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: 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 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.
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
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
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.
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: it cycled Malaysian 7.62x51 i bought on sale. i also used some PPU, Federal, and 1 i cant remember right now. it also ran PPU 168 match with zero issues.
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 .
Will it fit a DPMS Oracle receiver for 308?
MikeS on Nov 28, 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
Is this barrel dedicated to the sight/gas block? Does the barrel have the two divots where the roll pins go to secure the sight/gas block to the barrel?
mghtyms04 on Sep 28, 2018
BEST ANSWER: The barrel has the grooves drilled onto the bottom of it where the tapered pins go into it , to hold the gas block on securely. It is built very well. I removed them and installed a low profile gas block for the low profile hand guard. Hope this helps.
I have a sig swat 223 . Will this fit that?
Jim B on Sep 22, 2018
BEST ANSWER: No You need the PSA PA10 lower or similar 308 lower
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.
I have a GO Ballistic Lowe. it uses DPMS low, parts. will this work with this upper?
dannyringo on Sep 20, 2018
BEST ANSWER: I don't think it will. I tried it on an aero precision with no luck. I still have this upper with no lower that will fit. PSA only recommends their lowers...
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 a polymer80 lower?
Jlewwwwww on Nov 20, 2018
BEST ANSWER: I have never used a Polymer80 lower for an AR 10 build. You might want to contact the manufacturer and ask if that lower has specs that work for the upper. Good luck.
Will this fit the Armalite AR-10 Lower (1998) ?
Rafael P on Oct 8, 2018
BEST ANSWER: No. DPMS style lowers I believe.

A tack driver!
I wanted a long range .308 and considered getting a bolt action for the accuracy, but I also wanted to carry it deer hunting (not from a stand) and after researching the cost of building a semi-auto PA-10 in .308 and saw that I could do it for about the cost of a nice bolt action I went with the PA-10 and I'm glad I did! I put this 18" stainless 1 in 10 twist .308 upper on a Palmetto lower that I built from a stripped receiver and mounted a Vortex Crossfire II, 3-9 power scope on it and this gun is a Tack Driver! It took just 2 rounds to get it zeroed and then I was shooting 1" groups at 100 yards with it on a bipod! I lightly buffed the "newness" off the bolt with a green pad just to get rid of the scratchy feel when I cycled it. I lubed it lightly with some Break-Free and fired 60 rounds through it so far without a single jam or ejection issue! I love this gun! I never thought I would get the accuracy of a high end bolt action out of a semi-auto. Someone at Palmetto really knows how to machine a barrel, set head spacing and match a bolt to it! This is one of the most accurate rifles I have ever owned! You'll see in the photo that I swapped out the A2 front sight for a flat top gas block and I replaced the standard round fore grip with a mid length Magpul MLok grip, but that is all the mods I did. It even has a standard Palmetto trigger in it, which I find to be totally adequate for a hunting rifle.
All Palmetto PA-10 in .308, a real Tack Driver!

Affordable, keep it clean.
I do recommend this.
Pros: Works great, accurate, cost efficient.
Cons: HEAVY
I only had one issue with this upper. That was after 2 days of shooting, then cleaning, the bolt started sticking. Couldn't chamber a round without really forcing it. After the first round, it fired just fine. Lots and LOTS of oil later, chambers and fires fine again. My guess is you have to keep this sucker really clean to maintain operation.

Happy AR-10 owner.....
Had a chance to play around with this upper the last two weekends. Shot some leftover 150 grain Remington factory ammo to put it on paper and then started to play around with some of my 168 grain Nosler handloads. 42 grains of H4895 did the trick and it was shooting great at 100 yards (even with a low power 1-4 Athlon scope).

Is it a little "over gassed"....? Maybe a little, but it seems to function just fine and it's still "breaking in". Overall, this is a great buy for what your getting. I bought the upper and Magpul MOE lower separate and actually saved about $60...... go figure!

Item performed better then I anticipated, flawlessly! Rapid fire was awesome!
A precautionary pre-fire barrel cleaning, BCG breakdown and lube as well as lubricating Upper's internal contact surfaces allowed this item to cycle flawlessly! No FTF, no FTE, no hiccups, just awesome cycling performance!

I have not shot mine yet but it has a sharp edge just below the forward assist that I cut myself on. I paid for a standard upper not a blemished one. My email to customer service was ignored
