"I bought this to mount on an Anderson Manufacturing lower, the fit and finish is excellent, and it cycles beautifully. YHM has always maintained a great reputation, and after buying this upper, I now know why! You won't be disappointed!"

"I bought this upper to mate to a CMMG lower. Put it all together and went to range. Dead on out of box at 30 yards and just had to do a minor adjustment at 100 with the rear sight. Right out of the box. I'm very happy with this upper. Well worth the money!!"

"Holy tack driver Batman! Dead on out of the box. Great mill work. Great setup for the money. Sure you can buy more expensive uppers, but why. Unless you use this extensively you don't need anything else. Did the break in with 55gr and was getting two inch groups at 50 yards(more me than the rifle, maybe). After 60 rounds for break in I switched ammo. Ran 30 rounds of 62gr and was getting one inch groups. As the forums will tell you 55gr is about the lowest you should go with 1 in 7. If I can remember I will post again when I get optics and push out to 100 and 200 yards."

"As soon as I saw this upper I knew I had to have it. I didn't want some generic looking AR that everyone else has. Put it on a Spikes Tactical lower. Fits great, looks awesome. It's nice because I have long arms so it shoulders nice, and I can put my hand anywhere down the forend. Already put a couple thousand rounds through it... shoots perfect right out the box. If you're looking to buy this upper you already know YHM makes great stuff and you're not looking for some cheap Mil-Spec upper. Great buy"
