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.


With multiple 5-Star online reviews at the time of writing, this Aero Precision 7.62/.308 Bolt Carrier Group is a popular choice for the AR10 platform. Plus, the satisfaction guarantee means that if you're unhappy for any reason, you can return it to us within 30 days for a full refund.

Arrived as described

Aero precision has met and surpassed my expectations time and time again. Definitely glad I went with their .308 BCG. Arrived quickly from AR15 Discounts and at a great price.

Excellent BCG

My example of Aero Precision’s nitride .308 BCG was excellent. It didn’t have a sticky bolt like I have read and paired with the upper and lower set from Aero Precision it is flawless.
