The Two-Piece Bolt Carrier Group.

The Two Piece BCG is designed to be manufactured on modern equipment using modern materials. 

Q's BCG consists of 2 sections; The Front-End and The Ass-End

The front end is made up of Maraging Stainless Steel dressed in black with a Nitride Coating and is SCAR-Cut to help prevent bolt bounce. 

Standard with:

• Mil-Spec Gas Key and Staking
• Mil-Spec Bolt
• Mil-Spec Cam Pin
• Mil-Spec Firing Pin

The Ass-End is naked Stainless Steel heat treated of course and yes the overall length is Mil-Spec.

The Ass-End holds the firing pin doing away with pesky firing pin retaining pins. No more broken pins. You're welcome. 

The Carrier is retained with a single Pin allowing for easy field stripping.
