The LANTAC M-SPEC .308 Bolt Carrier Group is a DPMS-pattern large-frame BCG built for shooters who want LANTAC manufacturing quality without stepping up to the company’s more specialized Enhanced BCG. Its increased-mass 8620 carrier is paired with an MPI-tested Carpenter 158 or 9310 bolt, while the QPQ nitride treatment provides a hard, low-friction surface that resists wear and corrosion. A polished CP-R360-H domed cam pin further reduces friction where the cam pin interfaces with the upper receiver.
Note: LANTAC specifies this BCG for DPMS-pattern .308 rifles. Large-frame AR components are not universally standardized, so do not assume compatibility with every rifle marketed as an AR-10 or .308 AR; verify the receiver and barrel extension pattern before installation.
