Bolt Carrier Groups

Bolt Carrier Groups

The Bolt Carrier Group is the heart of your firearm, and is responsible for housing the bolt and resetting the hammer, as well as bearing the majority of the gas pressure with each shot. Having a quality bolt carrier is crucial for a smooth, reliable operation, and differences in weight, platings, coatings, and even firing-pin hole size change how your gun fires. Check out the different BCG configurations. Make sure you're getting the best performance from your firearm with the best bolt carrier groups offered by ACME Machine.
