Product Details

USGI Type M16 Bolt Carrier Group

Carbonite Black is a proprietary surface finishing process that is an evolution of traditional nitriding. While keeping all of the known benefits of nitriding, Carbonite Black leaves a highly polished final surface that seals the micro fissures found on all steel components.  This ensures not only a stronger final layer but increases the inherent lubricity, corrosion resistance and increased operational load bearing of the part.  This is an evolution of our Gen 1 Carbonite.
Compatible with all mil-spec AR15/M4 upper receivers, the Leitner-Wise®  Bolt Carrier Group is a precision manufactured sub-assembly that will improve the reliability and consistency of your host weapon.  The carrier is manufactured from precision ground heat treated 8620 steel and has an S7 gas key secured by Colt specification M16 screws and staked to 3,500ft/lbs.  The bolt is C158 steel, ground between centers to ensure absolute concentricity.  Tool steel extractor, arrow marked cam pin, M67 solid firing pin retain pin and precision ground stainless steel firing pin completes the package.  
  • Shot peened
  • Precision ground between centers

The BCG is finished with our proprietary Carbonite™ Black diffused surface finish, resulting in superior corrosion resistance and enhanced lubricity meaning no running in. Carbonate™ Black is an enhanced development of our Carbonite™ surface treatment.
