Module 3: FIREARMS
(Part 1) The different parts of a firearm.
The safe use of firearms requires a working knowledge of the firearm.
For example, if you are unsure how the safety operates, you may be placing yourself and others in an unsafe situation.
-
Stock - this is generally made of wood or a synthetic material. It is the portion of the firearm that is held by the person firing it.
(see image 1)
-
Butt (of a stock) – this is the contact point of the stock when the stock is placed against the shoulder.
-
Barrel – a steel tube that provides the initial guidance to a bullet or shot so that it gets to its target. (see image 2)
-
Fore-end – the front part of the stock. (see image 3)
-
Receiver or action – the mechanism of a gun involving the loading and firing of a cartridge and the ejection of a spent shell. (see image 4)
-
Chamber – the portion of the barrel where a cartridge is placed prior to being fired. This is a high pressure containment area that is precisely aligned with the bore of the barrel. A firearm cannot be fired when the chamber is empty.
-
Magazine – a storage device, detachable or integral, in a gun for holding and feeding ammunition. Magazines may be built in, detachable or tubular. (see image 5)
-
Muzzle – the end of the barrel where the bullet or shot departs.
-
Trigger – a small curved part that activates the firing mechanism of a gun to fire a cartridge.
-
Trigger guard – the protecting ‘loop’ that surrounds the trigger and prevents unintentional pulling of the trigger.
-
Safety – a mechanism that helps prevents accidental discharge of a firearm, ensuring safe handling. (see image 6)
