Wilson Combat AR-10 Bolt Carrier Assembly .308 Win

Wilson Combat AR-10 Bolt Carrier Assembly for .308 Winchester

This is a purpose-built bolt carrier assembly designed for serious shooters who demand reliability in their .308 Winchester AR-platform rifles. Wilson Combat has engineered this component to the same exacting standards found in their factory-built rifles.

Construction & Materials

Aerospace-Grade Steel: The bolt carrier is precision-machined from aerospace-grade 9310 tool steel, a material selected for its exceptional toughness and durability under the demanding pressures of .308 Winchester and related calibers.

Nickel Boron Coating: A polished nickel boron finish provides superior corrosion protection and makes field cleaning significantly easier. This coating resists fouling and maintains its appearance through extended use.

Critical Components: The assembly includes a hardened S7 tool steel extractor and precision-machined ejector, both engineered to reliably handle the pressures of hot .308-based loads.

Reliability Features

• Properly staked gas key ensures the critical seal won't fail during operation
• DPMS-compatible design fits standard AR-10 platforms
• Smooth carrier design without forward assist cuts for maximum reliability
• Weight: 18.6 oz.

Versatility

While designed for .308 Winchester, this assembly functions reliably across the entire family of .308-based cartridges, including .243 Winchester, 6.5 Creedmoor, .260 Remington, and .338 Winchester Magnum.

This is the same component Wilson Combat uses in their production rifles—proven performance you can trust.
