AT M16 Enhanced Nitride BCG

This is our enhanced M16 Bolt Carrier Group which has several enhancements above our regular M16 Bolt Carrier Group. Most importantly, this carrier is designed to reduce carrier tilt/cant during recoil and increases reliability by strategically relocating key bearing surfaces. The enhanced carrier has fewer points of contact resulting in less friction area. The slight increase in carrier mass extends dwell time and ensures proper gas pressures for reliable extraction. The carrier is case-hardened 8620 steel, which is salt-bath-nitrocarburized for its nice black nitride coating. The gas keys are 4130 steel and properly staked per Mil-Spec. These are proudly made in the USA, and feature a laser engraved Allstar Tactical logo.
