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.

PSA Gen2 PA10 18" Midlength Nitride .308 WIN 1:10 Upper With BCG and Charging Handle - 516445313
PSA Gen2 PA10 18
PSA Gen2 PA10 18" Midlength Stainless Steel .308 WIN 1:10 Upper With BCG and CH - 516445344
BEST ANSWER: You will see about the same for round count durability. The stainless accuracy will fall off quickly when the barrel wears out as the vanadium will lose accuracy slowly over time. With proper care either will last a minimum of 8 to 10 thousand rounds. Accuracy should be about the same for both.

Impulse satisfied!
Rode down to Mt. Pleasant store to get AR parts for a build and got to talking to Ken, who I deal with a lot. He asked me if I was still looking to build a 308 and I said of course, what 've you got? He informed me He had a billet lower Gen2 EPT A2 left that was on sale online and an upper on sale as well. I said let's look at them and He pulled them out. The billet lower was impressive, well machined and a nice rubber PSA grip, which I prefer over the Magpul.The EPT was slick, as usual, and I use them on all my guns! The upper was outstanding as well.basic AR 10 with F2 front sight delta ring and stock but a really nice nitrided barrel. FYI, when PSA says nitrided, it seems to be the QPQ process as opposed to their Melonite (which is a brand name process).The Melonite is a duller, gray/black while the Nitrided is a satin black (much nicer, imho) Ken was gracious enough to match the online prices,so I left with the lower for 179.99 and the upper for 279.99. Got it home and put a Magpul mid-length MOE handguard on it and a Magpul Pro rear sight. Using Armscor 168 gr. FMJBT, I got it zeroed at 75 yards, hitting center mass of a 9' foam pie plate. It shoots an average 2.5 inches with iron sights! Insignificantly better, like 2 inches, with a Romeo5 red dot. With better ammo and a real scope, this thing should be a bear! Pretty work, PSA,pretty work! Semper Fi.
