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

Geissele triggers are trusted by professionals around the world, from special operations forces to competitive shooters. The reason is simple: uncompromising quality, precision manufacturing, and reliability. Each trigger is designed to perform in demanding conditions where smooth operation and consistent shot-to-shot performance are essential.

Geissele SD-3G is a competition-grade trigger designed specifically for dynamic shooting disciplines such as 3-Gun. It is a version of the S3G trigger featuring a flat trigger bow, further enhancing ergonomics and providing a lighter perceived trigger pull.

Features:

• Hybrid Rolling Break: A unique combination of single-stage and two-stage trigger characteristics. It offers short trigger travel and a smooth, rolling break without a distinct wall before the shot.

• Flat Bow: Provides improved leverage and tactile feedback, facilitating very fast and consistent follow-up shots.

• Lightning-fast reset: An exceptionally short and fast reset minimizes the time between shots.

• Safety and durability: Despite its competition-oriented characteristics, the trigger retains the robust construction and safety features associated with Geissele combat-grade designs.

Recommendations and notes:

The SD-3G features very short trigger travel and a light, fast reset. The manufacturer does not recommend it for duty use, precision shooting from a bench rest, or applications focused on maximizing group size. It is a specialized trigger designed for fast shooting at short distances.

Note: The trigger is not compatible with Sig Sauer MPX/MCX platforms or AR-15/M4 Pistol Caliber Carbine (PCC) variants.
