Will this fit a 80 percent arms DPMS lower ?
MGreen on Apr 20, 2018
BEST ANSWER: Yes it fit mine from NOREEN
I have a serious concern, will this upper of yours fit my CORE15 5.56/.223?????
BlackHawk on Apr 12, 2018
BEST ANSWER: Absolutely not. This is an AR10 upper, chambered in .308, not an AR15 upper chambered in .223/5.56. Will not even fit on the lower, much less chamber a round.
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
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 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.
Anyone know the weight of upper?
Jamie F on Jul 5, 2018

How can I buy a spare set of gas rings for this PA10 upper ?
steven P on Jul 12, 2018
which upper will be more accurate, and last longer, this Stainless Steel one, or the 4150V Chrome-Moly Vanadium black nitrate?

PSA Gen2 PA10 18
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.
What profile is the barrel under the handguard? Is it the same thickness/diameter, smaller or larger, than the exposed barrel? Photos? Thanks.
BillB 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

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

Will this upper work with a Anderson AR-15 5.56 multi-caliber lower?
johnnie on Sep 26, 2018
BEST ANSWER: No, this will absolutely not. The PA10 is for an AR10 platform. PSA has the compatible lower and it is very nice.
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 this upper fit with other lowers other that PSA?
adrian on Oct 24, 2018
BEST ANSWER: I don’t know if it fits other lowers and it says it only fits their gen 2’s lowers without any misalignment issues.
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...
Do y’all carry a complete upper to fit your PA-15 multi lower ?
David I on Nov 29, 2018
BEST ANSWER: Hi I have one of these on a NOREEN 80% lower, it took a very tiny bit of sanding on the rear pin area and it works great. would buy one again if needed.
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 308 upper fit on an Aeroprecision lower?
Kenneth M on Jun 1, 2019
BEST ANSWER: I fit mine to a PSA lower perfect fit. If The Aeroprecision is DPMS patterned it will not fit. The AR 10’s do not have 1 spec.

Pleasantly surprised.
The charging handle is hard to grab with my giant hands. Other than that I am happy.
Ordered lower at Easter sale and upper at 4th of July sale. Matched well.

A great “go-to” all around hunting rifle...very impressed!
Very impressed with this upper. Cleaned it, mounted an inexpensive Nikon Buckmasters scope on a 1”riser, purchased a variety of ammo, and headed to the range. After running about 20 rounds of cheap stuff through it, I ran a bore snake through the barrel and started dialing in with the hunting ammo. Unbelievably, it liked the cheapest ammo stuff I had...Remington Core-lokt 150 grain.
This upper loves Remington Core-Lokt 150’s.

Great product for the money, can be improved though
I was dubious of the reliability and accuracy when I started reading reviews on forums of this upper, I don't regret the purchase one bit. I'm guessing people in the past had issues with the gen 1 uppers, there were a few issues I had to iron out on this gen 2 upper tho. The bolt catch contacted the bottom of the bolt carrier upon cycling, small amount of filing and it was flawless, taking it out to the range the first time I was frustrated due to ftf issues with brass case ammo, upon further inspection there was a small burr on the front of the bcg that was never smoothed from the factory, small amounts of sanding and the reliability has been flawless since My lower also had the buffer tube unscrewed one thread too far causing the bcg to hit the lower. The best upgrade for accuracy I did was bedding the factory PSA 18" ss barrel into the upper with loctite on the barrel extension, groups at 100 yards shrunk from about an inch and a quarter to around 7/8 of an inch with a best group of the day measuring in at .678 with a flier on my part! If you like tinkering and squeezing everything out of something one of these uppers is impossible to beat. I may be OCD, I did have to fix some small issues, but I didn't buy a 2k$ gun for a reason, and mine seems to shoot as good, if not better than some of those more expensive offerings.
