A yes and no! - Ammo, Inc. StelTH .300 AAC Blackout 220 Grain Total Metal Jacket Brass Cased Centerfire Rifle Ammunition

I was able to get it to cycle. First try was 16" barrel ultra light piston gas system + BCG. It was a no cycle. In short eventually I dropped in shorter lighter AR-15 spring. Went adjustable gas block direct gas impingment. Standard BCG and Strike industries Optimus adjust buffer at super light. After tuning gas block it began to cycle fairly well. Also running banish .45 suppressor. Last time I fired I let out a quick group of 8 rounds and they cycled great. Not the best rounds in the world but a choice for target shooting and general sight in. Lowest price option I have seen on S.S. rounds. Lol my .308 uses lapua S.S. that is like $60.00 a box.
