Manufacturer details
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 3 position adjustable gas block so you can specifically tune to your load.

This barrel is paired with a Palmetto State Armory 15" M-Lok free-float rail, low profile adjustable click detent 3 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.
