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.

Lower Build Kit: PSA PA10 ACS-L lower build kit with PSA Overmolded A2 Grip.  Everything you need to turn your PSA PA10 stripped lower into a complete lower.

  • 7075-T6 Forged aluminum receiver
  • 18" 416R Stainless Steel barrel
  • .308 WIN Chamber
  • 1 in 10 twist rate
  • Mid-length Gas system

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.

Will this fit a DPMS Gen 1 lower?
Jason S on Apr 21, 2018
BEST ANSWER: PSA only guarantees their PA-10 uppers work on their PA-10 lowers. I've heard that they have a couple proprietary parts.
I have a Aero Precision M5 ar10 stripped lower. Will this work on it ?
Scott B on Apr 24, 2018
BEST ANSWER: NO!!!! They do not fit.
Does this come with instructions to build the lower?
DRIVER on Apr 24, 2018
BEST ANSWER: YouTube has dozens of build videos, but instructions have my been included in the kids I've purchased.
Does the upper come assembled?
Michael L on Apr 21, 2018
BEST ANSWER: The upper should come assembled but you will have to put the lower parts on with your stripped lower.
Is the AR10 SKU 516446761 a complete kit or do I need to gather more parts?
Charles S on Jun 26, 2018
BEST ANSWER: You need a stripped lower as well, i would suggest a stripped lower from psa because aero and many other stripped lowers won’t fit correctly
Is the buffer tube mil-spec or commercial diameter?

Best value in the market!
Purchased this to complete a stripped gen 2 lower. Put my first 20 downrange today and it ran flawlessly. Accuracy was very good but to be fair I was at an indoor range so I wasn’t exactly reaching out. Majorly impressed by Palmetto once again they make a solid product for the dollar!

Great way to get into an ar-10
I purchased the complete upper with lower parts kit and a stripped lower from PSA. It all went together great. So far only 20 rds downrange with it but it seems to shoot very well.

Shoots GREAT! I am very happy with the product and price. Thank you PSA :)
Everything is fine except that the kit came with the incorrect take down pin. I didn't want to go through the hassle of trying to prove this fact, so I simply ordered a correct pin from PSA and all is well with the rifle.

Maximum value
This was my first AR purchase. I've shot some expensive ones with buddies prior. This gun shoots great! I honestly don't notice any difference between this AR10 and much more expensive ones. I paired this with a stripped psa lower. It's incredibly accurate. I would definitely recommend buying this gun.

To better serve future customers, it would be most helpful, if u provided magazines with the build kit.

This gun is a shooter. Made my own lower and assembled and have had nothing but fun ever since. Went together easily with no problems and has preformed flawlessly.
