CMC Triggers AR-15 Bolt Carrier Group 6mm ARC

The CMC Triggers AR-15 Bolt Carrier Group 6mm ARC is engineered for modular compatibility with AR-15 platforms chambered in 6mm ARC. Its design supports integration with a range of AR-15 upper receivers, making it suitable for builds that require reliable cycling and enhanced extraction, especially when using suppressors or short-barreled rifles.

This bolt carrier group features a flared rear to minimize carrier tilt and cant during recoil, improving reliability by optimizing bearing surface placement. The carrier is constructed from case-hardened 8620 steel, while the bolt is made from 9310 case-hardened steel and CNC ground after heat treatment for a precise fit. The "trumpet" area behind the gas rings is also CNC ground for easier cleaning and increased longevity.
