Geissele SSA-E X Trigger with Lightning Bow
The SSA-E X uses the reduced pull weights of the Geissele SSA-E: a smooth, light first-stage take-up followed by a crisp second-stage break. It is aimed at precision and designated-marksman type rifles where accuracy matters but a robust, non-adjustable drop-in trigger is wanted.
The Lightning Bow is a semi-curved, wide-body trigger shoe that sits between the classic curved AR trigger and a flat bow.
- Two-stage, non-adjustable, reduced “Enhanced” pull weights (approx. 2.9-3.8 lb total)
- Smooth, light take-up and a crisp second-stage break
- Lightning Bow: semi-curved, wide-body trigger shoe
- Nanoweapon coating on the major components for wear and corrosion resistance; keeps running smoothly with minimal lubrication
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). For the heavier SSA pull weights with the same bow, see the SSA X.
