The bolt carrier group is the heart of the AR-15’s direct impingement operating system. It contains the bolt, bolt carrier, firing pin, cam pin, and firing pin retaining pin — all the components that chamber, fire, extract, and eject each round. Anderson Manufacturing BCGs are machined to mil-spec dimensions, ensuring compatibility with standard AR-15 and AR-10 upper receivers and barrels from any manufacturer. Bolts are produced from Carpenter 158 steel and magnetic particle inspected (MPI) before assembly to detect surface and subsurface defects. Carriers are machined from 8620 steel and heat treated to mil-spec hardness. Finish options across the Anderson lineup include phosphate for standard mil-spec corrosion resistance, nickel boron for improved lubricity and easier cleaning, and nitride for a harder, more corrosion-resistant surface. A full-auto profile carrier is standard across the Anderson BCG lineup and is compatible with all semi-automatic AR-15 lower receivers. For builders assembling an AR-15 from components or for owners replacing a worn BCG, an Anderson Manufacturing BCG machined to mil-spec tolerances cycles predictably across standard carbine, mid-length, and rifle-length gas systems when paired with the correct caliber barrel.

Frequently Asked Questions
Is this BCG compatible with standard AR-15 uppers?
No. The Anderson .308 BCG is designed for AR-10 and DPMS-pattern .308 upper receivers. It uses a larger bolt head and carrier than AR-15 BCGs and is not interchangeable with standard AR-15 components.
What finish does the .308 BCG use?
This BCG uses a nitride finish, which provides excellent corrosion resistance and a harder surface than standard phosphate. Nitride-finished BCGs also run well with reduced lubrication compared to phosphate alternatives.
What calibers does this .308 BCG support?
This BCG is designed for .308 Winchester and 7.62×51 NATO. Confirm your barrel’s chamber specification and receiver pattern before ordering to ensure a proper fit.
