The SOLGW Scalper Bolt Carrier Group is a full-auto / M16-profile BCG for the AR-15 in .223/5.56. The carrier is machined from 8620 steel to the M16 (full-auto) profile, which adds carrier mass for more consistent cycling. It is high-pressure tested (HPT) and magnetic-particle inspected (MPI), finished in black nitride, with a properly staked gas key.
Features:
The full-auto profile carrier is legal in semi-automatic rifles and adds mass for reliable cycling. Confirm gas system and caliber compatibility with your build before installing.
