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 Mil-Spec AR15 fire control group with PSA Classic stock and 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.

If the Gen 3 is designed for use with a broad compatibility of 308 BCG's why does PSA recommend using their products only?

Does my PSA AR-10 gen-3 trigger assembly have small or large pins?
Jesse H on Sep 6, 2019
BEST ANSWER: The description states: " Mil-Spec AR15 fire control group". Small or large pins are a question for some rather old Colt AR receivers sold during the failed Bush the gun banner presidency. You are 30 years out of date.
has the magazine issue been fixed ?

Gen 3 Pmag issue also
After reading the other review i tried some Gen. 3 mags also. i had the same issue at first. The release will only hold my gen 3 mags if you slap the bottom of the mag very hard. Otherwise they will fall out.

Pmags don't fit
The molded angle of the magazine on the gen 3 window magpul pmag will not allow the mag release to hold magazines in place allowing it to fall out...first I attempted to resolve problem by tightening and loosening mag release but did not work... after smackin the mag a few times I could see that the mag was not seating because it was hitting the receiver... lower looks great and for the price I'll just have to get different mags

Magazine catch fails to retain Gen 3 pmags.
This is a sample size of one, so keep that in mind. I just picked my lower up from my FFL and bought a 25 round Gen 3 pmag. The mag will not lock into the lower. The mag catch fails to retain the magazine and it can be simply pulled out after inserting it. It seems to be a defective lower as the Magpul pmag is the mag that PSA ships thier complete rifles with. I'm trying to get PSA's help in resolving this issue. At best it's a manufacturer defect and I end up paying another FFL transfer fee for another lower, so that kinda sucks.
