Letter CThe Definition of Co-Witness Sighting
Co-Witness Sighting
Co-Witness Sighting is the use of any iron sight mounted onto a rifle that is fitted with an optical sight as a primary sighting system.
They come in two basic configurations, fixed or flip-up. The idea is that if you align your red dot and your iron
sights you have a backup aiming system on the gun.
19 Other Firearms Definitions You Need To Know
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 moon clip is a ring-shaped or star-shaped piece of metal designed to hold multiple cartridges together as a unit, for simultaneous insertion and extraction from a revolver cylinder.
Unlike a speedloader, a moon clip remains in place during firing, and after firing, is used to extract the empty cartridge cases.
German for a short rifle or carbine.
A rod, for loading and/or cleaning a muzzle-loading
firearm (usually a pistol) that is permanently connected to the gun by some sort
of swivel, so as to be easily utilized, but never lost.
An uncomfortable sensation caused by the trigger springing back into the shooter's trigger finger while firing.
Covered compartment in the buttstock of a rifle used to carry patches or other small items.
A magnifying tube through which the shooter may see the target and aim the firearm. Scopes contain a reticle, commonly in the shape of a cross, which must be properly centered upon the target for accurate aim.
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 eye protection. Referes to either goggles or safety glasses
a type of fighting in which small units engage the enemy with personal weapons at very short range,
potentially to the point of hand-to-hand combat or fighting with hand weapons such as swords or knives.
An offset of a gun stock to the left, so
that the line of sight aligns comfortably with the left eye while the butt of the stock
rests comfortably on the left shoulder. Almost all left-handed shooters benefit from a
little caston and most custom built guns are made this way. The only question is how
much. The caston of a gun is about right when, with the gun comfortably mounted, the
front bead lines up with the center of the standing breech.
A stock offset to the right, for shooting from the right shoulder is said to be
Holding the trigger to the rear after the shot has fired, until the sights are back on target, at which time the trigger is released.
The correct technical term for the ability of a projectile to incapacitate an animal or human shot with a firearm. Incorrectly called Stopping Power.
The amount of work done by a bullet, expressed in foot pounds.
The amount of change in the bore axis, measured both vertically and horizontally, while the projectile moves from the chamber to the muzzle when it is fired.
The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF, BATF, and BATFE) is a federal law enforcement organization within the United States Department of Justice. Its responsibilities include the investigation and prevention of federal offenses involving the unlawful use, manufacture, and possession of firearms and explosives; acts of arson and bombings; and illegal trafficking of alcohol and tobacco products. The ATF also regulates via licensing the sale, possession, and transportation of firearms, ammunition, and explosives in interstate commerce. Many of ATF's activities are carried out in conjunction with task forces made up of state and local law enforcement officers, such as Project Safe Neighborhoods. ATF operates a unique fire research laboratory in Beltsville, Maryland, where full-scale mock-ups of criminal arson can be reconstructed.
An action type that when the trigger of a gun is pulled, the gun gets cocked and the hammer (or striker) is dropped.
This applies to both revolvers and semi-automatic guns.
On a double action revolver, when the trigger is pulled, the hammer is cocked before releasing.
With a double-action semi-automatic pistol, the hammer does not have to be manually cocked (via actually pulling back the trigger or tracking the slide), the hammer (or striker) will be cocked while the trigger is being pulled.
A firearm that only the hammer drops when the trigger is pulled is a single action gun.
German for Hand-Cocking or Cocker/De-Cocker. A type of action on a break-open gun or rifle where, in place of a traditional top tang safety,
a somewhat more robust tab is fitted. Normally such a gun is carried in the field loaded, but with the action not cocked,
an exceedingly safe condition. Then, when ready to fire, the shooter, instead of pushing a safety tab forward,
pushes this larger tab forward, cocking the mainspring, making the gun ready to fire.
Then, if the shot is not taken, he may simply slide this tab rearwards again, de-cocking the gun
and returning it to the still-loaded, but very safe position.
