Wilson Combat TRBCANB308 Bolt Carrier Assembly .308 DPMS Steel

The Wilson Combat TRBCANB308 Bolt Carrier Assembly delivers enhanced reliability and extended service life for .308 Winchester AR-platform rifles. This precision-machined bolt carrier group features a nickel boron coating that reduces friction and simplifies maintenance while maintaining DPMS compatibility across multiple rifle platforms.

What Makes This Different

The nickel boron coating sets this bolt carrier assembly apart from standard phosphate-finished units. This advanced surface treatment provides superior corrosion resistance and self-lubricating properties that reduce bolt extension force by up to 85%. The coating penetrates the steel substrate rather than simply layering on top, creating a permanent bond that won't chip or flake under heavy use.

Key Features

• Nickel boron coating reduces friction and eliminates need for frequent lubrication
• Precision-machined from high-grade steel for dimensional accuracy
• DPMS-compatible design fits most .308 AR-pattern rifles
• Enhanced bolt extension with improved gas seal efficiency
• Staked gas key secured with grade 8 fasteners
• Magnetic particle inspected bolt for crack detection
• Shot-peened bolt for stress relief and fatigue resistance

This bolt carrier assembly maintains consistent cycling across various ammunition weights and powder charges. The nickel boron surface allows the bolt to run cleaner with minimal fouling buildup, extending time between detailed cleanings. Competition shooters benefit from the consistent lock-up and extraction, while tactical users appreciate the enhanced reliability in adverse conditions including sand, mud, and extreme temperatures.
