Ballistic Advantage 5.45x39 barrel 9.5” 4150 chrome moly vanadium, carbine length gas, m4 feed ramps, BAs proprietary chrome lining, I can’t remember what they called it. Troy rail, Spikes tactical dynacomp. 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. Very few rounds through it, I would guess 200ish. It ran flawless with pmags with front follower tab cut off. Shoots massive fireballs. Come check out the rifling, sorry I could not get a good picture of it.
