Kevin S's Review of Aero Precision AR-15 6mm ARC, 6.5 Grendel Bolt Carrier Group (BCG)

I bought this to upgrade a milspec Bear Creek Arsenal upper chambered in 6.5 Grendel. To my surprise the bolt would not close a GO Gauge as the headspace was too short. I returned it and used the original one the upper came with.
