The Geissele SD-E Super Dynamic Enhanced Trigger (05-167) is a finely-tuned semi-automatic-only version of our full-auto, two-stage combat trigger presently used in the U.S. Special Operations Community. Built on the chassis of the Geissele SSA, the SD-E provides enhanced trigger control and weapon accuracy while maintaining the robustness and reliability of our combat-proven two-stage trigger. The SD-E’s reduced 1st and 2nd stage pull weights result in a trigger with a smooth, light 1st stage take-up and a crisp, candy cane-like 2nd stage break. The SD-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.
- 1st: 2.2-2.5 lb
