Geissele Automatics 05-171 Super Semi-Automatic Enhanced (SSA-E) - Large Pin

Finely-tuned semi-automatic-only version of the full-auto, two stage combat trigger presently used in the U.S. Special Operations Community. The large pin dimension is 0.169 inches, whereas the standard pin dimension is 0.155 inches. 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 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. Please note, these triggers are designed for mil-spec AR15/M4 carbine rifles. The AR15 triggers are not compatible with the Sig MPX/MCX weapons or Pistol Caliber Carbine AR15/M4 variants. Using them in these platforms will void the warranty. Large pin version of the Geissele Super Semi-Automatic Enhanced (SSA-E) Trigger for use in Colt AR rifles manufactured from 1990 to 2009.
