Engineered for precision and durability, this .308 Winchester DPMS-compatible AR bolt carrier group is a premium choice for custom rifle builds. Manufactured in the USA by a Mil-Spec contractor exclusively for Wilson Combat, each complete assembly is finished in corrosion-resistant Nickel Boron (NB) for smooth operation and enhanced wear resistance. The bolt is CNC-machined from Carpenter 158 steel and features an S7 tool steel extractor along with a hardened ejector for reliable cycling under demanding conditions. The carrier, made from 8620 hardened steel, is designed without forward assist cuts, ensuring clean, consistent movement. A properly staked gas key adds to long-term reliability, making this bolt carrier group an ideal match for precision barrels and high-performance .308 AR platforms.
