomplish one full rotation. 1:12 Twist, means a bullet passing down the bore would complete one revolution in twelve inches.
1:7 Twist, means a bullet passing down the bore would complete one revolution in seven inches, which makes it a tighter twist than 1:12.
Different weights of bullet require appropriate rates of twist.
A small metal tube extending through the breech of a percussion firearm through which the flame passes from the percussion cap to fire the powder charge.
An unexpected delay between the triggering of a firearm and the ignition of the propellant.
This failure was common in firearm actions that relied on open primer pans, due to the poor or inconsistent quality of the powder.
Modern weapons are susceptible, particularly if the ammunition has been stored in an environment outside of the design specifications.
Reloaded ammunition may also be the cause if not reloaded properly
A matrix of dots, posts or lines, visible inside a rifle's telescopic sight, normally adjustable via exterior knobs for windage and elevation.
After careful adjustment at a known range, the shooter aims the rifle by superimposing this matrix onto the target. With good estimation or range,
cooperation from the wind, a clear eye and a steady hand, he may have a reasonable expectation of hitting his target.
The device that aids the eye in aiming the barrel of a firearm in the proper direction to hit a target.They can be a mechanical, optical,
or electronic device. Iron sights or sometimes as open sights, consist of specially-shaped pieces of metal placed at each end of the barrel.
The sight closest to the muzzle end of the gun is called the front sight,
while the one farthest from the muzzle (and nearest to the shooter) is called the rear sight.
A part in a firearm that serves to remove brass cases of fired ammunition after the ammunition has been fired.
When the gun's action cycles, the extractor lifts or removes the spent brass casing from the firing chamber.
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.
Also known as Gun Powder.
A mixture of sulfur, charcoal, and potassium nitrate. It burns rapidly, producing a volume of hot gas made up of carbon dioxide, water, and nitrogen, and a solid residue of potassium sulfide.
Because of its burning properties and the amount of heat and gas volume that it generates, gunpowder has been widely used as a propellant in firearms and as a
pyrotechnic composition in fireworks.
Modern firearms do not use the traditional black powder described here, but instead use smokeless powder.
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.
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.
A fully automatic firearm that rapidly fires multiple rifle-caliber shots with a single pull of the trigger.
On a revolver, a spring activated device housed in the bottom of the frame beneath the cylinder that engages alignment notches in the cylinder.
It stops the cylinder's rotation and holds it in place each time a chamber in the cylinder is in alignment with the barrel.
An armor-piercing shell must withstand the shock of punching through armor plating. Shells designed for this purpose
have a greatly strengthened case with a specially hardened and shaped nose,
and a much smaller bursting charge.
The propellant powder used in modern ammunition. It is not an explosive, but rather a flammable solid that burns extremely rapidly releasing a
large volume of gas. Commonly called "gunpowder" and usually made from nitrocellulose, or nitrocellulose and nitroglycerin.
It is classified as a "Flammable Solid" by the Department of Transportation.
