19 Other Firearms Definitions You Need To Know
The distance that equates the exit pupil size of a rifle scope's
ocular lens to the entrance pupil of the user, in order to achieve the largest, unvignetted view.
This distance must be sufficient to ensure that the ocular rim of the scope does not lacerate the shooter's
eyebrow upon recoil. And, the scope should be positioned so that eye relief is suitable when the rifle is comfortably mounted.
An established place where firearms and ammunition are stored, repaired, or manufactured.
The term is misused by the media to mean more than one firearm or any quantity of ammunition, as in "they found an arsenal."
Barrel tubes built up by twisting alternate strips of iron and steel around a fixed rod (mandrel) and forge-welding them together in varying combinations
according to the intended quality and the skill of the maker. The rod was withdrawn, the interior reamed and the exterior filed until the finished tube was achieved.
Damascus barrels may be recognized by any of a variety of twist or spiral patterns visible in the surface of the steel.
Before the 20th century, barrels were typically built in this manner because gunmakers did not have the technology to drill
a deep hole the full length of a bar of steel without coming out the side.
A device fitted inside the buttstock of a heavily-recoiling gun or rifle, usually containing mercury and a valve.
As the gun recoils, the mercury is displaced temporarily, increasing the duration, and thus diminishing the
perceived impact of the recoil. The added half-pound of weight doesn't hurt either.
A type of firearm in which the action is closed, with a cartridge in the chamber prior to firing. When the trigger is pressed the cartridge is fired,
and the action cycles loading another cartridge into chamber and when firing is stopped the bolt remains closed and the chamber remains loaded.
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.
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.
A bullet that is designed to disintegrate into tiny particles upon impact to minimize their penetration for reasons of range safety,
to limit environmental impact, or to limit the danger behind the intended target. Examples are the Glaser Safety Slug and the breaching round.
In a shotgun barrel, A tapered area a few inches from the breech end, providing a transition between the chamber
(approximately the diameter of the outside of a shotgun shell) to the bore proper (approximately the diameter of the inside of a shotgun shell).
The forcing cone provides the transition between the exterior and the interior diameters of the cartridge.
Older shotguns usually have more abrupt forcing cones suitable for then-current thick-walled paper shells with fibre wads.
Newer shotguns usually have more gradual, longer forcing cones suitable for thinner modern plastic shells with obturating plastic shot-cup wads.
On a pump-action firearm, being too gentle with the fore-end and either not pulling it all the way back at the beginning of the stroke,
or not shoving it all the way forward at the end of the stroke. Which may result in the old case or shell failing to eject and a misfeeds, or the gun
will not fire when the trigger is pulled. The term is used most often to refer to pump-action shotguns, but it is possible to similarly short-stroke any type of
firearm which requires the user to manually cycle the action (lever action rifles, for example).
A firearm with a coil-spring-actuated firing pin, or with its hammer enclosed inside the action body; i.e.. no externally visible hammer.
A compartment built into the buttstock of a long gun,
usually with a hinged cover, in which are drilled holes deep enough to hold
several spare cartridges of the type suitable for use in the specific gun.
Generally refers to the stock and fore-end of a rifle. Can sometimes also be applied to any detachable accessories like a flashlight.
A mark within a border, typically
stamped into the wood, especially of an American military rifle. It shows the
initials of the name of the accepting inspector and often, the date he accepted
the firearm into service.
The open end of the barrel from which the projectile exits.
The hinged cover over the opening through which cartridges are inserted into the magazine.
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.
A firearm is loaded when a cartridge is in its firing chamber. However, for safety reasons all firearms are always treated as loaded at all times.
An empty ammunition case.
