What is referred to as the stock of a firearm?

The stock of a firearm refers to the part of the gun that is held or braced against the shooter's body. It serves as the frame that supports the action of the firearm and helps stabilize it during firing. The stock allows the shooter to maintain control and aim accurately while absorbing the recoil generated when the firearm is discharged. A well-designed stock can enhance a shooter's comfort and precision.

In contrast, the other components mentioned serve different purposes in the operation and use of a firearm. The part that is fired is typically the barrel, through which the projectile exits. The part that you aim with usually refers to the sights or scope attached to the firearm, which aids in targeting. The trigger mechanism is the part that initiates the firing process when pulled. Each of these parts plays a crucial role in the overall function of the firearm, but the stock specifically relates to how the shooter holds and stabilizes the gun during use.
