How does AA mark their barrels?
Yesterday, I came acrossed an AA upper(stamped Alex-A) with a 19.5 heavy barrel attatched. The only marking I saw on the barrel was "6.5 Grendel". Was this one of their earlier barrels? The barrel threading seened strange, looked like 3/4- 16 but I didn't have my glasses. Just curious
