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.

Solid Budget Option
I've had this upper for a over a year so I figured it was time to give it a review. This upper sits on top of a PA10 gen 2 lower I built with a Magpul MOE lower build kit I also got from PSA. Only upgrades I've done to it are a Primary Arms 4-14 ACSS optic and a Larue MBT 2-stage trigger.

From the factory the rifle DEFINITELY needs a break in period. Charging handle and BCG were sticky and tuff to manipulate. Took about 30-50 rounds for mine to smooth out. I did a lot of research online about other people's reviews and one thing a lot of people were saying was that the PA10 tends to be slightly over gassed. I have very limited experience with AR10s so I can't really speak to that. What I can tell you is that the AR10 BCG is SIGNIFICANTLY heavier/beefier than one in an AR15, and thus has noticeably more recoil. Welcome to large rifle caliber shooting.

Now as far as accuracy goes I've very pleased. I have shot the Federal M80 surplus and was about 3 MOA at 100 yds. But I wanted to squeeze out every but of accuracy so I fought a box of serveral different brands and offerings. Bought Federal, Magtech, IMI, and PPU. Best group i shot was a 3 round group from MagTech's .308 Sniper 168 gr BTHP ammo, .508 MOA at 100yrds. Federal GMM was getting me about 1-2 MOA. I'll be doing more testing with the MagTech load in the future.
Hard to be mad at that group.
