Awesome Upper for the money!
Got this upper recently and absolutely love it. Didn't have any issue what so ever when I took it to the range. It ran 90 rounds of 55gr. xm193 ball just like a charm. Fit and finish is perfect, and it came right in time. Thank you PSA for making such an awesome upper!

PSA comes through again
Put together my first AR on a shoestring, using a PSA rifle kit and a locally sourced stripped lower. Went together quick and easy, and worked flawlessly from the first trigger pull. Decided I wanted to upgrade, and chose this upper, and I couldn't be happier. Fit and finish is excellent, balance is very good, and like my first rifle, this thing just works. The main reason for upgrading was accuracy, and this didn't disappoint, with the right ammo, I consistently get sub-MOA 5 shot groups, and that's factory ammo, I haven't started load work up yet.

Almost forgot, the most frequent complaint I see about PSA is slow shipping, I've had around half a dozen transactions with them in the last year, every order has arrived in less than a week, and I'm on the opposite side of the country, AND in the boondocks! Will definitely continue to do business with them.

Great value for the price
Put this upper on a spikes lower, purchased a PSA bolt and BCM gun fighter charge handle. Changed out the flash hider for a JP brake and went to the range. Dailed the gun in from a rest at 50 yards with a 55 gr factory load. After the 1st 20 rounds i cleaned the barrel and wow, the groups really tightened up. 100 yard shots were .5 moa with off the shelf Independence AR-556. Cant wait to try some of my 55 gr. hand loads.

Perfect!!!
Received this upper, intact and packaged well !! Once assembled, I took it to a range for a "live fire & function" test. No optics yet... but it functioned, and cycled 5 different brands of 5.56 ---- even some steel cased ammo. NO issues at all.

Good upper
The upper is very accurate. I used an Aero precision lower for this build and the fit was perfect. No wobble.
Very accurate and shoots well. I used a Aero precision lower in this build and the fit was perfect.

Very nice, love it!
My father purchased this one and it is very clean and accurate. The handguards are surprisingly nice at this price point. Needless to say, I own one now also.

Awsome deal!
While researching a build I came across this upper. It was all that I was loking for except for that it wasn't mp or hp inspected. For the price I thought that I would take a chance and I am glad I did. I waited to write this review untill I took it to the range and shoot it a bit. I had concerns about dwell time on the 18" barrel with a rifle length gas system. After putting 250 or so rounds down range I have to say that I am very pleased. No short strokes ejection pattern was perfect. I do have to say that my concerns with the possible dwell time issues swayed me to install a Sharps Rifle Company BCG and a Tubbs flat wire buffer spring to try to avoid any problems right off the bat. That being said I had zero malfunctions. I would recommend this upper to anyone that wants a quality accurate upper for a fantastic price. Time will tell the true story I will try to update this review if something "goes south".
