Product Overview and Introduction

Experience uncompromising tactical performance and precision control with the Geissele Automatics Super Dynamic Combat (SD-C) Two-Stage Trigger featuring a match-grade Flat Bow and a robust 4.5 lb Total Pull Weight – MPN: 05-165. Engineered as the flat-bow equivalent to Geissele’s famous combat-proven SSA, the SD-C is built specifically for law enforcement, military operators, and civilian defenders who demand a reliable two-stage trigger with a distinct flat face for enhanced leverage.

Whether you are equipping a hard-use patrol rifle, a home-defense carbine, or a tactical precision build, the SD-C delivers a smooth first-stage take-up followed by a clean, predictable second-stage break that gives you absolute confidence under pressure.

Combat-Ready Two-Stage Engineering and Flat Bow Ergonomics

Engineered to exacting military specifications, the SD-C combines rugged durability with refined internal geometry:

• Robust Duty Pull Weight: Factory-tuned to a total pull weight of approximately 4.5 pounds (roughly 2.75 lb first stage and 1.75 lb second stage), providing an ideal safety margin for high-stress environments while remaining exceptionally crisp.

• Flat Match Bow Design: The flat trigger face provides a consistent, repeatable finger placement surface, allowing for a straight-back pull and enhanced leverage that makes the pull feel slightly lighter and more controlled.

• Controlled Second-Stage Break: Designed with a clean, predictable break that eliminates creep and helps you place accurate shots precisely where intended.

• Full-Power Hammer: Utilizes a robust, full-weight hammer to ensure 100% reliable primer ignition across all commercial, duty, and military-spec ammunition types without light strikes.

The Benchmark for Tactical Flat Triggers

Geissele’s Super Dynamic Combat trigger bridges the gap between match-grade precision and duty-grade reliability. It gives tactical shooters the ergonomic advantages of a flat trigger without sacrificing the safety margins and heavy-duty construction required for rigorous operational use.
