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 headspace already verified on these completed uppers?

BEST ANSWER: Yes, but be careful of what lower you use.
The one I have had a few alignment problems I had deal with.

Absolutely great upper, buy it!
I bought the lower and upper separately as "blems". however, my original upper was the melenited version. I had some performance issues with it and contacted PSA and they had me send it back. PSA confirmed the problem and replaced it with the upgraded stainless. I took it to the range today(06/16/2018) for the first time. Sighted it in and was was hitting on target @300yd. I did add a muzzle break and the recoil was drastically lower. Worth more than what you pay.

Great deal
Workmanship appear excellent. The BCG is quality, and accuracy was 1-1.5 MOA with cheap ammunition.

Ran a couple of patches down the barrel, mounted a scope, oiled the BCG and sighted in. Once sighted, shot 2 three shot groups at 100. I shot one, my cousin the other. .619 and .625. Used the only 308 ammo I had at the time, Federal 150 soft point. The lower has the PSA two stage trigger. That seems to be pretty decent as well. I look forward to actually working up a load for this!

Enjoying my PA-10 20” barrel
Haven’t been out further than 100 yards yet, but being a novice in the field of long range, scoped rifles, I shot a 3/4 inch group.

Haven't shot it yet as I just got the scope on and letting the locktight set on the screws, but the fit and function is excellent!! Very hopefull for accuracy and functionality of weapon.

Solid Upper
45 rounds through so far and functions flawlessly and doesn't seem overgassed at all. Smooth shooting and no blemishes. Would buy again and again with complete confidence.

Everything I was looking for at the right price. No need to pay more for the same quality. Consistent 1” groups at 300 yards. Two thumbs up 👍🏻 👍🏻

Fit and finish were very nice. Accuracy left something to be desired. Even after the cost of a barrel change the price was still economical.
