Wilson Combat engineered this bolt carrier assembly to deliver reliable performance across demanding conditions. The component features a polished nickel boron coating and is precision machined from aerospace-grade 9310 tool steel, delivering exceptional toughness. The hardened steel 8620 carrier incorporates forward assist cuts for enhanced reliability, while the gas key is properly staked to prevent failure when it matters most.
This assembly drops into any quality 5.56 case head based AR rifle, including those chambered in .223/5.56 NATO, .300 Blackout, .204 Ruger, 300 HAM’R, or 7.62X40 WT. The polished nickel boron coating simplifies cleaning and resists corrosion. Both the ejector and extractor are machined components. The same bolt carrier assembly is used in Wilson Combat’s fully-built rifles, delivering the unbeatable performance and durability that demanding shooters require.
