The Definition of Field Gun
A shotgun, generally stocked to shoot where it is pointed and of relatively light weight because one often carries it a great distance for upland birds,
the consequent recoil not being an important factor because one actually shoots it very little.

Head [of a Stock]. The forward end of a buttstock, where it meets the receiver and accepts the bulk of the gun's recoil when fired.
A military person designated as a special marksman who is used to shoot designated targets of opportunity at long range.
A bore snake is a tool used to clean the inside (bore) of the barrel of a gun. It resembles a short section of rope with a smaller,
weighted cord attached to one end to help feed the bore snake through the barrel. A bore snake often has one or more integrated brushes to help clean the barrel,
and may also be used to apply lubricant. It is an alternative to using a cleaning rod and patches to clean the barrel of a gun.
Bore snakes are made in different sizes for different calibers and gauges of guns.
The entire collection of moving parts which work together to fire the gun when the trigger is pulled.
It may include trigger springs, return springs, the trigger itself, the sear, disconnectors, and other parts.
Refers to a visible dark ring created by the primers in centerfire ammunition around the firing pin hole in the frame after much use.
A highly sensitive explosive used as a primer compound.
A name for any palm sized handgun which fires a small caliber.
The beginning of the bore of a rifled firearm. The transition between the chamber and the rifling. The area most vulnerable to erosion from high velocity cartridges.
Abbreviation for Double Action Only. Is a type of firearm in which the firing mechanism cannot be cocked in a single-action stage. Firing always occurs as a double-action sequence where pulling the trigger both cocks and then fires the gun.
A unit of measure traditionally used for black powder shotgun charges. Today, used for smokeless powders on the basis of the new propellant's
equivalent performance to that weight of black powder. Thus, a shotgun shell marked 3 - 1 1/8
would be loaded with the smokeless powder equivalent of 3 drams of black powder, and with 1 ounce of shot. 1 Dram = 1/16 ounce = 437.5 grains.
An offset of a gun stock to the right, so
that the line of sight aligns comfortably with the right eye while the butt of the stock
rests comfortably on the right shoulder. Almost all right-handed shooters benefit from a
little castoff and most custom built guns are made this way. The only question is how
much. The castoff 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 left, for shooting from the left shoulder is said to be
This means a shooter who is right-handed but left-eyed, or left-handed and right-eyed.
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.
The premier bolt action, whose design by Paul Mauser coalesced in 1898,
and from which were derived the Springfield 1903, the Winchester Model 70 and many others.
A hinged plate covering the bottom of a rifle magazine and extending rearward on either side of the triggerguard.
This design allows it to be more securely fastened for one more imperceptible step towards total reliability.
A semi-automatic is said to be out of battery when the slide fails to come all the way forward again after the
gun has fired. This condition can be created by a misfeed, a dirty gun, weak springs, the shooter's
thumbs brushing against the slide, riding the slide, or any of several other causes.
The small lever on a cartridge firearm, which one pulls to cause the spring-loaded firing pin to impact the primer, causing the gun to discharge.
Normally, the trigger simply connects to the sear. Pulling the trigger moves the sear out of its notch, releasing the spring-loaded hammer
to strike the firing pin which in turn strikes the primer; or the coilspring-loaded firing pin directly. Other, often-Germanic systems have their own
miniature lockwork which, when cocked, allows an exceedingly light trigger pull to discharge the firearm, a setting that would be perilous to carry in the field.
Not really a gun at all. During the U.S. Civil War,
both sides would take tree branches or tree trunks, paint them black, and position them so that they appeared to be rifles or artillery pieces.
By doing so, they could fool the other side into believing that they had more artillery than they really did.
