The AR-STONER bolt carrier group for the LR-308 platform features a black nitride finish for enhanced wear resistance. The carrier is machined from 8620 steel, while the 308 Winchester bolt is machined from 9310 steel and shot-peened. This BCG includes a properly staked forged gas key, an S7 tool steel extractor with a heavy-duty spring, and Grade 8 hardware. It is HPT/MPI tested and ready for drop-in installation, though headspace should be verified by a qualified gunsmith upon assembly.
