The Gen2 PA10 receivers are functionally compatible with the Gen1 upper receivers; however we recommend matching Gen2 lowers to Gen2 uppers for best appearance.  There are external cosmetic differences when mixing Gen1 and Gen2 upper and lower receivers that some may not find appealing.  Gen1 lowers will be available in the future for those who want a cosmetic match. 

The AR10 platform does not enjoy a common design between manufacturers, like the AR15. As a result, there can and will be subtle differences in the parts kits of various manufacturers. Some parts, like the fire control group, are shared with the AR15 platform to preserve the options for upgrading. For best results, we recommend only using PSA PA10 parts with our uppers and lower receivers. We do not recommend using other manufacturer’s parts in our products.

I have a regular 308 lower from Tennessee arms, this will fit it right?
Robert on May 3, 2018
BEST ANSWER: yes it will fit this is a regular upper just has a free float rail witch doesnt effect anything I assume you have a ar style lower .if it is a ar style 308 it will fit.
I have a dpms lower lr-308 will this upper fit?
Ron B on Jun 17, 2018
BEST ANSWER: you may have missed it in the description. the upper may technically fit other lowers but it isnt guaranteed to be a perfect fit unless it is a PSA lower. the upper is a dpms style so you should be good especially if the lower has an adjustment screw.
Will this upper fit a polymer 80 .308 lower dpms style?
Marcus A on Jun 16, 2018
BEST ANSWER: Yes as long as lower is mil spec or tolerances are mil spec.
What is the inside diameter of the handguard?
Sageman on Jun 8, 2018
BEST ANSWER: I never got the gun. still looking for one .will buy in two piieces up and lower
Will this fit on a regular AR 15 lower?
Corey C on Jul 22, 2018
BEST ANSWER: No, will not fit. Also, Larger caliber mag will not fit in at-15 lower. Smaller caliber round might not work properly with larger bolt and barrel. Likely to be safety issue.
Is this compatible with the gen 2 pa10 complete lower? And will this fire military ammo with no problems?
terry b on Jul 31, 2018
BEST ANSWER: Yes it is compatible.. They are made to work together. I purchased the same set-up as you and im completly happy with it. The only issue I had with the blem upper was the the muzzle break on it was clocked a little off. I added a spacer I had from my .308 AK and it lined up perfectly. I believe the gen 2 lower also works with the gen 1 upper as well but has some cosmetic difference ie. lines not matching up.
Similar to the question asked previously, I have a 308 lower from primary weapons systems. I am wondering, will this upper will fit it? I understand that not all "AR-10s" are built to the same specs, but I like PSA products and would like to match this to my lower.
cream of wheat on Jun 15, 2018
BEST ANSWER: I have an Aero Precision 308 Upper and Lower, as well as a PSA GEN2 308 Upper and Lower. My PSA Upper does NOT fit my Aero Lower, but my Aero Upper DOES fit my PSA Lower. Hope this helps you.
Will this fit an M5 Aero Precision .308 lower?
Jr M on Jul 15, 2018
BEST ANSWER: hmmm, looks like they don't work together from what a couple of people have tried. they just dont line up right, so I would say No.
Can you ship this to Maryland?

I bought this upper to go with the PA10 lower. It said that the upper was a blem, you couldn't prove it by me. The upper looks as good as the lower, and combined is a super rifle. Thanks again Palmetto Armory. David Kalbfleisch

Very impressed!
I purchased this upper over fathers day and mated it to the lower I had bought previously. Fit and finish is great, like most other reviewers I couldn't find the blemish. I did have to tighten up the handgaurd as it was a little loose. I just got back from a long range shooting class and was able to consistently hit targets from 400 up to 1000 yards. I had no problem hitting the 8" target at 700 yards. I was also able to hit the 1000 yard target on my first shot. With Match ammo this rifle is extremely accurate! I was using 175 grain Sierra Matchking. Went through 100 rounds at the class and 60 round of surplus ammo before the class with no failures.
1000 yard target. To the right of the close big tree way back in the woodline.

Nicely crafted upper!!!
I bought this upper less than 2 weeks ago. I received it a week ago. Shipped fast, and no noticeable blemishes that I could see. I could only see one area that might be considered a blemish because the black coating had a few VERY minor spots that weren't as flat as the rest. Nut that was it. Overall very impressed and I have received quite a few compliments on it.

BLEM PSA Gen2 PA10 18" Midlength .308 WIN 1:10 Stainless Steel 15" M-lok Upper - with BCG and CH -516447164B
Glad I gave PSA a second chance..I assembled a PSA AR-15 kit gun & had some problems with the upper. Decided I was through with PSA products..after a year or so, changed my mind & bought this upper. Paired with a PSA Gen 2 lower, it's been functioning perfectly for several hundred rounds. I'm satisfied with my AR-10..& seem to have worked out the bugs in my PSA AR-15.

Have been unable to find any blemishes on my upper, it shoots quite well, and have had no issues @ all with the upper or lower than I purchased. I would recommend this upper to anyone wanting an AR-10

Exceptional Value!!!
Really nice upper! I did find what I believe is considered a "blemish" but it took a while. Very slight discoloration about the size of a dime on the upper receiver. Shoots right at 1moa with the PA10 lower. Over all I couldn't be happier and will continue doing business with PSA!
