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.
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: This is a complete upper assembly. No additional parts required.

Good quality Good value
This is my first AR15 build. I think this is a great upper for the price, haven't had any issues with it so far. I would recommend this product.

Very happy
This is my favorite rifle by far. Accurate and stable follow up shots that cut holes.

The biggest reason I gave it 5 stars is 6 wasn’t an option. You don’t expect this kind of quality for the price asked. Very happy with it.
Just received my upper today, the fit and finish on this piece is outstanding. Well balanced lightweight, after handling my piston upper it was a pleasant surprise. I wanted at least one upper you didn’t mind carrying and this one is it. The nickel boron bolt group is highly polished, should be a breeze to keep clean. Can’t wait to get out on the range with it.

Great upper
Bought this a few weeks ago and I love it. Very accurate and built very well. It was my first psa upper but won't be my last.

Excellent hunting upper
Quite pleased with this upper.
Out of the box mounted Vortex 4-12 and headed to the range.
Fired 2 mags (30) of 556 fmj to function check. 2 FTF in the first 10 rounds attributed that to being new as all malfs went away after applying a quick shot of CLP to the bolt.
Switched over to some hunting loads to see what the barrel liked best. (Fusion MSRs 55 and 64gr Gold Dots Hornady SPs).
All functioned flawlessly and were sub MOA @ 100 yards. Best grouping ammo was the 64gr Gold Dots. 5 shots avg @ .48". I could've tightened that up had I remembered my rests.
Highly pleased with this setup. Can't wait to get it bloody on yotes this fall and hopefully deer in a year or two if the PGC ever allows it.

Very nice
I have to say I'm impressed. Just received this yesterday withdrew 3 day shipping. The 18" as barrel looks so nice with the M-lok upper and man is that forearm light! This upper actually feels about the same weight if not just a bit lighter than by A2 front post flattop 16" upper. Points great. Haven't had a chance to complete barre break in yet so I will update review when I've had a chance to shoot it. Only dislike is the black A2 birdcage flash hider but that's easily enough changed in time. Looking for a light weight 18" upper? I recommend this one!

Looks good in theory..
This is my 4th completed upper that I have purchased from PSA. The first three have been great and i love them I expected the same quality out if this upper. Had all the right specs that i was looking for and when i saw the price it was an immediate buy. When i got it in the mail i was immediately disappointed. The quality of the upper receiver looked and felt cheap. There was practically zero finish on the inside of the upper. You could see tool marks on the receiver the rail and the flash hider. The bolt feels like its worth maybe 20 bucks. I figured okay its ugly but its gonna shoot fine. I took it out to the range and had consistent failures. Failure to feed almost 100 times the first trip out. When it did feed it wouldn't eject so i ended up with a spent round in the barrel and a live round right behind it. Complete disappointment from this thing.
