I was nervous purchasing this at first because of the price being so cheap. But after reading the reviews i decided to get it and I'm glad i did. It went together perfect and have already put over 1000 rounds through it with not a single malfunction. And the rounds i shoot are not the best. This was my first experience dealing with and i am more than impressed. I have found my one stop shop for all of my carbine needs.

Looks great.


If there's a blemish on it I can't find it. Will definitely order again.

Excellent value


If you are in search of a quality upper receiver for your first or next AR build then look no further. Given the price you'd be expecting to see all types of corners cut but that is NOT the case here. Excellent service and excellent part.

great price


If you must have T marks then you'll need to pay more. If you can count to ten without help then this is all the upper you need. As well made and finished as more expensive uppers, just no T marks.

Great upper


Is up to spec, no blems. Very well made, all dimensions are accurate, M4 feedramps are well cut. As well made as a Spikes (Aero). Will definitely buy again.

Nice upper, but a tad loose on my Andrrson lower.


It fits a little loose on my Anderson Lower, but for the price it isnt worth docking a star... By a little, I mean in the realm of 0.5mm of slack. The carrier group and barrel ought to tighten everything up nicely. Definitely worth it, and I highly recommend buying through Primary.

Great product, price, and fast shipping!


Item arrived very quickly and functions perfectly! Best price I found online!

Great product

Great quality


It's a cerro forge "keyhole" always great quality.

Good Upper


It's a good upper, the one i recieved didn't have any blemishes on it. Fit lower well. Will defiantly get more for future builds
