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.

Is this a complete upper? If not what is it missing?
Patrick T on May 3, 2018
BEST ANSWER: It is complete. The only thing I've added is Optics and an MLok rail on the bottom for accessories.
What is the overall length of this upper? Thanks for your help.

Thoroughly Impressed by Value
I bought this rifle expecting to put in a bit of work, and hoping to work my way into 2 MOA groups. I paired this with a Nikon Monarch 3 3-12x42 scope. The rifle and I got off to a rough start. The rifle arrived with a very rough chamber – in fact I could not hand cycle chambered dummy rounds because of a hidden burr near the throat of the chamber. The finish was a little rough – nothing like the more expensive Daniel Defense AR10 variants. Instead of sending this in for warranty repair, I scrubbed it with progressively finer brass brushes before the burr finally disappeared. Next, the rifle was horribly overgassed. Even shooting unsuppressed the rifle launched shells into the stratosphere, and sometimes launched spent brass backwards(headstamp first) into the chamber. Shooting suppressed was exceptionally difficult and thoroughly unenjoyable. At best, I was getting 2-3” groups at 100 yards. Not horrible, but less than I had hoped. After some deliberation, I ended up making two upgrades: a Seekins Precision adjustable gas block and a PSA NiB 2-Stage trigger. These two additions greatly improved the reliability and accuracy of the rifle. I was astounded to be shooting 1” groups at 100 yards with match ammo. Unlike some of my bolt-action rifles, this rifle doesn’t seem overly picky with ammo. The most accurate load I’ve found is Hornady’s 125gr SST Lite.
Overall, I’m thoroughly impressed with this rifle. With a price tag of less than $1000 including upgrades and optic, this rifle is easily able to keep up with many of the more expensive AR10 variants out there. I’ve only put a couple hundred rounds downrange so far, but up this point this rifle has exceeded my expectations .

Good so far
I have only put 100rds through it so far. That said I have shot some hirtenburg and mostly wolf. Rifle functions 100% and locks back on last round. I'm getting 2moa groups with wolf ammo. Very happy with poverty build.

Awesome Upper ! A+++++
I bought this upper to match my Palmetto State Armory Gen 2 lower. It fits perfect, good and tight fit, no wobble or play in the receivers at all. Finish matches perfectly with the lower.

Awesome rifle
Love it. I’m having issue sighting in the scope. I’m not sure if there is additional MOA built into the gun or not. But I can’t get the scope to zero. But I’ll figure that out. Still a 5 star product

What a bargain on a 308!
Great price for a quality ar10 upper with bolt carrier group and charging handle! The lightweight M-Lok handguard is a quality piece also! Well done Palmetto State!

Cheaper to assemble it yourself...
Basically a custom parts gun... couldn't find this setup on the complete PSA PA-10 at the time, so I assembled one myself. ABM.
