- Great fit and finish! Review by Mandy
Quality Price Value
So bought this upper for my noveski lower pistol I built and was extremely satisfied with fit and finish, they came together perfectly with zero play and especially because the lower is black and I bought the upper in fde it still looks like it was meant for each other.
Now for the important part, range time! Did a quick clean before taking it out. It was dirty, I do believe they test fire before sending out which I appreciate! I have 300 rds that went down range with this gun. At first I was zeroing so would send 3 rounds down, open her up then clean it with a few patches then repeat. Did this till I was zeroed at 25 yards. The only issue I had at first was the bolt would not lock back. Probably after the 12th round it started to lock back, but that was probably because it was a new buffer and spring designed for 5.56 and the 300 blackout doesn't have as much pressure.
But after 4 sets of 3 rounds it was locking back.
After sighted in I ran 30 rds bump fired without a hiccup.
Then took it to 50 yards. This is where I was most impressed, I was sending rounds down with flip up iron sights staying in a 2-2.5" group, was very accurate for a 10.5" barrel and shot extremely well and not one ftf out of 300 rds with 125 grain defensive rds and 124 grain fmj.
So I am extremely satisfied with my upper and do recommend it, and the fde matched dead on with my fde magpul grip, magazines, and thordson cheek rest. (Posted on 5/28/2016)
