"Dam this upper is hot! Great addition to my m4! Great deal! Better than buying a full gun just snap and go! Old farts at the range say \"dam is that a .50, loud enough to be!\" Great upper.Wish the 20\" barrel came with the a sight rail in front as well like its little brother, and one more mag!Joshua"

"A great price on a great upper. I hopefully it comes back in stock.It shoots great 1.5\" groups at 150yds with Hornady rounds. Just wish ammo was more plentiful and cheaper."

"I got this upper after seeing various YouTube videos about it, and 1 hunting show, showing them using the .450 Bushmaster on hogs. I took it to the range the other day, to zero it, as well as see for my own eyes how accurate it is... All I can say is WOW!!! I have used a variety of big bored rifles, and to date, I have NEVER seen one as accurate as this!!! At 100 yards, I was able to group 6 shots in 7/8 inch!!! I can't wait to try it on these SW Oklahoma hogs!!!"

"This is probably the best investment I have made to date for an AR platform. Shooting the Hornady 250 grain FTX, this upper produces sub-MOA at 100 yards!!! First time I have EVER seen a big-bore rifle shoot that accurately. So far, I have used it to kill a whitetail doe at 92 yards, and my wife used it on a 175 lbs. hog at 30 yards. Both went down instantly. I do recommend that you get a heavy buffer spring for this, not so much for the recoil, which in my opinion is comparable to a 20 gauge shotgun, but to allow for faster follow-up shots."
