This is a great upper for the price. PSA doesn't skimp on the product quality. The upper came in protective packaging as well. Very clean, and more importantly, very accurate.
Finished project. PSA 18" upper, aero lower I had lying around with PSA lower parts kit.

Quality upper, I bought to interchange with the upper of the PSA 16" M4 5.56 NATO 1/7 Nitride MOE EPT Freedom Rifle With Rear MBUS ... for better long range coyote hunting & added a cawvalley compensator. For the price and quality you will not find one better.

Amazing quality, beautiful finish and pretty lightweight!
I love the way it feels, it is flawless, the finish is beautiful and I could compare it to a few hight/mid range uppers. I love the versatility of a 223 Wylde upper and the performance. I haven’t shot this upper yet, but the PSA name holds a lot of trust and value. Go head and pick up one or two of these, you won’t regret it!

Nice upper
If you want a little extra accuracy and speed this is a great upper, it is a tad heavy compared to some others but this helps with control and durability, unless you want to a carbon fiber barrel or guard to cut weight without losing durability, it's going to be all but perfect.

Excellent qualty, excellent fit, super accurate. Nice!
Almost 300 rounds since new and not a single failure. Wow! After hearing online how the occasional person has problems with uppers at this pricepoint, I am blown away! The only thing was to re-tighten the handgaurd

Met all my expectations
Shooting around 1 to 1.5 MOA at 100 depending on ammo and my old eyes. Any inaccuracy is due to the shooter not the assembly. I've feed around 300 rounds through so far without a single malfunction. Had never used M-LOK before but I've become a fan.
