The new and improved Palmetto State Armory PA10 Gen3 .308 lower is fully assembled and ready for your complete PA10 Gen3 Upper!

Based on customer feedback we are pleased to announce the Gen 3 PA-10 Complete Lower Receiver! Using forged 7075-T6 aluminum, these lowers are precision machined and then black anodize hard coated to MIL-8625 Type 3 Class 2 specifications.  This complete lower will include a popular EPT fire control group with A Magpul MOE Stock and PSA Overmolded Pistol Grip. The PSA PA10 allows the same configuration flexibility as enjoyed by the AR15 and is an ideal platform for the .308 cartridge. 

Gen 3 enhancements at a glance:

  • Lower includes relief cuts for a broader compatibility with .308 BCG’s.
  • Twice staked castle nuts
  • Standardized carbine length buffer tube with short, heavy buffer


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.

Love it, but can’t use pmags.
I bought this lower for my 16 inch bear creek upper. Fit is perfect and shot 7 different brands of ammo; steel and brass and different bullet weights. Everything worked perfectly. My only issue is that pmags do not lock in the magazine well. I tried the 10 and 25 round magazines. Neither would lock into place, even after a hard slap. I ended up purchasing the asc metal magazines and they work fine. They are a bit loose but they eject nicely. Overall I like the fit and finish and would recommend it as long as you are ok with the metal magazines.
