Geissele Super Semi-Automatic Enhanced Trigger | SSA-E

The Geissele Super Semi-Automatic Enhanced (SSA-E) Trigger is a two-stage trigger designed for AR-15 and AR-10 platforms, offering a refined pull profile for improved control and consistency. Its two-stage design features a smooth first stage followed by a lighter, defined second stage break, supporting precise trigger operation across a variety of shooting applications.

This trigger utilizes a traditional curved (M4-style) trigger bow and is built for compatibility with standard mil-spec lower receivers. The SSA-E is a non-adjustable, semi-automatic trigger commonly selected for users seeking a lighter pull weight and predictable break characteristics. It is not compatible with Sig MPX, MCX, or pistol caliber carbine AR variants.
