Building or repairing an AR-15 chambered in 6.5 Grendel or 6mm ARC? The CMMG AR-15 Bolt Carrier Group is purpose-built for these intermediate cartridges and ready to handle the demands of precision rifle work. Whether you're assembling a long-range hunting rig or a match-grade AR, this bolt carrier group delivers the reliability and durability you expect from CMMG's commitment to quality parts.
The bolt carrier group is the heart of your AR's operation. This unit combines a 9310 steel bolt, an 8620 steel chrome-lined carrier, and a 4140 steel extractor—each component chosen for its material strength and engineered to work in concert. The phosphate finish throughout provides proven corrosion resistance and the matte appearance fits seamlessly into any build aesthetic.
If you're stepping up to 6.5 Grendel or 6mm ARC for extended-range capability, you need parts that won't compromise the platform's reliability. This BCG is specifically dimensioned for these cartridges, ensuring proper function and longevity across hundreds of rounds. Drop it into your lower receiver and get back to shooting.

This is a complete, ready-to-install bolt carrier group. It includes the bolt, carrier, and extractor—everything needed for immediate use in your AR-15 lower receiver.
The chrome lining on the carrier enhances corrosion resistance and reduces wear from thousands of rounds of fire, extending the service life of the component.
