When it’s time to upgrade your AR-10 or build yourself a new precision platform, the Aero Precision .308 / 7.62 Bolt Carrier Group is a stellar choice. It matches other top-of-the-line .308 BCGs feature for feature and and is built to last. Aero Precision is a well-known company with a solid reputation for quality.


The Aero Precision .308 / 7.62 Bolt Carrier is compatible with most AR10 and AR .308 systems. The carrier is CNC machined from case-hardened 8620-steel and has a Black Nitride finish. The bolt body is made of case-hardened 9310-steel, the gas key is made of 4130-steel, and both feature a Black Nitride finish. The 4340-steel extractor is built tough with double springs and double O-rings. The firing pin is manufactured from 8740-steel and hard chromed for increased wear resistance. It has a full-auto profile with forward assist serrations, but simply installing this BCG will NOT convert your AR10 to a full-auto platform. This high-quality .308 / 6.5 Creedmoor / 6mm Creedmoor BCG weighs in at 18.24 ounces and is proudly made in the USA.
