Classic Retro Chrome M16 Bolt Carrier Groups match the finish of the bolt found on the earliest AR-15 & M16 rifles.
The Brownells M16 Chrome 5.56 Complete Bolt Carrier Group included a bolt machined from 9310 steel, which is magnetic particle inspected & finished with a matte silver chrome finish. The carrier is fabricated from 8620 hardened steel and also receives the same, durable chrome application. In addition to the bolt and carrier, the extractor, gas key and cam pin also are chromed to ensure all moving parts are corrosion resistant. The Brownells M16 5.56 Chrome Complete Bolt Carrier Group is designed to work easily and reliably in any AR-15 or M16 rifle chambered in 5.56x45mm, 300 AAC Blackout or .223 Remington.
The perfect complement to a retro build, these BCGs are available without forward assist serrations. The model without serrations is similar to the original BCG found on early AR-15s, such as the Air Force 601.
The Brownells M16 Chrome 5.56 Complete Bolt Carrier Group comes with a bolt, bolt carrier, gas key, firing pin, cam pin and a firing pin retaining pin.
