Great components, great guy! I have 2 grendels and 1 5.56 all uppers from Grendel Hunter. I am extremely impressed with the quality of the products and the level of service provided! The turnaround time is superior to anyone else! The attention to detail is superior to anyone else! The accuracy if the 3 uppers I have is under 1/2 MOA at 100 yards! All chambers are on the snug side of tolerance. I suspect that lends to the accuracy I’m getting. I’m so pleased with the performance, I’m in the process of ordering another 5.56!

I don’t know that I can rate the rifle upper but I do love your website and being able to build my own rifle feature.
