This is a Geissele Automatics Trigger known as the Super Semi-Automatic, model 05-160.
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 our 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. 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.
