Geissele Super Dynamic 3 Gun (SD-3G) Trigger – AR-15/AR-10

The Geissele Super Dynamic 3 Gun trigger is a single-stage, flat-bow competition trigger designed for speed in 3-gun and multi-gun disciplines. It delivers a crisp, clean break optimized for rapid target transitions without sacrificing control. The flat trigger face provides consistent finger placement for repeatable performance across varied shooting positions.

Machined from tool steel with a precision-ground engagement surface, the SD-3G is a drop-in trigger assembly compatible with mil-spec lower receivers. Geissele's two-stage manufacturing process ensures consistent pull weight and minimal creep. Installation requires basic AR maintenance tools and familiarity with lower receiver assembly—no permanent modifications to the firearm.
