New and improved Palmetto State Armory PA10 Gen2 308 Upper is fully assembled and ready for your complete PA10 Gen2 Lower!

With streamlined styling and improved function, the new and improved PSA PA10 is here.  The Gen2 model offers an enhanced chamber and extraction, with a more modern appearance.  

Barrel: Machined from 416R Stainless Steel barrel.  Barrel is chambered in 308 Winchester with a 1:10 twist rate and operates with a rifle-length gas system.  Upper is paired with a Palmetto State Armory 15" Lightweight M-Lok free-float rail, low profile gas block, and an A2-style muzzle device.

Upper:  Precision machined from forged 7075-T6 aluminum, then Black anodize hardcoated to MIL-8625 Type 3 class 2.   

Bolt Carrier Group:  9310 steel bolt assembly, nitride treated for durability.  8620 carrier, nitride treated, with a nitride treated gas key properly staked with grade 8 fasteners.  Charging handle is also included.

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.

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.

Is this upper compatible with dpms barrels?
Matthew G on Jul 16, 2018
BEST ANSWER: When I emailed them, the answer I got was "While the PA-10 platform is loosely based on the DPMS gen1 profile, we can only guarantee the fit and function of PA-10 parts to other PA-10 parts." So far, I haven't tried anything else, but DPMS style mags fit and function.
Compatible with 80 Percent Arms Lowers?
Kenobi Prime on Jul 23, 2018
BEST ANSWER: Mostly Yes, slightly No. An AR 10 is not like and AR 15 in that you get a lot more variation in the AR10, where an AR 15 is almost always interchangeable parts. Now since your are making this 80% lower for the AR 10, this makes you the manufacturer of the lower and you can make your AR10 fit whatever you want it too. This being said if I were you I would buy this upper and then make my lower match it. I lover this upper and now so do 2 of my friends who also bought this upper. I would build to fit this upper.
Is this upper compatible with a aero m5 .308 lower?
Randy C on Jul 31, 2018
BEST ANSWER: I didn't realize the AR-10s aren't mil-spec like the AR-15s until after I bought this upper. I tried this upper on 3 different lowers that my local gunshop owner had and none of them were compatible so I ended up ordering a PSA lower and it worked perfect. Very satisfied with the gun.

Jim M on Jul 10, 2018
BEST ANSWER: Yes there is one wrench with multiple sizes that you can get , i wanted to do the same to put a lighter barrel myself.

Exactly what I was looking for
At a great price. Like everything else I’ve purchased from PSA, it is top notch

My son just purchased one of these AR-10's. What a fantastic weapon. As a near novice shooter, once the weapon was zeroed, my son was able to achieve groups that fit under a quarter. The first time and every time I have fired this weapon I have groups that fit under a dime. The max distance we have been able to shoot at this time is 200 yards. We will next find a 500 yard range. As a retired Army sniper this weapon has my complete endorsement.

Good complete upper for the price. Only problem was a little bit of play when matched up with the PSA lower that I previously purchased.
