Great upper for Plinking, Target, or hunting. May 10, 2017
Reviewer: david wong from garden grove , CA United States  
bought this about a year ago and has put about 500 rounds through it and it works very well.  at 50 yards I'm hitting groups .5 inch big drilling my rounds through the hole time after time.  this upper i set up as a plinker and my Semi Auto hunting rifle and i have already harvested a couple of deer with it.  only thing i have to say is the hand guard is a little big but can change it easily.  over all great upper and will look into buying another upper either another 300 black out or a 5.56 upper.

Worth the wait. July 9, 2016
Reviewer: Paul Heglund from Middlesex, NC United States  
It took 13 weeks but It came. It was worth the wait. I ordered a 300 blackout 16in FGS upper with 12 inch FGS free float Hand guard and 11 slot FGS rail. Finnish and fit to my AllStar Tactical lower are excellent, Tested 3 types of ammo thru it with no problems what so ever. All were supersonic. Precision one's 150gr Ballistic tip, Defender Ammunition's 150gr Sierra HPBT and Remington UMC 120gr OTM. Fired a total of 50 rounds, no FTF-eject or fire and that's with a 3 lb JP interprise trigger. Accuracy was best with the UMC putting in a 1inch group due to a dbl tap with 3 out of 4 rounds cutting just over a 1/4 inch. All groups fired at 75 yards from a bench. The other 2 were both 1 1/2 inch. I read complaints that some folks where getting their uppers with loose hand guard screws, miss-aligned gas blocks and shot out barrels. Not in this upper. Everything was solid on arrival and inspection straight out of the box.

Worth the Wait! June 26, 2016
Reviewer: Jerad Rardin from Columbus, GA United States  
It will take a while to get your upper! Mine took well over the the 8 week schedule. I have a feeling this is related to the demand for a well priced decent upper. That said, this upper is worth the wait. It is an incredible piece for such a low price!  You could pay more, but why?
