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.

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.

Assembled well and runs great!
This upper was cleaned and installed on a lower and shoots great! No failures of any kind. XM80 groups 2 moa but 168gr Federal Gold Metal Match groups MOA and 175gr FGMM groups sub MOA at 100 yards. This upper likes heavy bullets. Odin Gunworks adjustable gas block fits easily under this hand guard. It was over gassed but the adjustable gas block fixed it with ease. 300 rounds fired so far and no issues.

Awful first impression.
So far I don't like Gen2 .308, because the charge handle didn't pull back smoothly, then once it did work it tried loading a second bullet in the chamber. So I took it apart, talking about the charge handle and BGC and put small amounts of gun oil. The Charge handle was smooth on recoil, but BGC started to stick and now I can't load anything because the firing pin won't retract.
I'm not impressed with the product right now.

So far, has met my expectations.
Fits well with the PSA Gen 2 lower. Cosmetics were excellent. Functioned flawlessly. But I have not been able to shoot groups yet.
