Over the last year, I’ve ordered several items here and there, all have been as described, within specifications, and had the looks to go with it… This upper was meant to be part of a build for a “throw around” truck gun, and for the price point, I was willing to try it. I have already put several hundred rounds through it, with zero failures, zero….. it operates as smooth as any of my mid to upper tier weapons, which was extremely rare and mind blowing… with further testing, mounted in a bench vise, @100yds weapon was consistent with 1.25″ to 1.5″ groups, running 62gr match, and 2.5″ groups with basic PMC 55gr. Which surprised me…. furthermore, I was curious to see if accuracy would remotely maintain after some extreme heat, so upper was mounted on a Colt FA lower, and also ran flawlessly, with no adjustments necessary. After several harsh runs, barrel maintained accuracy!!! Extremely pleased with this upper! Thank y’all for providing a product that actually functions like it should, right out of the box!!!
