Availability: In Stock
The Wilson Combat Steel Nickel Boron Bolt Carrier Assembly for .308 DPMS AR platforms is built for shooters who demand reliability in .308 Winchester and related cartridges. This carrier is precision machined from aerospace-grade 9310 tool steel and finished with a polished nickel boron coating—the same components Wilson Combat uses in their factory-built rifles. If you're running a .308 AR, 6.5 Creedmoor, .243, .260, or other .308-based caliber and want a bolt carrier that handles high-pressure rounds without compromise, this is the real deal.
The heart of this assembly is durability under stress. The hardened 8620 carrier pairs with a machined S7 extractor rated for the sustained pressure of hot .308 loads. The gas key is properly staked—a critical detail that prevents a catastrophic failure when it matters most. That nickel boron finish isn't just aesthetic; it sheds carbon buildup and resists corrosion, making cleaning faster and keeping your rifle running longer between services.
Wilson Combat's reputation in precision rifle building comes from attention to details like this. They don't cut corners on internal components, and neither should you if your rifle is your tool. Whether you're running a match-grade build, a hunting rig, or a duty carbine, this bolt carrier assembly brings the same engineering standards to the parts that most shooters never see but absolutely feel.

Yes, this bolt carrier is made for DPMS AR .308 platforms and is the same component used in Wilson Combat's factory-built rifles.
The polished nickel boron finish reduces carbon fouling buildup, making the carrier easier to clean, and provides corrosion protection—especially valuable if you're shooting in wet or harsh conditions.
A properly staked gas key prevents it from rotating or loosening under firing stress, which could degrade reliability or cause a failure. It's a detail that separates precision builds from rushed assembly.
