The Definition of Falling Block
A type of action used primarily for single shot rifles whereby some kind of lever actuates a breechblock, moving it downwards in a vertical recess to expose the chamber.
May have visible or enclosed hammer. For any given barrel length, it allows a shorter overall rifle length compared to a bolt action because no space is
taken up by the forward-and-back cycling of the bolt. Most of the better British makers produced them in limited numbers around the turn of the last century,
the Farquharson being the most iconic. Perhaps the best-known falling block action today is the Ruger No.1.

Slang word abreviation for Ammunition.
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.
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.
Any piece of clothing that covers the holstered gun. When the gun is worn on the belt, the most common types of cover garments are vests, sweaters, and jackets.
The bottom of the butt-end of a gun stock.
A wildcat cartridge, or wildcat, is a custom cartridge for which ammunition and/or firearms are not mass-produced.
These cartridges are often created in order to optimize a certain performance characteristic (such as the power, size or efficiency) of an existing commercial cartridge.
Developing and using wildcat cartridges does not generally serve a purpose in military or law enforcement;
it is more a hobby for serious shooting, hunting, gunsmithing and handloading enthusiasts, particularly in the United States.
There are potentially endless amounts of different kinds of wildcat cartridges: one source of gunsmithing equipment has a library of over
6,000 different wildcat cartridges for which they produce equipment such as chamber reamers.
The open end of the barrel from which the projectile exits.
A large piece of curved metal at the top of the grip on a pistol which protects the user's hand from getting "bitten" by the hammer or slide.
It is nearly always the top part of the grip safety commonly found on many 1911-style pistols.
The angle of the butt of a gun in relation to the line of sight.
Pitch is measured by resting the gun with its butt flat on a floor, the top of the receiver against a wall and its muzzle pointing up.
The distance of the muzzle from the wall is the gun's pitch down.
A small metal cup that contains a tiny explosive charge that is sensitive to impact.
A primer is placed in the base of a shell casing to ignite the powder of the completed cartridge.
It is detonated by the striking of a firing pin in the firearm.
Skirted projectiles used in pellet guns
a non-magnifying gun sight that allows the user to look through a glass optical window and see a cross hair
reticle image superimposed at a distance on the field of view.
The hologram of the reticle is built into the window and is illuminated by a laser diode.
An external, manual safety which is typically disengaged with the firing-hand thumb.
A 1/60th part of a degree, the unit of measure used in adjusting rifle sights.
As it turns out conveniently, a minute of angle translates almost exactly to one inch at 100 yards
(actually 1.047 inches), to two inches at 200 yards and three inches at 300 yards
A firearm is a portable gun (pistol or rifle), being a barreled weapon that launches one or more projectiles often driven by the action of an explosive force.
A phenomenon which is often grouped with hammer bite. In this case the web of the shooting hand is cut or abraded by
the rearward motion of the semi-automatic pistol's slide, not by the gun's hammer.
This most often occurs with small pistols like the Walther PPK and Walther TPH that have an abbreviated grip tang.
This problem is exacerbated by the sharp machining found on many firearms.
A chemical phosphate process developed during the second world war to provide an economical, durable and non-reflective surface finish to military firearms.
An imaginary straight line from the eye through the sights of a firearm to the target.
The area inside the bore nearest to the muzzle.
