19 Best Bolt Carrier Group For 556 (2022 Updated)

A bolt carrier group (BCG) is a critical, and often misunderstood, component of an AR-15 rifle. The BCG is a metal housing that contains the bolt and bolt carrier, and is responsible for moving the round from the magazine into the chamber and then locking the round into the barrel.

The BCG also contains the firing pin, which strikes the primer of the round, igniting the powder and sending the bullet down the barrel.

The BCG is the “heart” of the AR-15 rifle and is what makes it function. It is important to choose a BCG that is of high quality and well-made, as this will ensure that your rifle functions properly and reliably.

There are many different brands and types of BCGs on the market, so it is important to do your research and choose one that will work best for your specific rifle and needs.
