Action Assembly: |
Contains the moving parts which load the gun. |
Actions: |
Firearms are generally classified by their type of action. There are five basic types of action: bolt action, pump action,
lever action, hinge action and semi-automatic action.
|
Aperture Sight: |
A firearm sight that contains a small hole that a shooter peeps through to aim at the target. |
Barrel Assembly: |
The metal tube through which the bullet or shot travels when the gun is fired. |
Calibre: |
The inside diameter of the barrel before the rifling has been cut, usually expressed in hundredths of an inch or in millimetres.
For example, a .22 calibre barrel measures 22/100 of an inch in diameter.
|
Open Sight: |
A firearm sight that works by aligning an open rear sight and a front bead sight on a target. |
Rifling: |
A series of grooves that twist through the barrel. Rifling makes the bullet spin as it leaves the gun, making it more stable
in flight and therefore more accurate.
|
Safety: |
The safety locks the trigger and blocks the gun’s action so it cannot be fired. |
Scope Sight: |
A firearm sight that includes a mini telescope which is mounted on the rifle. |
Shotgun Choke: |
The narrowing found at the muzzle end of most shotgun barrels. The choke controls the pattern or spread of the shot and
determines the distance at which the shotgun will be most effective.
|
Shotgun Gauge: |
Shotgun barrels are classified by gauge instead of calibre. The gauge is the number of lead balls it takes to reach one
pound. Each ball is the same diameter as the bore. For example, a 12 gauge shot gun accepts 12 lead balls that together
weigh one pound.
|
Sight: |
A device used to aim a firearm. There are three basic types of sights: open, aperture and scope. |
Stock Assembly: |
The handle of the firearm. |
