I purchased this barrel, a CMMG bolt, and a CMMG upper in the hopes of mating them to a dedicated PSA 9mm lower. This barrel works exceptionally well, is very accurate and has not had a single hiccup with a number of different FMJ projectiles, but when attempting to cycle JHPs the bolt/barrel fails miserably leading to a failure to feed every single time. So far I am pleased with it, but would be much happier if I could find a quality JHP it would cycle well.
This barrel is as advertised, fit and finish were above my expectations, fits mil spec upper with no problems. Fast turn around on delivery. Would recommend this barrel to others for their SBR.
The barrel came in a plastic tube and was wrapped as well. Fit and finish met expectations. The muzzle threads were perfect and it fit my upper without difficulty. Haven't shot it yet, but expectations are high.
