These Centurion Arms Bolt Carrier Groups have been out for about a month, but now that they are making it to all Centurion Arms Stocking Dealers, it's worth taking a look at. Like all of Centurion Arms products, I expect nothing but high quality performance and specs from these Bolt Carrier Groups. Carpenter 158 is used for the Bolts, and they've been MPI and shot peened. The Carriers are also laser engraved with C4. Checkout our friends at Centurion Arms for more information.
