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 Geissele Super Semi-Automatic Enhanced (SSA-E) Trigger, a Magpul STR 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
Geissele SSA-E Trigger:
Built on the chassis of the Geissele SSA, the Super Semi-Automatic Enhanced (SSA-E) provides enhanced trigger control and weapon accuracy while maintaining the robustness and reliability of the combat-proven two-stage trigger. The SSA-E’s reduced first and second stage pull weights result in a trigger with a smooth, light first stage take-up and a crisp, candy cane-like second stage break.
It has a simple design similar to the original M16 trigger. There are no adjustment screws to come loose and all springs are captive, they will not get lost during disassembly. The entire trigger can be disassembled for cleaning and can be installed without removing the safety.
The SSA-E is ideal for use in precision Squad Designated Marksman type rifles where weapon accuracy and reliability are critical and a non-adjustable drop in trigger is desired.

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.
