CMC Triggers Enhanced Bolt Carrier Group – Suppressor Optimized, Mil-Spec, Nitride – 6mm ARC

At Ally Munitions, quality is our top priority. Every CMC Triggers Enhanced Bolt Carrier Group (BCG) we offer has been visually inspected by Wade before it's listed for sale. We've spent over two years rigorously testing this exact BCG across various suppressed and unsuppressed platforms, and it has earned our full endorsement.

Built for shooters who expect reliability under pressure, this BCG is optimized for suppressor use and short-barreled rifles. It combines precision machining, upgraded materials, and a thoughtful design to ensure smoother cycling, cleaner operation, and longer component life.
