CMC Triggers Enhanced Bolt Carrier Group 6mm ARC

CMC Triggers Enhanced Bolt Carrier Group for 6mm ARC

The CMC Triggers Enhanced Bolt Carrier Group represents a thoughtful engineering approach to the demands of modern rifle shooting. Designed specifically for the 6mm ARC cartridge, this component addresses the real-world challenges shooters face when running suppressors or short-barreled rifles.

Carrier Assembly

The enhanced carrier features a strategically flared rear design that reduces carrier tilt and cant during recoil—a critical factor in maintaining reliability under demanding conditions. Manufactured from Case-hardened 8620 steel, the carrier incorporates fewer contact points than standard designs, resulting in less friction and smoother operation.

The increased mass of this carrier ensures proper gas pressure management and extends dwell time, which proves invaluable when shooting suppressed or with short-barreled configurations. This design philosophy prioritizes extraction reliability when it matters most.

Bolt Assembly

The bolt maintains true Mil-spec dimensions with external surfaces CNC ground after heat treatment for precision fit and tight tolerances. The "trumpet" area behind the gas rings—where carbon naturally collects—receives precision CNC grinding after heat treatment to minimize buildup and simplify maintenance.

Manufactured from 9310 Case Hardened Steel, the bolt components undergo shot peening and Black Nitride coating for enhanced durability and corrosion resistance.

Key Features

• Black Nitride finish for corrosion resistance and easy cleaning
• Enlarged forward ports optimized for suppressor use
• Hardened 4340 cam pin for reliable operation
• Mil-Spec 8740 steel firing pin for consistent ignition
• MPI and HPT tested for quality assurance
• Mil-Spec Extractor Spring & O-Ring for reliable extraction
• 6mm ARC compatible for seamless integration

This is a component built for shooters who understand that reliability begins with precision engineering.
