Ballistic Advantage 5.45x39 barrel 16” 4150 chrome moly vanadium, mid length gas, m4 feed ramps, BAs proprietary chrome lining, I can’t remember what they called it. Troy rail, griffin armament comp. I built this back when 5.45x39 was ~13 cents a round and intended to train with it, but joined military and left in storage for over 10 years. BA stopped making these barrels a long time ago, they’re all dried up. Have guaranteed less than 500 rounds through it. It ran flawless with pmags with front follower tab cut off. Come check out the rifling, sorry I could not get a good picture of it.
