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: 416R Stainless Steel, chambered in 308 WIN with a 1/10 twist, rifle-length gas. Upper is paired with a Palmetto State Armory 15" 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.  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.

Will this fit a dpms lower?
Jason F on Apr 25, 2018
BEST ANSWER: will this upper fit a dpms lower
I would like to put an adjustable gas block on mine. What ones will fit? Thx!
Mike R on Apr 16, 2018
BEST ANSWER: I would think any low profile for a 0.75" diameter barrel would do the trick. I looked at putting one of mine on but frankly I did not need it. It appears the low profile one I have would have been a perfect fit.
Is this compatible with 7.62x51 Nato?
Ron L on Apr 25, 2018

Affordable, Quality
The quality of parts and value are amazing. My pros would be that the barrel looks good, has nice rifling inside. The accuracy is great too given this is a "rack" grade barrel. A good looking upper receiver with t marks that mimics ar15s. Great rail included that is US made. Great lower receiver with no forging imperfections that also mimics ar15 closely. Now the cons: my upper got to me with under torqued screws in the gas block and rail which became appearent after 1 year thanks to only 2 outings. Although barrel nut was in spec I tightened it further to the end of the spectrum for piece of mind. I also gripe about the profile being wrong in the specifications.. this is HBAR you can tell because the profile thickens behind the gas block too much to consider it a2. Besides that its 100% reliable and the only thing I have added is an adjustable gas block which may not even be the case for my reliability being what it has been thus far.

Great for the price.
Good accuracy for a 20" .308, not a bad price either. The rail shipped with mine is ever so slightly canted to the right, but that doesn't matter to me with a scope on the upper only. Heavy stainless barrel, mine was 1.5 moa with ball ammo, have yet to try match.

Satisfied customer!
Fit and finish perfect, over 200 rounds and not a single malfunction. Extremely happy with sub 1 inch groups @ 100 yds.

Muzzle device
After 20 rounds, the muzzle device fell off. Not worried about it, as I will be adding a custom device, but did not expect a manufacturer installed piece to be so loose. Also, there is a high amount of carbon building up at the front side of the gas block, both around the front where it meets the barrel and where the gas tube in exposed. It has not had more than 80 rounds through it yet, so this is a cosmetic issue, but something that should not have to be worried about after a first use.

It is a good rifle but they do need to tighten the rail screws.
I love this upper. But when i took it to the range for the first time the rail came off of the upper. When i did a check of the rail i found that the rail screws were not tightened. i put the rail back on and it worked fine.
