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. Features: Type: 2 Stage 1st Stage Weight: 2.3lbs 2nd Stage Weight: 1.2lbs Total Pull Weight: 3.5lbs Adjustable: No Size: Mil-Spec Trigger Bow Type: M4 Curved Weapon Platform: AR15/AR10
