Caliber
In guns, particularly firearms, caliber (or calibre; sometimes abbreviated as "cal") is the specified nominal internal diameter of the gun barrel bore – regardless of how or where the bore is measured and whether the finished bore matches that specification.
Air gun
An air gun or airgun is a gun that fires projectiles pneumatically with compressed air or other gases that are mechanically pressurized without involving any chemical reactions, in contrast to a firearm, which pressurizes gases chemically via oxidation of combustible propellants that generates propulsive energy by breaking molecular bonds.
Muzzle velocity
Muzzle velocity is the speed of a projectile (bullet, pellet, slug, ball/shots or shell) with respect to the muzzle at the moment it leaves the end of a gun's barrel (i.e. the muzzle).
Cannon
Large-caliber gun classified as a type of artillery, and usually launches a projectile using explosive chemical propellant.
The word has been used to refer to a gun since 1326 in Italy, and 1418 in England.
Ranged weapon
Any weapon that can engage targets beyond hand-to-hand distance, i.e. at distances greater than the physical reach of the user holding the weapon itself.
After the invention of gunpowder and the development of firearms, gun-type pneumatic ranged weapons became the dominant weapon of choice in armed conflicts, even in close combat.
Gun barrel
A gun barrel is a crucial part of gun-type ranged weapons such as small firearms, artillery pieces and air guns.
Projectile
Object that is propelled by the application of an external force and then moves freely under the influence of gravity and air resistance.
Blowguns and pneumatic rifles use compressed gases, while most other guns and cannons utilize expanding gases liberated by sudden chemical reactions by propellants like smokeless powder.
Musket
Muzzle-loaded long gun that appeared as a smoothbore weapon in the early 16th century, at first as a heavier variant of the arquebus, capable of penetrating heavy armour.
However, P.E.P. Deraniyagala points out that the Sinhalese term for gun, 'bondikula', matches the Arabic term for gun, 'bunduk'.
Stock (firearms)
Also known as a shoulder stock, a buttstock or simply a butt, is a part of a long gun that provides structural support, to which the barrel, action, and firing mechanism are attached.
A butt hook, which is an attachment to the butt of the gun that is put under the shooter's arm to prevent the rifle from pivoting forward from the weight of the barrel is sometimes used in competitive rifle shooting.
