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.
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)
S T on Nov 14, 2018

No effort required.
Will this work with SKU: 7779347?
Derek W on Oct 28, 2018
BEST ANSWER: Yes, it will work with the upper that you have designated.
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 should be part of a complete lower. If you are buying everything separate ie stripped lower, then yes you will need to buy pins to complete the lower.
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: I don’t believe so.
How does 55 gr 223 or 5.56 perform in this 1/7 twist barrel?
A.J.208 on Oct 27, 2018
BEST ANSWER: It still stabalizes them pretty good. Been shooting 400 yds ar clays and it does just fine.
Who’s the barrel manufacturer of this uppers barrel?
JoshJ J on Oct 16, 2018
BEST ANSWER: Most likely PSA. Google search "PSA Our Story" and watch the video. PSA now makes most AR components.
Will this upper ship to my home in Texas? thank you in advance.
K. D. P on Oct 12, 2018

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.
I received this upper for Christmas. What a great surprise! I have a Ruger AR 556 chambered in .556. Fit great with no issues. Have not fired it yet. Will this upper cycle properly with my original Ruger AR 556 buffer and spring?
Abe Garcia A on Dec 26, 2018

Couldn't be happier
Very accurate barrel, one inch groups at 100 yrds with 55 gr. .223 factory rounds. Can probably squeeze a little more out of it with handloads, very pleased.........

Works for what I need it to
The upper is exactly what I needed when I bought it. It's sitting on an SCR lower and wearing a Vortex 6-18x scope, and I use it for predator hunting, mostly on things lie bobcats and coyotes. It works fantastically for that purpose. I was pleasantly surprised by the handguard, it being much lighter than I normally see from PSA.

Short stroking issues
Part looks great, does not function correctly. I have tried a couple different buffers, and the rifle seems to short stroke. I had to realign the gas block, but that still hasn't fixed the problem. Next step will be to cut off a few of the coils from the buffer spring. The ejection pattern of the shells looks good, just don't think the bolt is coming back far enough. Might also have to continue to break in the rifle. The bolt and rifle hve been cleaned after each outing.

Another great one!
Like all of my PSA goodies, this one rocks! Fit and finish are great. Anyone looking to buy this should take the plunge, I definitely recommend it. The only thing I did was switched the flash hider to a SS flavor. Thanks again Palmetto!

Very accurate and fits perfectly. I will add a lower picatinny rail, but I knew it did not come with that.

Love the ease of order, price, options, and fit/finish of guns. I'm not a gun aficionado by any means, but every piece I have ordered has been well made and accurate. Thanks PSA for good quality with the price!
