How does a AR-15 operate?
The AR-15 fires from a locked bolt, meaning that when a cartridge is chambered, the bolt closes behind the case and rotates 15 degrees: the lugs on the bolt head engage the protrusions on the barrel extension, solidly locking the bolt in place, so it can withstand the high pressure produced by powder combustion.
How many parts are in a AR-15?
To assemble the AR-15 stripped lower, you will need 31 different parts, including the trigger, bolt catch, springs, pivot and takedown down pins, selector switch and hammer. The most convenient way to get all of these parts is by purchasing a full AR-15 lower parts kit.
What is the barrel cover on an AR-15 called?
A handguard is a type of (often only half-length) barrel shrouding that is designed specifically for the user to grip the front of the gun for better stability and control.
What is the button on the side of an AR for?
The forward assist on a firearm is a button found commonly on AR-15 rifle derivatives, such as the M16 rifle, and is usually located near the bolt closure. When hit, it pushes the bolt carrier forward, ensuring that the bolt is locked.
Where should I hold my AR-15?
Place your hand underneath the guard with your palm facing up and point your index finger toward the barrel’s end, without touching the barrel. Thumb placement is a matter of preference. You can place your thump alongside your palm or wrap it around the top of your rifle.

What is the difference between AR – 10 and AR – 15?
One of the most obvious differences between the AR-10 and the AR-15 is the caliber. The AR-10 utilizes the .308/7.62×51, while the AR-15 uses the .223/5.56 x 45 cartridge. The lower receiver and other key components on the AR-10 are also somewhat larger than on the AR-15, which accounts for the slightly heavier weight.
