Geissele Automatics SDC Super Dynamic Combat 2-Stage Trigger
Built for Duty. Refined for Performance.
The Geissele Automatics Super Dynamic Combat (SD-C) is the flat-faced version of the legendary SSA (Super Semi-Automatic) trigger, delivering the same combat-proven reliability with the enhanced ergonomics and consistent finger placement of a flat trigger shoe.
Designed for duty rifles, defensive carbines, and general-purpose AR-15s, the SD-C provides a smooth first stage followed by a crisp, predictable second-stage break. The result is faster, more accurate shooting without compromising the rugged durability required for hard use.
Whether you're building a home defense rifle, patrol carbine, or premium all-purpose AR, the SD-C offers the perfect balance of precision, reliability, and control.
