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 manufacturer’s parts in our products.

Is there a problem using this upper with an aero lower? I seen some people say that psalm don't fit but only on a psalm lower.
Elio R on Apr 13, 2018
BEST ANSWER: Their is no standardized system for these. They will all vary between the producing companies. As of now. So it is best to buy the upper and lower from the same manufacture. PSA 10 has exceeded my expectations!

Fit and finish are good, runs great (on a factory complete PSA lower) without a suppressor, wwwaayyy over gassed for a can. Wish it had come with a adustable gas block. Otherwise, no complaints

Surprisingly pleased
I recently purchased a completed upper and lower PA10 from your online store. This was my first purchase from your company and as such as I do with any new large purchase I did my due diligence and researched your company and products.
I was somewhat off put at first due to the proliferation of complaints I ran across. specifically issues arising from long shipping times, quality control issues discovered with products, and poor customer service.
The issue of shipping times I found no issue with prior to purchase since it is clearly stated on your website to expect up to 15 day before shipping. Anyone who finds fault in that is clearly to ignorant to read directions fully and thus their opinion holds no value to me.
As far as customer service is concerned I had little involvement with that section, with the exception of sending one email asking a compatibility question, which was answered promptly, politely, and satisfactorily.
The aspect of quality control and over all quality of the product was my final hurdle to overcome. I decided to judge it on my own and as afore mentioned purchased a firearm through your online catalog.
Now that I have received my order I have a few things that bare sharing with your company.
--- The shipping time was AMAZINGLY fast. Even though two plus weeks were stated as possible shipping times, I received my complete order consisting of two separate orders with in FOUR DAYS!
--- Shipping doesn't matter no matter the speed if you are just getting a poor quality product... Once I received my orders I thoroughly disassembled, checked over, oiled, and reinstalled each part. I looked over each and every aspect of the item. I inspected the firearm with more scrutiny than I normally do simply due to the fact that quite honestly I was looking for a fault. Well Palmetto... I didn't find a single blemish, not an un-oiled seal, not a scuff in the coating, not a loose pin. I expected some fit an finish faults given the "budget" price.
Damnit Palmetto I can not find a single flaw... I ran a couple magazines through the gun, sighted in my optic and tore it all back down to find no issues anywhere. I LOVE this weapon!
I found the fit and finish to be better than some military spec ARs that I own.
In summation let me say I have never been more happy with the purchase of a firearm than I am with this one. From price to customer support to shipping and over all quality I am 100% satisfied and will be a repeat customer for years to come.

Great for the Price
Looked great right out of the box. packaging was great and shipping was good. Lead times weren't the worst I have seen. I have only run into one issue so far. my third time bringing it to the range, the gun wouldn't cycle. I needed to lubricate the inside of the upper receiver and the BCG to get it to cycle. not sure if my ammo was a little light, or the BCG was a little too snug. could also have been some really dirty ammo. I have never had this happen with around 50 rounds through a receiver. this is a very small issue, and I would definitely recommend this product and company.

Great upper
Love the upper. Matched to a PSA A2 lower and so far it's fantastic.
