The Odin Works AR-10 Bolt Carrier Group (Odin Works part number ACC-308-BCG) is finished in black nitride and engineered for multi-caliber use across the AR-10 platform. It runs in .308 Winchester, 6.5 Creedmoor, 6mm Creedmoor, and any other cartridge sharing that same case head diameter, which makes it a practical choice for builders who swap barrels between calibers rather than committing to a single-caliber BCG. A smaller-diameter firing pin and firing pin hole help the carrier handle the higher pressures some of these cartridges generate, adding a margin of durability that generic BCGs do not always account for.
