Price point and the quality keeps me buying their barrels!
US7.5" Blackout will perform
Bought this barrel for ballistic testing for comparison to 8", 8.5", 9", and 10.5" that I have. While velocity is down slightly, accuracy was not. I would deer hunt with this length out to about 100 yards with no problem.
