I make Grendel Uppers I use myself. I only use quality American Made parts and the best most accurate barrels. I also supply the necessary parts to make the gun function properly. Assembled it to spec, the barrel nut is tightened and loosened 3 times before final tightening at 55 PSI. All parts are aligned and leveled and all screw are loctited and torqued. I have done a lot of experimentation with Grendel and I find the combo of a mid length gas system with a heavy buffer to be the most reliable so I include a buffer with the sale.
You will find cheaper Grendel Upper but you won't find a better one.
