Frequently Asked Questions

What are the main parts of a firearm?

The main parts of a firearm include the stock (buttstock and fore end), the barrel, the action (moving parts including the trigger and safety), and the sights used for aiming. Understanding these components is fundamental to safe and effective firearm handling.

How does a firearm fire a cartridge?

When the trigger is pulled, it releases a firing pin that strikes the primer of the cartridge. This ignites the gunpowder, creating a controlled explosion that propels the bullet or shot out of the barrel.

What are the components of a rifle cartridge?

A rifle cartridge consists of a bullet (the projectile), a metallic cartridge case, gunpowder (the propellant), and a primer (the ignition source at the base).

What is the difference between caliber and gauge?

Caliber is used to describe the diameter of a rifle's bore or projectile, while gauge is used for shotguns, indicating bore size with lower numbers meaning larger bores. These terms are not interchangeable and denote different firearm sizes.
