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 manufacturers parts in our products.

Best LFAR buy I have made so far. Near match accuracy with factory ammo.
I purchased this upper and a PA-10 Gen2 MOE lower to replace my Springfield SOCOM M1A. The M1A is a decent gun, but is way overpriced and heavy. And I had to do several things to get MOA accuracy even with handloaded ammunition. And it's heavy. About 3-pounds heavier than my PA-10.

I have several PSA AR-15 rifles and wanted to try a PA-10. Couldn't be happier that I did. I have performed no modifications or upgrades to the upper other than a scope and mount. Sub-MOA accuracy with Hornady American Whitetail SP ammo like it came. This upper produces 5-shot 3/4" groups at 100yds, with a Bushnell Trophy XLT 3-9 scope on an Aero mount, shooting from a steel bench with front and rear sandbags. This is hunting ammo, not match ammo. No handloads have been attempted yet. There has been no need to with my results.

Purely based on the $400 price tag for a truly complete upper I was not expecting this to shoot as accurately as it does with factory ammo. I have paid much more than that for just a match-grade barrel for my other LFAR builds. My expectations included having to work up a load that it liked, as well as putting an adjustable gas block, and spending lots of time, money, and effort in the process to get MOA accuracy and reliability. Not sub-MOA. Worst case scenario for me was upgrading the barrel to get the results I wanted. What I got was the best case scenario, actually better, with a shooter right out of the box.

Bottom line, you can get 3 complete PA-10 rifles, with decent optics, for the same money as I had in my M1A after the necessary upgrades to get it to shoot well. I sold my M1A after shooting this upper the first time and have no regrets.

WOW this was well worth the time and money. Little worried over gen one issues. Guess what? Gen two is phenomenal!!
Got this upper and paired it with gen two lower with overmold grip. Sweet combo!! Shot it 10/18/2017 for the first time. Ate everything it was fed. Nato 149 grain FMJ and Tul steel case 150 grain FMJ. NO failures to feed or eject
with 85 rounds fired. Very very pleased with this setup. Want to buy another LOL. Oh buying upper and lower seperate saves money VS buying complete AR-10 from Palmetto. Who doesn't like saving money?? Nuff said. WOW

Outstanding Value
Paired with a PA-10 Complete Lower with EPT. Optic used is a 4-12x40 .308 BDC scope magpul mags. Shot 50 rounds of 147gr. FMJ to break in the barrel. Most groups were touching each other with a few fliers. No failures of any sort. Shot 20 rounds of Malay surplus flawless tight groups. Last shooting was with German MEN '93 surplus at reasonably rapid fire with a 6mph crosswind and 12mph gusts nice 2MOA cluster with most shots touching. Very excited to see what it can do with better ammo. Function was flawless and inspection after shooting showed nothing out of the ordinary. Outstanding value thanks PSA.

Beyond satisfied with PSA.
I am more than happy with the purchase of my PSA PA10 upper that locked up perfectly with my PSA PA10 Gen2 lower receiver. The fit and finish look amazing. Honestly as good as higher end rifles costing 4 times more. Even my FFL guy who has been in the business for over 50yrs was impressed with my PA10. Everything functions flawlessly. The only non-PSA part I used in my AR10 build was the Sprinco extra power orange buffer spring and a aftermarket drop-in trigger that improved functionality. As long as you remember that not all AR10 parts are interchangeable as the AR15 parts are you will be a happy gun owner. I know I am!

This thing is accurate and consistent with all .308 and 7.62 NATO rounds I've put through it. One of the most accurate rifles (mated with gen 2 lower). I have ever shot. Eats anything you feed it including cheap Wolf .308. A complete .308 AR for under $600 shipped unbelievable!!!

Fit and finish are excellent. Locks up like a vault with my PSA Gen2 lower. The BCG with the nitride finish is slick and free of tool marks. Can't really beat this gun for the money I'm impressed all around and have been with PSA. Also the shipping was very fast.

100 rounds in no problems at all
Overall very happy with my purchase light lube on trigger group and heavy on the BCG W/ Mobile 1. Running GREAT!!!

Update to 5/13
Rifle is doing everything well.

Well over 150 rounds so far. Spent last weekend hitting steel plates out to 700m. Under 300m it has sub MOA accuracy and doesn't really begin opening up until about 650 still under 1.5 MOA.

It definitely has a preference for 168gr rounds and makes a nice clean pile when shooting. Functions fine with a full assortment of 146-175s both factory and handloads.
