Geissele Super Dynamic Enhanced (SD-E) Trigger

Geissele Super Dynamic Enhanced (SD-E) Trigger

The SD-E has the same mechanism and reduced “Enhanced” pull weights as the Geissele SSA-E, but with Geissele’s flat trigger bow instead of the classic curved M4 shoe. It gives a light take-up and a crisp break while keeping the robustness of a two-stage combat trigger.

• Two-stage, non-adjustable, approx. 2.9-3.8 lb total pull
• Flat trigger bow
• Same pull weights as the curved-bow SSA-E
• 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). Colt 901 owners need Geissele’s wider-receiver pins (sold separately).
