"Fits both of my lowers (different manufacturers) and looks awesome. Hanging a few accessories off it, range time this week, can't wait to shoot it. Basically a Bushmaster upper at a better price. Quality is apparent."

"Over 500 rounds with various ammo and no issues. Accuracy is outstanding for a 16\" barrel. The guns shoots much better than I do. Fit and finish is perfect all over this upper (with one tiny little flaw in the flash suppressor).I've got a few more lowers to build up and my next upper will be a Windham."

"I purchased this upper and am very please with my choice. I bought a Spikes Tactical stripped Lower and after completing the lower assembly I put this awesome upper on it. It was a perfect fit! I Mounted a x4 scope on it and sighted it in at 100 yards. I can get 20 rounds in a 2 inch spread. The gun is very accurate and looks great. I'm very happy with this upper!!!"
