Geissele Automatics Super Semi-Automatic Trigger (SSA)

Geissele Automatics Super Semi-Automatic Trigger (SSA)

The Geissele Automatics Super Semi-Automatic Trigger, commonly known as the SSA, is a non-adjustable 4.5 lb two-stage combat trigger designed for precise control in demanding AR-platform applications. Based on Geissele’s Super Select-Fire trigger design, the SSA balances a predictable two-stage pull for accurate shots with the control and forgiveness needed for close-quarters and general-purpose carbine use.

Two-Stage Control for Precision and Practical Use

The SSA trigger uses a defined first stage followed by a clean second-stage break. This two-stage configuration helps shooters take up initial pressure deliberately before completing the shot, supporting controlled trigger operation for both close-range work and mid-range carbine applications.

Non-Adjustable 4.5 lb Combat Trigger

With a total pull weight of 4.5 lb, the SSA is built as a duty-oriented, non-adjustable trigger. Its fixed configuration eliminates the need for user pull-weight adjustments while providing the consistent operation expected from a quality combat-style trigger.

Designed for Demanding Applications

The Geissele SSA is recommended for law enforcement use, close-quarters battle applications, and mid-range carbine work. It is safety certified by Crane Naval Surface Warfare Center and is intended for shooters seeking a durable, reliable trigger with refined two-stage control.
