What is the correct buffer and spring for this upper assembly?
Ernie S on Apr 5, 2019
BEST ANSWER: Yes I am curious as well. Uses rifle length gas system so I'd assume rifle buffer would be ideal. However, this is basically a Mk12SPR upper, and I believe (Don't hold me to that..) they used both A2 stocks/buffers as well as CAR stocks/buffers, so will both work? Will one work better?
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
BEST ANSWER: Yes, I believe that most people here will do all the leg-work for you.
No effort required.
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: Upper assembly is complete. All you need is a lower assembly to attach it to and a sighting system.
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.
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 a free floating barrel?
don c on Feb 13, 2019
BEST ANSWER: Don, that is indeed a free floating barrel.
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 work with SKU:516446916
And what do I need to mount a grip on the front?
Tennessee B on Jan 25, 2019
BEST ANSWER: Yes this will work with that lower no problem. I added a foregrip but it is not needed. Depends your grip, how you shoot. foregrips are great for control, try a few and see which one works well with your grip. I love this upper its on my long range AR and is shooting 1" groups all day long.
Will this fit the psa ar15 complete blackhawk classic lower?
Lupe N on Aug 1, 2018
BEST ANSWER: Yes, this will fit. You might experiment with different weight buffers to get the exact performance you want, but the upper and lower fit is perfect

I'd this a fn made barrel?
Joey H on Oct 31, 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.
What's the accuracy on this barrel? What typical MOA will this shoot with 55 or 62 grain rounds?
DanDaMan on Apr 19, 2019
BEST ANSWER: With run of the mill 55-62gr fmj expect about 2 moa
Because that's about as good as those rounds will shoot through most anything.
With this upper I have shot 5 shot sub moa groups with Hornady 53gr superformance varmint.
The federal predator/varmint 50 gr hollowpoint also shoots sub moa.
Will this be shipped to california? I have fixed mag so i can use flash hider, but some sites dont care.
patrick t on Apr 6, 2019
BEST ANSWER: Yes. There's currently no restrictions for any AR parts to CA to include lower receivers. Lowers have to be shipped to a FFL while everything else goes straight to your home.
Will the Magpul Industries Sling Attachment, M-LOK, Quick Detach MAG606 fit the handguard?
JoeRoch on Jan 27, 2019
BEST ANSWER: Yes, it will fit because it is compatible with the M-Lok upper rail. I see no reason why it would not fit.
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
BEST ANSWER: I bet it did.
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.

K. D. P on Oct 12, 2018

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

Very accurate upper
Hits a dime at 100Yds as long as you are using 62 grain ammo. 55 grain is erratic, 62 to 70 grains fly best. Hornady Frontier 62 grain hollow point has the best MOA.

Very nice. Definitely worth the money!
Nice upper. I can’t give a really good review on it because I haven’t shot it much. But it does look good and functions just as it should. I will be buying more from PSA

Awesome upper for the money!
I’m super happy with this upper. I honestly didn’t expect much for the price but one trip to the range and I was pretty excited about it. After some load development, (it loves hornady 52 gr ELD’s sitting on 27 gr of varget) I’m blown away! Wasn’t expecting a sub moa rifle at this price point. Probably gonna have to get that .308 next!
52gr Hornady ELD and 27 grains of Varget seem to be pretty legit in my new upper 😁...

Very pleased now
I purchased this upper in August of 2018 and just recently got to try it out. Accuracy was amazing with 855 5.56 55 gr but would not cycle steel cased or federal 223 brass. I contacted PSA customer service and with no hassle at all sent a returne label to me. I got my upper back within two weeks and just tried it and flawless performance. I would recommend this upper if you are looking for that bit more of accuracy. I am very happy and pleased with it and extremely happy with PSA quick and very friendly customer service.
March 11, 2019
As advertised
I put this on a PSA lower with the enhanced LPK.
Fit and finish is great.
Fired four rounds to make sure everything worked, spent cases landed in the same spot and no jams.
Too cold to do any bench work so I will post that later.

Great upper
I put this upper on a Ruger lower and it fit perfect. With a Bushnell scope shoots 55 gr bullets into a inch or better at 100 yards. Good quality would buy again.

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.
