Spikes 5.5 inch 9mm barrel in black nitride has been the right pick for a 9mm SBR. 1:10 twist stabilizes both 124 and 147gr loads. Chamber polish is good. Heats up fast as expected with a short barrel.
Spikes Tactical 5.5 inch 9mm barrel groups consistently at SBR distances. 1:10 twist stabilizes both 124 and 147gr loads. Black nitride is holding up to suppressed shooting heat. Chamber finish is smooth. Good barrel for a compact 9mm AR.
