Geissele Super Dynamic Enhanced (SD-E) 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. Every trigger is designed to perform in demanding conditions where smooth operation and consistent shot-to-shot performance are essential.

Geissele SD-E is a two-stage trigger and a variant of the SSA-E model featuring a flat trigger bow. It was designed to deliver exceptional precision and excellent firearm control, combining the characteristics of combat-oriented triggers with the refined performance required for precision shooting.

Features:

• Flat Bow: Provides improved leverage and makes consistent finger placement easier, resulting in a lighter perceived pull and enhanced precision.

• Trigger characteristics: A smooth first stage followed by an exceptionally crisp, glass-like second-stage break, often compared to a candy cane-like break.

• Precision: Well suited to Designated Marksman Rifles (DMRs) and applications where maximum accuracy is required while retaining the reliability of a combat-proven trigger design.

• Construction: Based on technical solutions proven in demanding operational environments, optimized for a lighter trigger pull.
