Sounds nice! Mine is a M5E1 Craddock Percision 24" Bartlein barrel. It's a pig but worth the hump!I went with the M5E1. Ballistic Advantage barrels are quite heavy, so with that weight, the M5E1 is the best way to go. The barrel change I went with BSF carbon fiber that reduced the weight by three pounds total weight now is 11 pounds. This AR-10 is more accurate than I can be. I'm getting group sizes under a half inch or smaller. One six rounds group almost quarter inch. There is a lot of quality barrels on the market, it all depends on how much you are willing to spend.
