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 am s felon can I purchase the Blem PSA Gen 10 upper?
Kim b on Jun 12, 2018
BEST ANSWER: OK. Here is how you do this legally. Place your order, and pay with a credit card. Put my address, not yours, in the "ship to" column. Now, you have the thrill of buying this upper, but you are not putting yourself at risk. I promise to make good use of it, and I'd be happy to send you pictures. You're welcome!

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.

It would be nice if there was some sort of matrix to show what's different between uppers with the same descriptions but different part numbers. (?)
Doug L on Dec 7, 2018
BEST ANSWER: They have slight differences , Like different barrel coating, material, makers, etc
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 on a regular AR 15 lower?
Corey C on Jul 22, 2018
BEST ANSWER: No. The AR10 platform is larger than the AR15 platform. They aren't interchangeable.
Can you use 7.62 x 51mm safely with these uppers?
Cbass on Jan 26, 2019
BEST ANSWER: Commercial. 308 is loaded to higher pressure than 7.62 nato, so using the lower pressure cartridge, will not be an issue. I interchanged both on a regular basis with no I'll effects.
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.
Is this upper offered with a keymod hand guard ?
Nelson B on Feb 14, 2019
BEST ANSWER: These are blemish runs I’m fairly sure they won’t replace the guard unless you call and request it as a custom build you can find a key mod guard and install it after you verify the smooth operation of the upper and it will probably less expensive then a custom build plus you will have an extra guard.

Nicholas M on Nov 4, 2018

Great upper. Looks great too! I can't find the BLEM... My only complaint is my fault... I wish I had waited an extra day or so to buy it because the 20" with rifle length gas system came in stock for $10 more. Meh, such is life, amiright? Buy this thing if you can. It'll eat whatever you feed it and it'll reach out and touch whatever you point it at. Happy shootin!

PSA parts, products, and service
I have about 8-10 complete PSA rifles, all of which are composed of mostly “blemished” parts... I have never had a single malfunction or misaligned part out of all of my orders... some of the parts are mates to other manufactured parts and I have had no issues with calibers ranging from 9mm, 5.56, .300, and .308... this company offers an exceptional value at its cost and I will continue to use and recommend their products... shipping and customer service have been what is advertised, prompt and courteous in all cases...

Blemished ?
I think PSA just labels things blemished to sale it at even lower prices. I'm yet to receive a so called blemished anything from them that is actually blemished. Great products at unbelievable prices. Keep up the great work.

AR10
Got this a few weeks ago and then my lower last week. Never notice any "blemishes", it looked great to me. Went to the range and it shot like a dream. It ate everything I had, new, reman, even some Tula and NO hickups at all. Very impressed. Sighted in nicely on BUIs and with my scope it was easy as pie!! I like PIE!!

Happily Surprised
I held off writing a review until I had a chance to really put it through the paces. First off it shipped and arrived quickly. About a week from ordering it was on my porch. The blem I found was a very small "scratch" under the forward assist at the hole for the roll pin. Fit my Aero Gen II lower well. I gave it a good cleaning and re-oiled with a quality lube. It functioned well and locked back when I tested it with dummy rounds. I loaded some mild loads for initial testing. I very soon found that even with these very mild loads, I was getting pronounced ejector dimples on the brass.I found the ejector to be very hard to depress, much harder than any other AR-308 bolt I've tried. I put some penetrating oil on the ejector and used a spent shell case to repeatedly depress the ejector. After 30-40 times pressing it in, I felt it break free. I think there was a burr on the ejector that finally smoothed down because now it works perfectly. I assume this would have work itself out during break-in, but didn't want damaged brass..The rifling looks well cut and the crown is fine. The feed ramps were a little rough, but it feeds well. It locks back every time on an empty magazine, and the ejected brass only has minor marks. It took around 40 shots for the barrel to settle in and start grouping. It does not like to be perfectly clean! I used 150 grain Gold dot bullets and CFE-223 powder and without much load development, it's more than capable of 5/8"-3/4" groups at 100 yards, probably even a little smaller with more time developing a load. At about .5 grain under max of cfe-223 the 150 grain bullet was running right at 2750 from the 18" barrel. I'm very happy with the upper and would recommend it anyone looking for a decent upper that's easy on the wallet.

Better than expected
Upper arrived promptly. The blemish was very minor. Mated it to a BSA lower without any problems. Gun fired and cycled normally through 20 rounds on the range. It shot about one inch groups using 165 grain Hornady SST at 100 yards. I was sighting in a thermal so my experience may not reflect the full consistency/capability of the barrel. After one trip to the range I'm confident that if I don't hit what I'm shooting it wouldn't be the upper's fault.
