The Definition of Tap, Rack, Bang
Tap, Rack, Bang
The slang term for the procedure to clear a misfeed. To clear a misfeed, tap the base of the magazine firmly to be sure it is properly seated,
rack the slide to eject an empty case or feed a new round, and assess to
be sure your target still needs shooting. If it does, pull the trigger to create the bang.
19 Other Firearms Definitions You Need To Know
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.
A needle gun is a bolt-action firearm (the first known type of bolt action rifle) that has a needle-like firing pin, which can pass through fully self-contained (paper) cartridge case to strike a percussion cap at the bullet base.
The first experimental needle gun was designed by Jean Samuel Pauly, a Swiss gunsmith, in 1812.
The first mass-produced needle gun was invented by the German gunsmith Johann Nicolaus von Dreyse, who, beginning in 1824, had conducted multiple experiments, and in 1836 produced the first viable breech loading gun model using a complete cartridge .
The abbreviation for Automatic Colt Pistol.
It is commonly used to designate specific calibers, particularly those which were originally designed by John Moses Browning for the
Colt Firearms Company which are a type of rimless pistol cartridge designed mainly for use in semi-automatic pistols.
The most common ACP calibers are .25 ACP, .32 ACP, .380 ACP and .45 ACP.
A small metal explosive-filled cup which is placed over the nipple of a percussion firearm. As the cap is struck by the hammer, it explodes and sends a flame through the flashhole in the nipple to the main powder charge.
Also known as peep sights, range from the ghost ring sight, whose thin ring blurs to near invisibility (hence ghost), to target aperture sights that use large disks or other occluders with pinhole-sized apertures. In general, the thicker the ring, the more precise the sight, and the thinner the ring, the faster the sight.
Helical grooves in the barrel of a gun or firearm, which imparts a spin to a projectile around its long axis.
This spin serves to gyroscopically stabilize the projectile, improving its aerodynamic stability and accuracy.
Also spelled blueing.
A passivation process in which steel is partially protected against rust, and is named after the blue-black appearance of the resulting protective finish.
True gun bluing is an electrochemical conversion coating resulting from an oxidizing chemical reaction with iron on the surface selectively forming magnetite
(Fe3O4), the black oxide of iron, which occupies the same volume as metallic iron. Bluing is most commonly used by gun manufacturers, gunsmiths and gun
owners to improve the cosmetic appearance of, and provide a measure of corrosion resistance to, their firearms.
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.
A quad stack box magazine.
An oversized, lightweight housing that allows a sub-calibre projectile to be fired in a larger-diameter bore, usually in the interest of increased velocity.
The sabot falls away from the actual projectile upon exiting the muzzle.
For example, a hunter could use his .30-30 deer rifle to shoot small game with .22 centerfire bullets.
A flat piece of rubber which holds revolver cartridges preparatory to loading them into the revolver's cylinder. Similar to a moon clip
Also known as collimating sight or occluded eye gunsight, a Collimator Sight is
a type of optical "blind" sight that allows the user looking into it to see an illuminated aiming point aligned
with the device the sight is attached to regardless of eye position (parallax free).
The user can not see through the sight so it is used with both eyes open while one looks into the sight,
with one eye open and moving the head to alternately see the sight and then at the target, or using one
eye to partially see the sight and target at the same time.
A metal, usually copper, wrapped around a lead core to form a bullet.
Skirted projectiles used in pellet guns
A small lever mounted to the cocking piece of a Winchester Model 70 rifle, rotating on a vertical axis from front (Fire),
halfway back (Safe, but allowing bolt movement), and fully back (Bolt and firing pin locked Safe).
While, like the Mauser, commendable for locking the firing pin instead of just the trigger,
its fore and aft movement is both easier to operate and it allows lower mounting of telescopic sights,
reducing parallax between the line of sight and the line of the bore and increasing the range of
distances for which the scope may be reliably sighted-in.
A second, folding or pop-up front sight bead of larger than usual size, perhaps not as accurate as a normal fine bead, but easier to see in the gloaming (twilight) or dawn.
A firearm manufactured by someone who is not a regular maker of firearms.
The part of the gun that strikes either the firing pin or the round directly when the trigger is pulled then detonates the primer of the load and discharges the gun. Hammers may be external or internal. On a striker fired gun (a gun without a physical hammer) the firing pin is considered the hammer since it releases directly when the trigger is pulled.
