Super Semi-Automatic Enhanced (SSA-E) Trigger Description

Built on the chassis of the Geissele SSA, the Super Semi-Automatic Enhanced (SSA-E) provides enhanced trigger control and weapon accuracy while maintaining the robustness and reliability of Geissele's combat-proven two-stage trigger. The SSA-E’s reduced first and second stage pull weights result in a trigger with a smooth, light first stage take-up and a crisp, candy cane-like second stage break. The SSA-E is ideal for use in precision Squad Designated Marksman type rifles where weapon accuracy and reliability are critical and a non-adjustable drop in trigger is desired.

The Geissele Super Semi-Automatic Enhanced (SSA-E) Trigger is a finely-tuned semi-automatic-only version of Geissele's full-auto, two stage combat trigger presently used in the U.S. Special Operations Community.

For a flat bow version of this trigger please see the Super Dynamic Enhanced (SD-E) trigger.

    Outstanding Trigger

    I installed this trigger on an otherwise unmodified Ruger SR556. What an improvement! Smooth, crisp, and consistent from the very first round. One of the very best triggers I have ever used.

    Next upgrade will be to the full auto trigger.

    Best Combat triggers on the market

    Geissele Automatics has a winner here. If you have ever had the chance to shoot an SSA unit, I'm sure you were impressed. This is an SSA "turned up to ELEVEN". Break is lighter, crisper, and comes after less travel. Reset is even shorter than the SSA, which is already very abbreviated.

    Simply outstanding. All components are individually serialized and MPI'd. Yes, you read that right. I don't know of any other trigger manufacturer who is this anal with QC.

    It is battle ready and still runs with any precision trigger unit. It's designed for a lifetime of hard use.

    SSA-E Review

    I have 3 diff't trigger packs, factory Stag, Rock River NM2, and this unit. Out of all three, the Geissele is my favorite, short first stage, and the second stage is near perfect for me. It may not be the cheapest piece you can find, but the performance and simplicity of it are tough to beat.

    My first 2 stage trigger

    after countless hours reading up on triggers for a "SPR" I decided on this one. I needed something grunt proof with no tiny adjustable part to loose or break. I wanted something easy to put in, light, crisp and that would set off my ammo reliably. Finally I wanted it to be affordable it was priced right around the middle of the pack as far as match grade 2 stage triggers go. I'm very Pleased with the SSA-E and it has exceed my expectations.
