From the manufacturer

The Brownells Complete .308 Bolt Carrier Group is designed to operate reliably in DPMS LR-308 pattern rifles chambered in .308, .243, 7mm-08, .338 Federal, .260 Remington, 6.5mm Creedmoor, or any other cartridge based on the .308 Winchester. These BCGs are manufactured to the same uncompromising standards as our M16-style BCGs. Our Complete .308 Bolt Carrier Group has a bolt machined from robust 9310 steel, heat-treated and shot-peened for superb hardness. The carrier itself is fabricated from hardened 8620 steel. Both are magnetic particle inspected (MPI) to make sure there are no hidden microscopic flaws that could lead to premature failure. Carrier has forward assist notch Mfg: Brownells
