Fail Zero AR10 Bolt Carrier Group .308 Black DPMS

Fail Zero AR10 Bolt Carrier Group (.308 Winchester, DPMS Pattern)

This is a complete, factory-assembled bolt carrier group engineered for AR10 rifles chambered in .308 Winchester. It arrives ready to drop into any mil-spec AR10 upper receiver and requires no additional assembly or fitting.

Superior Surface Technology

All critical components—bolt, extractor, cam pin, carrier key, and firing pin—are treated with Fail Zero's proprietary EXO Nickel Boron coating. This advanced surface treatment delivers:

• Permanent dry lubricity without requiring oil or grease
• Extreme durability that resists wear under sustained use
• Superior corrosion resistance for reliable performance in harsh environments
• Reduced friction that improves overall rifle reliability and cycling

Design and Finish

The carrier features a black topcoat exterior for non-reflective, tactical appearance. The coating is engineered to wear naturally at contact points—ramps, rails, and carrier ends—gradually exposing the bright Nickel Boron finish beneath. Non-wear areas, including the dust cover, retain the black finish. This natural wear pattern is normal and does not affect performance or warranty coverage.

• Bolt (.308 compatible)
• Bolt carrier
• Extractor

This is a quality upgrade for shooters seeking improved reliability and reduced maintenance in their AR10 platform rifle.
