Details:

Since a bolt carrier group (BCG) is critical for the overall performance of an AR rifle, you should always choose a brand with a reputation for excellence, such as CMC Trigger.

The CMC Trigger Enhanced Suppressor Optimized .308 Bolt Carrier Group is designed to chamber and fire rounds with the utmost precision and uncompromising reliability. You can count on CMC Trigger to machine each part to the most exact Mil-Spec tolerances. This .308 BCG is heat-treated and undergoes full HPT/MPI testing.

An impermeable coating of black nitride is applied to all of the parts. This type of coating is known for reducing friction, eliminating corrosion, and preventing wear. The black color of the coating is also great for those who are building a camouflage rifle; it is not as easily visible as chrome or nickel-plated carrier. Fewer contact points with the black nitride finish of the carrier create a naturally low-friction surface that repels fouling and corrosive elements.
