The Aero Precision Pro Series 5.56 Bolt Carrier Group is a high quality AR-15 bolt carrier group made from machined steel. This bolt carrier group is the perfect compliment to our stripped upper receiver. For those who are building their own AR-15, this Aero Precision bolt carrier group delivers a high standard of performance. The Pro series BCG has all the same great features of Aero Precision’s classic BCG, but is optimized to provide longer service life.
Comes in Black Nitride.
