Geissele SSA E – Geissele Automatics Super Semi-Automatic Enhanced SSA-E Two-Stage AR-15 Trigger (.154)

The Geissele SSA-E (Super Semi-Automatic Enhanced) is a two-stage, drop-in AR-15 trigger built for shooters who want a lighter, cleaner break than a standard mil-spec unit. As a refined match trigger, the Geissele SSA-E pairs a smooth take-up first stage with a crisp, predictable second-stage break for precise, repeatable shot placement.

This is an ordinary semi-automatic trigger that fires one round per trigger pull. Always follow your state and local laws before purchasing. You must be of legal age and eligible under federal, state, and local law to purchase.

Specifications and fitment

Why shooters choose the SSA-E

The two-stage design lets you take up the first stage while settling on target, then break the shot with a light, glass-like second stage. It sits among the best forced reset triggers and match-grade options shooters reach for when accuracy matters. Because the trigger is non-adjustable, every unit performs the same out of the box, with no fine-tuning required. That consistency makes it a popular choice for precision rifles, designated-marksman builds, competition, and duty use.

Drop-in installation

The SSA-E installs like a standard AR-15 trigger group using .154-inch pins, so it drops into most AR-15 and AR-10 lowers without modification. Basic hand tools and a few minutes are all that is typically needed. If you are still comparing options across our range of AR-15 triggers, the SSA-E is an easy, no-gunsmithing upgrade.
