CMC Triggers Enhanced 6mm ARC AR-15 Bolt Carrier Group - Nitride

The CMC Triggers Enhanced Bolt Carrier Group has been expertly designed to increase the life and reliability of an AR rifle. Its geometry reduces friction points against the upper receiver, reducing wear and making the action feel smoother.

Features:

• M16 cut carrier with flared end, reduces carrier tilt
• Chambered in 6mm ARC
• 9310 steel bolt, shot peened
• 8620 steel carrier
• Salt bath nitride finish
• Enlarged forward gas ports, optimized for suppressor use
• Hardened 4340 cam pin
• Mil-Spec 8740 steel firing pin
• Mil-Spec extractor spring and O-ring
• High pressure tested and magnetic particle inspected

The M16 cut's flared end increases weight for use with SBRs or suppressed rifles while decreasing carrier tilt. Every surface is CNC ground after heat treating to ensure precise dimensions with the highest possible tolerances, and the salt bath nitride finish increases lubricity and hardness for longer intervals between cleanings.

With roots in aerospace manufacturing, CMC is perhaps best known as the producer of the original drop-in precision trigger for the AR-15/10 platform. CMC Triggers are dedicated to crafting the finest parts and accessories for law enforcement, military, and civilian use.
