What Are the Specs of the SSA Trigger by Geissele Automatics?

Woody's answers are based on published federal and state law. Not legal advice. Consult a licensed attorney for your specific situation.

Quick Answer

The Geissele SSA is a two-stage semi-auto trigger for AR-15/AR-10 platforms with a 2.75-3.0 lb first stage, 1.5-1.75 lb second stage, and 4.25-4.75 lb total pull weight with positive reset.

How This Affects Your Build

The SSA represents Geissele's approach to a precision semi-automatic trigger that balances control with performance. This two-stage design gives you the tactical advantage of a deliberate first stage while maintaining the crisp break needed for accurate shooting. The weight distribution across both stages makes it suitable for both precision work and general purpose applications.

The Detail

The Geissele SSA uses a two-stage trigger mechanism that splits the pull weight across distinct phases of operation. The first stage requires 2.75 to 3.0 pounds of pressure, giving you a controlled take-up that helps with shot preparation and follow-through discipline.

The second stage breaks at 1.5 to 1.75 pounds, creating the final release that fires the rifle. This lighter second stage provides the crisp break you need for precision work while the heavier first stage prevents accidental discharge during rapid handling. The total pull weight ranges from 4.25 to 4.75 pounds when you combine both stages.

Geissele designs this trigger specifically for semi-automatic operation on both AR-15 and AR-10 platforms. The positive reset characteristic means you get clear tactile and audible feedback when the trigger resets after firing, allowing for faster follow-up shots without having to completely release the trigger.

The weight ranges Geissele publishes account for manufacturing tolerances and individual component variations. Your specific trigger will fall somewhere within these ranges, but the two-stage behavior and positive reset remain consistent across all units.

Build Impact

You're looking at a trigger that works equally well in precision and general purpose builds without requiring different shooting techniques. The 4.25-4.75 pound total weight keeps you in safe territory for most applications while the two-stage design gives you the control benefits of a match trigger.
