Geissele Super Semi-Automatic Enhanced (SSA-E) Trigger
Built on the chassis of the Geissele SSA, the SSA-E has reduced first- and second-stage weights, giving a smooth, light take-up and a crisp, clean second-stage break. It is a semi-automatic-only version of Geissele’s two-stage combat trigger.
It suits precision and designated-marksman type rifles where accuracy matters and a robust, non-adjustable drop-in trigger is wanted.
- Two-stage, non-adjustable, reduced pull weights (approx. 2.9-3.8 lb total)
- Light first-stage take-up, crisp second-stage break
- Classic M4-style curved trigger bow
- Built on the SSA chassis
Designed for mil-spec AR-15/M4-pattern rifles. Not compatible with SIG MCX/MPX rifles or pistol-calibre AR-15 variants (fitting it to these voids the Geissele warranty). The same pull with a flat bow is the SD-E; with the semi-curved Lightning Bow, the SSA-E X.
