LANTAC Enhanced BCG 308/7.62 Black Nitride

Description

The LANTAC Enhanced Bolt Carrier Group is a precision-engineered carrier assembly for .308 / 7.62 NATO applications, built with durability and consistent cycling in mind. The carrier is machined from heat-treated 8620 steel and the bolt is shot-peened and MPI inspected, manufactured from Carpenter 158 or 9310. The entire carrier assembly receives a QPQ (quench polish quench) nitride coating for a hard, low-friction surface and improved corrosion resistance. This configuration is documented for DPMS Gen 1 pattern rifles and is compatible with both semi-auto and full-auto configured systems where applicable.
