Description

The Ideal BCG Upgrade For .308/7.62 Platforms

The Aero Precision .308/7.62 Bolt Carrier Group is the ideal upgrade from a Standard BCG to improve the overall performance and reliability on big-bore AR-10 platforms. Aero Precision offers this BCG in a black nitride finish that reduces friction, minimizes the need for lubricants and cleaning, and provides excellent corrosion resistance for a lifetime of use.

The carrier is machined to fit AR .308 compatible style AR Uppers and Rifles, and its multi-caliber bolt is designed to function with .308, 7.62×51, .338 Federal, and other .308-based cartridges.

Durable MPI-Tested Steel Construction

For extreme durability, the Aero Precision .308/7.62 Bolt Carrier Group is constructed from 8620 Tool Steel (Carrier) and case-hardened 9310 Steel (Bolt). It is then Magnetic Particle Inspected (MPI) to ensure no hidden cracks or stress points. It also includes a laser engraved ‘A’ logo for an additional Aero Precision classic look.

All bolt components are shot-peened and black nitride-coated to reduce friction during use and ensure long-lasting, reliable performance. Also, check out the Aero Precision .308/7.62 Nickel Boron Bolt Carrier Group for more options.
