Wilson Combat AR-15 Bolt Carrier Assembly 5.56 NATO

Wilson Combat AR-15 Bolt Carrier Assembly

The Wilson Combat bolt carrier assembly represents the kind of precision engineering that separates quality components from the merely adequate. Built to the same standards as Wilson Combat's factory rifles, this carrier delivers the reliability you need when it matters most.

Construction & Materials

Aerospace-Grade Steel: The bolt itself is precision-machined from aerospace-grade 9310 tool steel, a material chosen for its exceptional toughness and resistance to wear. The carrier is hardened 8620 steel, providing the durability required for thousands of rounds downrange.

Black Nitride Finish: The black nitride coating protects against corrosion while maintaining a professional appearance. This finish is harder than standard parkerizing and resists wear from repeated cycling.

Reliability Features

• Properly staked gas key — Won't loosen or fail under sustained fire
• Forward assist cuts — Engineered into the carrier for added reliability
• Precision-machined ejector and extractor — Ensures consistent case removal and feeding
• Drop-in compatibility — Works with any quality 5.56 case head AR-15 platform, including .223 Remington, .300 Blackout, .204 Ruger, .300 HAM'R, and 7.62x40 Wilson Tactical

The Wilson Combat Difference

This is the same bolt carrier assembly used in Wilson Combat's fully-built rifles. It's built for shooters who understand that reliability isn't negotiable—whether you're at the range, in competition, or depending on your rifle when it counts.
