The Geissele Super Dynamic 3 Gun® (SD-3G®) trigger is the flat trigger bow version of the Geissele Super 3 Gun® (S3G®) trigger. Like the S3G, the SD-3G features a shortened pull length and lightning-quick reset, delivering a hybrid trigger pull that bridges traditional two-stage and single-stage characteristics while maintaining the safety and robustness of a two-stage combat trigger. The flat trigger bow reduces perceived pull weight and enhances tactile feedback, making it well-suited for 3 Gun competition shooting.
This non-adjustable trigger delivers a pull weight of 3.0 to 4.0 lbs with the lighter spring or 4.5 to 5.5 lbs with the heavier spring. The SD-3G is engineered with a very short, light pull and reset for close course competition use where rapid target engagement and quick follow-up shots are essential. The trigger is designed for mil-spec AR15/M4 carbine rifles.
Each trigger ships with clear directions, a trigger pin slave, and grease. The machining is executed to a high standard with no sharp edges or burrs, and the face is smooth almost to a polish. This drop-in replacement transforms your AR platform rifle for competition shooting performance.
