Geissele Automatics SSA AR-15 2-Stage Curved 4.5 lb Trigger - Non-Adjustable

The Geissele Automatics Super Semi-Automatic (SSA) is a precision 2-stage, non-adjustable combat trigger designed for the AR-15/M16 platform. Built around a curved trigger bow and timed to a factory specification, the SSA delivers a smooth first-stage pull, clean break, and short positive reset that make it a popular upgrade for precision AR builds and duty carbines.

Machined from steel and assembled in the USA, the SSA drops into a standard AR lower receiver using Mil-Spec .154" trigger pins, with no adjustment screws or springs to set. Its 2.75 - 3.0 lb first stage transitions into a crisp 1.5 - 1.75 lb second stage, for a total pull weight of 4.25 - 4.75 lbs across the full stroke.

Unlike adjustable designs, every SSA is factory-tuned to the same specification, so the feel is consistent from trigger to trigger. This repeatability, combined with the SSA's short reset, helps the shooter stay on target during rapid follow-up shots and makes the SSA equally at home on a competition rifle, a duty carbine, or a precision AR build.
