Upper:  Precision machined from forged 7075-T6 aluminum, then Black anodize hardcoated to MIL-8625 Type 3 class 2.   

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.

Will this fit a 80 percent arms DPMS lower ?
Zmttb on Apr 20, 2018
BEST ANSWER: Yes it fit mine from NOREEN
Will this fit on a Tennessee Arms 308 lower?
Tyler on Apr 20, 2018
BEST ANSWER: Yes. My brother in-law purchased a complete TNA 308 Lower and a PSA upper. Was a little tight and there was a very small gap at the rear where the receivers meet, but once pinned in, was very solid.
Is the receiver top rail a low profile or high profile?
John C on Apr 13, 2018
BEST ANSWER: low profile
I have a serious concern, will this upper of yours fit my CORE15 5.56/.223?????
BlackHawk on Apr 12, 2018
BEST ANSWER: negative, it will not work with a .223 /5.56 lower
will this fit an 80pecentarms gen 2 308 lower?
B b on Apr 19, 2018
BEST ANSWER: Fits DPMS low gen 2 lower. Gen one or DPMS high will have issues.
What profile is the barrel under the handguard? Is it the same thickness/diameter, smaller or larger, than the exposed barrel? Photos? Thanks.
William B on May 7, 2018
BEST ANSWER: The barrel is thick at the chamber end and then slims down to the thickness of the exposed barrel. It fattens up at the front sight and then reverts back to the smaller diameter that is under the hand guards. It is similar in design to a 16” M4 barrel. This response box won’t allow me to attach a picture. It won’t allow me to send you my email for a pic either. Hope I helped
What do u recommend for a drop in quad rail for this upper?
Scott on Sep 3, 2018
BEST ANSWER: Leapers makes a drop in quad rail for m&p 10 which is what I’ve found to fit for on the gen 2 PSA 10 upper. I didn’t go with a drop in but the keymod rail I went with was for m&p 10 and it fit perfect.
How can I buy a spare set of gas rings for this PA10 upper ?
steven P on Jul 12, 2018
Do you need to purchase anything else to complete the build of this upper if you buy a complete PSA lower also except for a magazine ?
Oldrcluvr on May 2, 2018
BEST ANSWER: All you need is a magazine and you’re ready to go. A complete upper is just that, complete. Very nice stuff and the quality is as good as any high end equipment.
Will this cycle 7.62 x 51 ammo?
Tim K on Apr 17, 2018
BEST ANSWER: Yes, 7.62x51/.308 Rem is what this upper is chambered for.
will this upper snap on to a wyndham arms lower?
torque on May 8, 2018
BEST ANSWER: Hello ; I bought this upper and tried it on a dpms and a warhogg lower without any luck.
I don’t believe it would work with a windham lower , but I haven’t tried . I think the only lower that will work is a pa10 .
which upper will be more accurate, and last longer, this Stainless Steel one, or the 4150V Chrome-Moly Vanadium black nitrate?
D. Graves on Jul 17, 2018

PSA Gen2 PA10 18" Midlength Stainless Steel .308 WIN 1:10 Upper With BCG and CH - 516445344
PSA Gen2 PA10 18
PSA Gen2 PA10 18" Midlength Nitride .308 WIN 1:10 Upper With BCG and Charging Handle - 516445313
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.
Can you take the front sight off?
Derek M on Sep 18, 2018
BEST ANSWER: This has an A2 style gas block/front sight pinned on it with standard military style tapered pins. You can punch the pins out and replace the front sight with a standard .750" gas block if you want to run a 15" free float hand guard. The gas tube (if carefully removed from the A2 sight) is reusable.
Does the front site block view if you mount a scope to rail?
Patrick K on Aug 15, 2018
BEST ANSWER: Depends on the base hight and scope power. With a 4x14 on a med hight riser I don't notice the front sight. With a 1x4 QCB style on a med riser I see a ghost of the front sight in the bottom of the scope at 1 power.
Can you Pin and Weld a Compensator or Muzzle Brake to barrel ? Thanks.
JerseyGO on May 9, 2018
BEST ANSWER: I don’t think you would need to weld one, the standard A2 birdcage is threaded on and with a vice should come off like any other flash hider if you want to check YouTube there are tutorials.... for now...
Will this upper fit a dpms gen 1 lower?
Jason P on Sep 3, 2018
BEST ANSWER: it will and does,with a little modifying. the charge
handle was rubbing on the top of the receiver,had to file that down,also when attatched to the lower,the upper would not fully rotate up with the rear pin removed, had to file the underside of the upper at the front take down pin. all this took about an hour. having known all this ahead of time i would have bought 2nd gen
is this suitable for shooting steel case ammunition ?
Woody on Aug 23, 2018
BEST ANSWER: Yes it will function with steel case ammunition
Does PSA make a Gas Piston Upper in .308?
Joe N on Jun 23, 2018
BEST ANSWER: To my knowledge, no. PSA has all but perfected the AR platform, whether 15 or 10. As such, they are all direct impingement examples. There are companies that specialize in piston systems and that is where I would go to "update" mine if I was of a mind to do so. I am not, however. I was six years an Infantryman and never once did I find the basic rifle lacking. I see no need for a piston system and neither do the majority of the armies of the world. Cheers
will this fit an APF lower?
c s on Sep 2, 2018
BEST ANSWER: Yes it will as long as your getting a AR-10 lower not an AR-15 lower. Also, if your just buying a stripped receiver, your need to watch what bolt catch you buy. The bolt catch can interfere with the assembly of the rifle. It will not be as smooth as a traditional AR-15.
Will this fit Aero precision Lower?
Nissan350z on Aug 30, 2018
BEST ANSWER: I am told that the PA-10 uppers are compatible with all DPMS pattern lowers, but NOT with the Armalite pattern lower receivers. If the Aero Precision upper is patterned in accordance with DPMS specifications,it should work.
Will this fit a PX10 LOWER?
Lyndon on Jun 19, 2018
BEST ANSWER: It will not fit on the PX10 lower. The PX10 is slightly smaller.
Will this fit an Aero Precision lower?
Deaf Jeff on Jul 10, 2018
BEST ANSWER: My understanding is that PSA P -10 uppers might not interchange with other manufacturers' lowers.
will upper fit a utas xtr 12 gauge lower?
key5151 on Sep 17, 2018
Will this fit an aero lower?
Franny911 on May 12, 2018
BEST ANSWER: Frim what I understand no, buy it at your own risk. The pa-10 lower is pretty nice and a great deal. I got my upper and lower shipped for under 500. You will never find that price anywhere else.
Anyone know the weight of upper?

It’s worth the $$
So good. I fired 40 rounds last weekend without a hiccup. I was shooting 1 1/2” groups at 50 yards with open sights. I can’t complain, good product at a reasonable price.

Great upper for the price.
Matched perfectly with a Palmetto lower. 1" groups at 100 yards with federal factory ammo. No failure to feed or failure to eject.

value for money
I bought this 2 months ago, have put through just over 300rds . So far have had only 1 jam (failure to fully extract empty case)
I have 3 different brands of magazines ,all function perfectly.
Recoil is mild for a 308. Fitted a 3-9 scope , going to go less magnification next time. Am going to buy another.
