You asked, we listened! Palmetto State Armory is proud to release our Gen3 PA10 Barreled Upper Receiver!  The Gen3 model has been enhanced to improve the reliability and longevity of our PA10 platform. This new platform includes several features that have never before been included on our PA-10 platform. We hope you enjoy these new features and look forward to your feedback!

With enhanced durability and improved function, the new and improved PSA PA10 Gen3 is here.  The Gen3 model offers a black nitride stainless gas tube to better resist high heat and corrosion while maintaining a glossy black finish.  All Gen3 PA10 models come with a dimpled barrel for ease of gas block replacement if you choose to do so. We have also included a newly designed click switch 5 position adjustable gas block so you can specifically tune to your load.

Gen 3 Benefits at a glance:

  • Dimpled 416R Stainless Steel Barrel
  • 5 Position Adjustable Click Switch Gas Block
  • Extra Power Extractor Springs
  • 7075 T6 Charging Handle Included in all uppers
  • Black Nitride Gas Tube
  • Barrel Nuts properly torqued to military specifications
  • Anti-slip and anti-rotation handguards

 

Barrel: The dimpled, 416R Stainless Steel, 308 WIN 1/10 twist, mid-length gas system upper is paired with a Palmetto State Armory 15" M-Lok free-float rail, low profile adjustable click detent 5 position gas block, and an A2-style muzzle device. The gas system is enhanced with a nitrided gas tube in order to better resist high heat and corrosion.

Upper:  Precision machined from forged 7075-T6 aluminum, then Black anodize hard coated to MIL-8625 Type 3 class 2. With enhanced dual retention anti-slip and anti-rotating handguards.  

Bolt Carrier Group: Tool craft 9310 steel bolt assembly with extra strength extractor springs that is nitride for increased durability.  8620 carrier, nitride treated, with a nitride treated gas key properly staked with grade 8 fasteners.  A 7075 T6 aluminum charging handle is also included.

The Gen3 PA10 receivers are functionally compatible with the Gen1 and Gen2 upper receivers, however, we recommend matching Gen3 lowers to Gen3 uppers for best appearance and performance.  There are external cosmetic differences when mixing Gen1 with Gen2 and Gen3 upper and lower receivers that some may not find appealing.  

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.

How well does the Gen 3 upper fit on the Gen 2 lower?
Jesse N on Aug 7, 2019
BEST ANSWER: Fits perfectly...
You guys didn’t listen hard enough. I want non stainless steel barrels?
Zach E on Aug 9, 2019
BEST ANSWER: Why are you so hard up about the stainless steel barrels?
When can we expect 20 inch upper receivers to become available?
Thompson B on Aug 8, 2019
Are Gen 2 uppers still going to be available? is the Receiver the same and just the gas block and such different on the Gen 3?
M in N TX on Aug 8, 2019
BEST ANSWER: really.....??? With the improvements of the G3 over the G2 (I own one of these) 'why' would PSA continue to produce G2's?? It only makes sense that once the G2's are gone, we will have 'collectibles'.... The G3 lower receiver has a different 'cut' at the rear. Look closely at the photo where the buffer tube attaches. You will see a Triangle cut. The guys at the Greenville store told me this new cut is to allow the G3 to accept more and different BCG's. I'll take them at their word.
What is the standard weight of this ar10?

What is the weight of the "heavy buffer" ??
William D on Aug 8, 2019
BEST ANSWER: "Or" just do a little bit of research on your own to get a real answer....
I have ordered my Gen 3 lower, but I really want to set my AR10 up with a 20 or 22 inch barrel. I want to get the most that I can from a 308 platform, and I would like to build a designated longer range rifle for my modern arms line up. When can we expect extended barrel lengths. Happy to see that the lower is marked MULTI, so if for some odd reason I ever wanted to go pistol length I could be legit. THE QUESTION IS, ( W H E N ? )
the Mole on Aug 9, 2019
BEST ANSWER: once you build it as a rifle you cannot then make it into a handgun without a visit from the batf. You can build it as a handgun and then switch it to a rifle but technicaly once its a rifle it has to stay that way.
Does the gen 3 solve the problem of your upper receivers being in between a high and low dpms so we are not stuck with PSA's handguard?
Joel K on Aug 12, 2019
BEST ANSWER: hummmm.... "I" rather like the hand guard on my G2 PA-10... rails in the front and back and dropped in the center w/o a rail for those us us with girl (size) hands....
Is the ar 10, 18inch (complete) upper Dpms compatible ? Or more specifically does it follow the Dpms version of AR10’s?
Coolcamero on Aug 24, 2019
BEST ANSWER: "MY" understanding is that PSA and DPMS both use the same template/pattern for their weapons....

Anyone know how this will fit with an Aero M5 lower?
mitchell s on Sep 2, 2019
BEST ANSWER: PSA only guarantees it will fit PSA lowers.... That said, the G2's will accept DPMS, and DPMS patterned lowers, as I understand currently....

A 4 Star Before Shooting
I have a virgin Gen2 lower. It was a fight to get this upper inserted into the lower for the front pivot pin. Not sure which piece is causing it. Just an observation, not a criticism.

What I would like to see is instructions for the adjustable gas block. Which way do I turn it to add more gas? Are we supposed to guess? Why not include a tool to adjust it?

I have not fired this yet, hence the 4 star rating.

Exceeds expectations
Finally received this today along with the complete lower. Added a few minor mods like an odin atlas 7 comp, different charging handle, ergo grip, side mount bipod, extended mag release and put an M-tactical 308 nikon on it. Sighted at 100 and was popping 5x5 steels at 500 yards consistently. Put a paper up at 300y and the only group of 3 shots I took at it were at 1moa a Triangle of 2"x2"x3" very pleased so far with the combo and as it was my first 20 rounds through the rifle i know it can do better.

Looks Amazing, quality build, great fitment
I just received this upper today, so this is just a "what I see" review. The lower i ordered has not shipped out to my FFL yet, so I can't comment on function or accuracy of this upper.
What I can share is that this is one really good looking upper. The machining is of high quality and the colors (black) match perfectly. The barrel looks real nice too, with a high sheen SS finish and mirror like looking feed ramps. The BCG is as smooth and buttery looking as I've ever seen. So overall, the first impression of this upper is super nice quality at an amazing price.
I plan on changing the brake, which is the only weak link on this upper, IMO. Once my lower is in at my FFL and I've waited the 3 days to pick it up,(after filling out and waiting on approval on my 4473, of course) I'm really excited to see how this package performs. If the rifle functions well I'm able shoot sub 2 MOA out of it, I'll be really happy. I bought this to shoot out to 600 yards at paper and steel targets at my club.
I don't expect F Class precision from it, but with the improvements on the Gen 3 version, I'm hoping the rifle will be enjoyable to shoot. 4 Star quality at 2 star prices. Thanks PSA. I'll update this review once I've put some rounds down range.
