With streamlined styling and improved function, the new and improved PSA PA10 is here.  The Gen2 model offers an enhanced chamber and extraction, with a more modern appearance.

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.

Lower Build Kit: PSA PA10 ACS-L lower build kit with PSA Overmolded A2 Grip.  Everything you need to turn your PSA PA10 stripped lower into a complete lower.

  • 7075-T6 Forged aluminum receiver
  • 18" 416R Stainless Steel barrel
  • .308 WIN Chamber
  • 1 in 10 twist rate
  • Mid-length Gas system
  • PSA 15" Lightweight M-Lok Free Float Rail
  • A2-style muzzle device
  • 5/8-24 muzzle thread
  • Nitride BCG & Charging handle

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.

Good rifle kit great price!
I just built my second gen 2 and it shoots beautifully I love the rifle. The only issue I have with this build is there is a small gap where the back of the upper receiver meets lower it is not a tight fit on both of my gen 2 308’s

Bought this package and a stripped PA10 lower. Went ahead and got a H2 buffer as well. Topped it with a vortex Diamondback Tactical and Dropped in a Geissele SSA-E trigger. Got it out to the range shooting Federal Premium 150gr Trophy Bonded Tip and boy did it shoot. I shot 10 3 round groups and when I did my job it grouped sub MOA every time. My tightest group came in right under .5MOA. I wish I could add a picture for y'all but let me tell you it's a shooter. Can speak to the reliability since I only have 30 rounds down the tube but no malfunctions. I've heard people having trouble with pmags so I'm using a Lancer L7AWM Magazine. Better believe it's going into the woods with me on opening day of rifle season.
