Geissele Super Dynamic 3 Gun® (SD-3G®) Trigger

Super Dynamic 3 Gun® (SD-3G®) Trigger

The Geissele Super Dynamic 3 Gun® (SD-3G®) Trigger is a high-performance trigger designed for AR15 / AR10 platforms, with a strong focus on dynamic sport shooting and 3 Gun competition. It is the flat trigger bow version of the Super 3 Gun® (S3G®) trigger, offering an extremely short pull, lightning-fast reset and outstanding speed for rapid follow-up shots.

The SD-3G® features a unique Hybrid Rolling Break trigger feel, combining characteristics of both traditional two-stage and single-stage triggers. This provides a fast, smooth and highly responsive trigger pull while maintaining the safety and robustness expected from a proven Geissele trigger system.

The flat trigger bow enhances trigger control, improves tactile feedback and helps reduce the perceived pull weight. The SD-3G® is an excellent choice for competitive shooters who require speed, consistency and a very short reset in close-course competition environments.
