Eye-Catching Nickel Boron BCG For AR-10 Builds

The Aero Precision .308/7.62 Nickel Boron Bolt Carrier Group is an eye-catching addition to AR-10 builds that feature precise dimensions and superior coating ensuring the highest quality and correct component interface on .308 platforms.

It is the ideal upgrade from a Standard BCG to improve the looks as well as the overall performance and reliability on big-bore AR-10 platforms.

 

Durable MPI-Tested Steel Construction

The Aero Precision .308/7.62 Bolt Carrier Group is constructed from a combination of 8620 Tool Steel (Carrier) and case-hardened 9310 Steel (Bolt) for extreme durability.  It is then coated with high-quality Nickel Boron (NiB) which is much easier to clean than black nitride coatings as well as increases the overall lubricity of .308 builds.

The BCG is Magnetic Particle Inspected (MPI) to ensure there are no hidden cracks or stress points and all bolt components are shot-peened to reduce friction during use and ensure long-lasting reliable performance. Also check out the Aero Precision .308/7.62 Black Nitride Bolt Carrier Group for more options.
