does this upper have everything you need to build it or will I need to but a parts kit?
Jonathan B on Apr 13, 2018
BEST ANSWER: Upper assembly is complete. All you need is a lower assembly to attach it to and a sighting system.
will this upper fire both .223 and 5.56 ammo?
jim k on May 3, 2018
BEST ANSWER: Yes. Fired about 100 rounds of federal xm193 through mine, and the other 200 or so rounds have been .223 Rem of different types. Both have worked well in this upper in my experience.
Is this classified as a pencil barrel?
Klowe on Sep 16, 2018
BEST ANSWER: No, the lightweight part is the lightweight handguard. Description even says "Barrel Profile: A2 Style" and .750 gas block.
Will this fit the psa ar15 complete blackhawk classic lower?
Lupe N on Aug 1, 2018

Hope this helps

Dollar for Dollar best Ar I have found.
I bought this upper with one of PSA’s MOE lowers and they fit together like a bank vault! The bolt action is smooth. I have a couple AR’s that I paid 5 times more for and so far the only thing I can say is that they have nicer rails (although I have no complaints about the PSA rail) and the PSA upper and Lower fit together tighter with absolutely zero play. I may have gotten lucky but that is my experience. I haven’t grouped the rifle yet to comment on accuracy but as far as reliability it has been flawless. I do have a buddy that has one with the keymod rail and he is getting sub moa with handloads.

Not as good as I expected
I received the upper quickly in a well packaged box. Very lightweight compared to others I have . I was concerned with heat with how close the barrel is to the hand guard, but after shooting 40 rounds it was fine.. now the problem is the hand guard coming loose after that same 40 rounds. I couldn’t figure out why the iron sights were not zeroing out. Then I saw the hand guard lose and twisted slightly. I reset it with blue loctite and will let it dry a few days and try again.. disappointing, glad I didn’t have to take it to combat. I can’t give accuracy information considering what happened.. quality control guys

So far, so good
I’ve had it to the range to sight in the scope. Just a cheap $100.00 scope but it shoots better than I do so I’m happy with it.

Great upper
Very pleased. Accurate and consistent, weight is light and everything worked great putting this on my Bushmaster lower.

It's been good
The barrel married up great to the PSA upper.
The groups are not as good as the photo you see on these review. Granted, we've only got 200 rounds through it so far.
I'm sure with cleaning up the barrel and smoothing out any chatter marks. I'll get it running better.
Overall, no complaints.

PSA .223 wylde upper
for the money, you can't beat it, accurate,solid and physically as good as any 5-600 upper...why pay more from a "name" brand, you're getting the same components, put together by experienced gunsmiths and you know the QC is top notch

Great Upper assembly
Fit and finish are great. I was looking for just a barrel for a build and ran across this. This entire assembly was almost the same cost as a barrel alone so I bought it instead. Really nice. Would buy again.
