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.

Can a Faxon barrel be used with these uppers?
Tommy on May 7, 2018
BEST ANSWER: From what I've read on forums yes,but you should get a faxon bolt or head space will probably be off. I don't remember the forum but a little bit of searching and you'll see the individuals experience, faxon will not guarantee headspace with any bolt than theirs long story short
Has anyone used this upper with a 308 Polymer 80 Lower?

Is this chambered in .308 or in 7.62 x 51?
RickJ on May 9, 2018
BEST ANSWER: the listing on PSA website says .308, but I have fired both .308 and 7.62x51.. these two are the exact same size cartridges but .308 is higher pressure than 7.62...but both work fine in this rifle.

Awesome Upper
This came to me in three days... It was spotless. I did have to lube it, it came dry. Finish was perfect.
Purchased the lower separately, perfect match.
