Geissele SSA X Trigger with Lightning Bow
The SSA X carries over the pull weights of Geissele’s Super Semi-Automatic (SSA), the duty-rated two-stage trigger that is light enough for precise shots but forgiving enough for fast close-range work. Its Lightning Bow is a semi-curved, wide-body shoe that sits between the classic curved AR trigger and a flat bow.
- Two-stage, non-adjustable, SSA pull weights (approx. 4.5 lb total)
- 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
- Drop-in for AR-15 and AR-10 lower receivers with mil-spec pins
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).
