The Definition of Hinge Pin
A short cylindrical rod of hardened steel running laterally near the front of the bar of a break-open gun's
action around which the barrel hook revolves when the gun is opened. Over the decades, this pin and its
complimentary hook can wear and a gun can sometimes "shoot loose" or "come off the face." The proper cure
for this condition is to replace the hinge pin with a new one, slightly oversized, to compensate for wear
on both itself and on the barrel hook.
19 Other Firearms Definitions You Need To Know
A shotgun, often with only a single relatively-long barrel, with relatively tight choke boring and a relatively high-combed stock used for shooting clay pigeons in the game of Trap,
where the birds are launched at least 16 yards ahead, usually rising and going away from the shooter at relatively low angular velocity.
To better absorb recoil, a trap gun is normally heavier than a field gun because one shoots a lot but walks only a little.
A muzzle flash is the visible light of a muzzle blast, which expels high temperature, high pressure gases from the muzzle of a firearm.
The blast and flash are caused by the combustion products of the gunpowder, and any remaining unburned powder,
mixing with the ambient air. The size and shape of the muzzle flash is dependent on the type of ammunition being
used and the individual characteristics of firearm and any devices attached to the muzzle (such as a muzzle brake or flash suppressor)
Any gun that can be used in a sport.
A strong spring which activates the striker or hammer of a firearm.
A handgun or rifle shooting sport in which the competitors attempt to knock over metallic game-shaped targets at various ranges.
A steel ring, around an inch in diameter, mounted to a stud, usually on the left side of the receiver of a carbine,
to which may be tied a leather thong to secure it to a saddle or a scabbard so as not to lose the carbine when riding a rambunctious horse.
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 chemical phosphate process developed during the second world war to provide an economical, durable and non-reflective surface finish to military firearms.
A sliding bar, running longitudinally through the watertable of a break-open side-by-side gun's action, with openings through which the
lumps of the barrels pass when the gun is closed. Under spring tension, this bar moves forward when the opening control is released and its
two locking surfaces engage complementary slots (bites) in the rear of the two barrel lumps. Originally operated by a hinged tab in front
of the trigger guard. Now invariably operated by a cam from Scott's [toplever] spindle. Most modern side-by-side guns lock closed in this manner.
The lock that preceded the 'true' flintlock in both rifles and pistols in the 17th century.
Commonly used throughout Europe in the 1600s, it gained popular favor in the British and Dutch military.
A doglock carbine was the principal weapon of the harquebusier, the most numerous type of cavalry in the armies of Thirty Years War and the English Civil War era.
In shotgunning, multiple pellets contained in the shell and sent downrange when the shotgun is fired.
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.
Usually a rifle, but not always.
A small-caliber firearm or high-powered air gun primarily used for hunting
non-native or non-game animals such as rats, squirrels, gophers, jackrabbits, marmots, groundhogs, porcupine, opossum, coyote, skunks, weasels,
and other animals considered to be nuisance vermin destructive to native or domestic plants and animals.
Front, metal, part of a handgun's grip, which together with the backstrap, provides a mounting frame for the grip panels.
A needle like metal part of a modern firearm that gives a vigorous strike to the primer initiating the firing of the cartridge.
The distance from the front trigger of a shotgun to the centre of the butt.
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.
The setting on the sights of a firearm that controls the vertical placement and the altitude above mean sea level.
This is important for long range precision shooting because the air density changes with elevation and affects the path of the bullet.
