Product Description

The Q LLC Two-Piece Bolt Carrier Group (BCG) redefines what an AR-platform BCG can be. Engineered for the 5.56x45mm NATO caliber, this innovative two-piece design separates the carrier into a Front-End and a Rear-End, each crafted for precision and longevity. The Front-End is machined from Maraging Stainless Steel and finished in Black Nitride for superior corrosion resistance, enhanced lubricity, and reduced friction. A SCAR-Cut on the front end actively works to prevent bolt bounce, improving reliability under rapid fire. The Rear-End is precision heat-treated bare stainless steel machined to Mil-Spec overall length. The Rear-End houses the firing pin directly, eliminating the need for a firing pin retaining pin and removing a common failure point altogether. The single-pin carrier retention system makes field stripping fast and intuitive. Every component included meets or exceeds Mil-Spec: Mil-Spec Gas Key and Staking, Mil-Spec Bolt, Mil-Spec Cam Pin, and Mil-Spec Firing Pin. This is a BCG built not just to pass inspection, but to outperform in the field.

Product Highlights

  • Innovative Two-Piece Design: The BCG is split into a Front-End and Rear-End, manufactured on modern equipment with modern materials for tighter tolerances and easier quality control.
  • Maraging Stainless Steel Front-End with Black Nitride Finish: Provides exceptional hardness, corrosion resistance, and a self-lubricating surface that reduces wear and simplifies maintenance.
  • SCAR-Cut Front-End: Engineered cut on the front section prevents bolt bounce during cycling, improving consistency and reliability under high-volume fire.
  • No Firing Pin Retaining Pin: The Rear-End holds the firing pin directly, eliminating a common failure point and streamlining field maintenance.
  • Full Mil-Spec Components: Includes Mil-Spec Gas Key with proper staking, Mil-Spec Bolt, Mil-Spec Cam Pin, and Mil-Spec Firing Pin, exceeding standard military specifications throughout.
