You asked, we listened! Palmetto State Armory is proud to release our Gen3 PA65 Barreled Upper Receiver!  The Gen3 model has been enhanced to improve the reliability and longevity of our PA65 platform. This new platform includes several features that have never before been included in our PA65 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 PA65 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 PA65 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, 6.5 Creedmoor 1/8 twist, rifle-length gas system barrel is paired with a Palmetto State Armory 15" Partial Picatinny Lightweight 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: Toolcraft 6.5 Creedmoor BCG is designed with double ejectors in order to ensure flawless cycling.  9310 steel bolt assembly, nitride treated for durability.  8620 carrier, with a nitride treated gas key properly staked with grade 8 fasteners.  Charging handle is also included. 

The Gen3 PA65 upper receivers are functionally and aesthetically compatible with Gen2 PA-10 Lower receivers.  However, 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.

Is the barrel nitride treated?
John B on Sep 18, 2019
BEST ANSWER: Barrel is stainless steel
The disclaimer says only cosmetic differences with Gen2 lowers, are there any photo examples to see just how different the generations are? Or what do you see as different?
Patrick M on Sep 29, 2019
BEST ANSWER: Enter aI paired this upper with a Gen 2 lower. The differences are only noticeable in two places where the upper and lower meet. You can see that the lines of the upper don't run as smooth into the lower, but I had to really look for it to notice. There is nothing about the fitment that would make me reconsider pairing the two.n answer to this question.
Is this compatible with the PSA Gen3 PA10 Lower?
Christopher S on Sep 23, 2019

Yes, it is.
