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.

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?
Michael H on May 15, 2018
BEST ANSWER: this will work on a polymer 80%, handles fine
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.
Does this handguard have m-lok on the bottom as well? Would like to put a bi-pod on.

What is the meaning of: 'Barrel Finish: Natural' on contraposition of stainless steel?
Reynel F on May 15, 2018
BEST ANSWER: "Natural" indicates that there is no finish or treatment applied on the stainless after it was turned. The barrel finish is just short of what I would call 'brushed', although personally I prefer it.
Do you have a bi pod that will fit this?

First five shots
This upper is actually a blem although I never found it.

The upper was mated to the PSA 516446483 lower with the EPT trigger. A Primary Arms 1-6x ACSS Raptor held by and Aero Precision mount was on top. The scope was literally bore sighted by looking through the bore and the scope to get close. The Raptor is sighted 1" high at 100 yards for BDC calibration.

The rifle was unboxed and slapped together without any ceremony other than making sure that there was nothing in the bore. The scope was attached, leveled and torqued. Nothing was greased, the bolt was never removed from the upper. It was run as it was received.

It was loaded with 150gr UMC Remington, 2820fps blk ammo.

The first round was left of the target three inches, perfect 1" high elevation @ 100 yards. The elevation was just luck. 12 clicks right. This was on steel.

The second round hit perfect, 1 inch above the target, again on steel @ 100 yards.

The next three rounds were the group you see. Center to center is 1.125"

1100' elev. 85 degrees in the shade. 100% humidity.

Shooting was prone from a Luv's diaper box.

Have a nice day.

Great AR10 upper!!!
Great value for someone looking to get into a AR10 without breaking the bank. Accurate, and functions as it should. Fits well with the PSA lowers. Can’t beat the quality for this price. Very happy with PSA products!

Simply Awesome!
Flawlessly coupled it with a PSA lower, Magpul adjustable stock, a Limb-Saver recoil pad and a Armaspec Stealth Recoil Spring.

Sweet shooting and more accurate than I can shoot.

A bit on the heavy-side but that helps with the recoil. I wish I had come to PSA when I procured my first AR10.

Great value
Bought an 18" PSA 308 Gen 2 along with the 308 classic lower and I am very impressed with the quality and the price.
So much so that I just ordered a 20" upper and another classic lower so my wife can have her own 308, 18" of course.

Nice starter upper.
I am still breaking this upper in, accuracy has been so-so. The price is attractive enough that I can swap the barrel and I am still ok. Nice fit and finish for the price point.
