AR-10 .308 Bolt Carrier Group - Black Nitride

This AR-10 .308 bolt carrier group is designed to deliver consistent performance, durability, and reliability in large-frame AR platforms. Featuring a black nitride finish on both the bolt and carrier, this BCG provides enhanced corrosion resistance, reduced friction, and easier cleaning compared to traditional phosphate finishes.

Manufactured from 8620 steel, the bolt and carrier assembly are built to handle the increased pressures and recoil associated with .308 AR-10 rifles. The gas key is properly staked to maintain secure gas flow and dependable cycling under hard use. Each component is precision-machined and assembled to ensure smooth operation and long service life.

This bolt carrier group comes fully assembled and drop-in ready, making it an ideal choice for new builds, replacements, or upgrades. It includes the bolt, carrier, firing pin, firing pin retaining pin, cam pin, and gas key — everything needed for quick installation with no additional assembly required.

Compatible with AR-10 and similar large-frame platforms, this BCG is a dependable foundation for precision builds, duty rifles, and custom AR-10 projects alike.
