AR Parts: Bolt Carrier Group

Bolt Carrier Group

Building your own AR 15 provides countless options. This includes the choosing to either purchase a pre-assembled bolt carrier group or assemble your own. Assembling the carrier group on your own allows you to choose the options that benefit you the most.

The bolt carrier group is one of the most important parts of the AR-15. Consisting of the bolt carrier, bolt, firing pin, cam pin, ejector, and gas rings, the carrier group is the heart of the AR’s direct impingement system.

Bolt carrier groups can be customized based upon budget and preference. Make sure when purchasing a bolt carrier group that it is designed to work with your specific caliber. If you have questions regarding what bolt or assembly is correct, please check with the manufacturer.

Remember if assembling your own bolt carrier group that it is necessary to check the headspace before firing the firearm. Too little or too much headspace can cause serious injury to both you and the firearm. Checking headspace is a must.

When assembling your AR-15 for the first time you may have some questions. Feel free to contact us with any questions you might have. We look forward to helping you in any way we can.
