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.
Do I have to purchase the front and rear pins that hold the upper and lower together? Or are the pins included with either the upper or lower assembly?
Moe3rd on Oct 8, 2018
BEST ANSWER: The pins come with a complete lower assembly. The upper does not come with pins. If you are building your own lower, the lower build kits come with pins. Good luck with your new rifle!
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
BEST ANSWER: Yes I believe it will. I did not use the blackhawk. AR15 mil spec parts are interchangable
I am planning to buy another
Hope this helps

How does 55 gr 223 or 5.56 perform in this 1/7 twist barrel?
A.J.208 on Oct 27, 2018
BEST ANSWER: I have not fired the rifle at a range. So, I can’t give a good answer.
Is the barrel rifling polygonal?
Mark S on Aug 27, 2018
Which or any recommendations PSA complete lower that will match and fit with this upper please?
Gyogyo E on Aug 3, 2018
BEST ANSWER: This upper will drop onto pretty much any of PSA's (or really any Mil Spec) lowers and function fine. Pick the lower with the furniture you prefer and go with it.
Is this where I can ask a plethora of questions hoping others will help educate me to information that if I applied a smidgeon of effort in research and reading to educate myself I would become aware of the answer? (This applies to all products at PSA)

Smooth shooter
I really like this upper. I set it up with a 3x9x44 optic. The rifle length gas system is so soft and has been 100% reliable with less than average quality ammo. Only issue i had was that the screws on hand guard were loose. I tightened them down and they have held up perfect.

Great for the price.
Fit was good and it shoots relatively well for an AR. I'm not getting 1 MOA out of it, but I didnt expect to at this price point and an AR.

Great upper for the price
I bought this upper and put it on my S&W sport lower. Fit nice and shoots good. It seems to like brass casings better than the steel. Seems to have trouble picking up the next round with steel casings. Would buy again in the future.

I have submitted a photo of what this upper is capable of. It’s on palmetto state armories Facebook page. I couldn’t be more pleased and my friends more jealous.
