Brownells M16 Bolt Carrier Group 5.56x45mm/.300 AAC Blackout/.223 Remington, Chrome

The Brownells M16 chrome 5.56x45mm complete bolt carrier group is a meticulously crafted component that pays homage to the classic design of the earliest AR-15 and M16 rifles. This bolt carrier group is a perfect blend of vintage aesthetics and modern engineering, making it an ideal choice for enthusiasts and collectors aiming to recreate the iconic look and feel of retro firearms. At the heart of this assembly is a bolt machined from high-quality 9310 steel, renowned for its strength and durability. Each bolt undergoes rigorous magnetic particle inspection to ensure it meets the highest standards of reliability and performance. The bolt, along with the carrier, is finished with a matte silver chrome coating, providing not only a striking appearance but also enhanced corrosion resistance. The carrier itself is constructed from 8620 hardened steel, ensuring robust performance under various conditions. This durable chrome application extends to the extractor, gas key and cam pin, ensuring that all moving parts are protected against wear and corrosion, thereby enhancing the longevity of the component. Designed for versatility, the Brownells M16 chrome 5.56x45mmx45mm complete bolt carrier group is compatible with rifles chambered in 5.56x45mmx45mm, .300 AAC Blackout or .223 Remington. This makes it a versatile choice for a wide range of builds, whether you're aiming for a retro aesthetic or simply seeking a reliable upgrade. For those looking to replicate specific historical models, this bolt carrier group is available in two configurations - with or without forward assist serrations. The model without serrations mirrors the original BCG found on early AR-15s, such as the Air Force 601, while the serrated version reflects the design used in early XM16E1 models from the mid-1960s. Each Brownells M16 chrome 5.56x45mmx45mm complete bolt carrier group includes a bolt, bolt carrier, gas key, firing pin, cam pin and a firing pin retaining pin, providing everything you need for a complete and authentic build.
