Product Overview and Introduction

Experience the ultimate combination of flat-bow ergonomics and legendary match-grade precision with the Geissele Automatics Super Dynamic Enhanced (SD-E) Two-Stage Trigger featuring a match-grade Flat Bow and a light 3.5 lb Total Pull Weight – MPN: 05-167. Engineered as the flat-bow counterpart to Geissele’s world-renowned SSA-E, the SD-E is designed for precision marksmen, competitive shooters, and enthusiasts who demand an exceptionally crisp, glass-rod break combined with the straight-pull advantages of a flat trigger face.

Whether you are building a dedicated long-range precision gas gun, a DMR, or a high-end competition rifle, the SD-E delivers a smooth, feather-light two-stage pull that dramatically tightens your shot groups at distance.

Precision Match Engineering and Flat Bow Ergonomics

Engineered to exacting tolerances, the SD-E merges exquisite trigger control with comfort and reliability:

• Ultra-Light Precision Pull: Factory-tuned to a smooth total pull weight of approximately 3.5 pounds (roughly 2.3 lb first stage and 1.2 lb second stage), offering minimal resistance and zero perceptible creep.

• 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 trigger feel even lighter and more controllable.

• Glass-Rod Second-Stage Break: Designed with an ultra-clean, unmistakable break that lets you precisely predict the moment of ignition for superior accuracy.

• Positive Tactical Reset: Features an exceptionally short, distinct reset for rapid, controlled follow-up shots under pressure.

• Full-Power Hammer: Utilizes a robust hammer and reliable spring geometry to ensure positive ignition across all commercial, match, and military-spec ammunition types without light strikes.

The Pinnacle of Flat-Bow Precision

Geissele’s Super Dynamic Enhanced trigger is trusted by top-tier shooters who want the mechanical advantages of a flat trigger face paired with the benchmark performance of the SSA-E. It gives you the confidence to make every precision shot count.
