The Geissele 2 Stage (G2S) was designed to be a high
quality, cost effective option of the Super Semi-Automatic (SSA®) trigger.
The G2S is a non-adjustable combat trigger that is a
precision two-stage trigger and allows precise and accurate trigger control.
The G2S is manufactured from the same tool steel as the SSA and the sears are
also wire EDM cut. Visually, from the outside of the weapon there is no
difference from the SSA and the feel and reliability is the same. The G2S
however has a different way of holding the hammer pin in place, there is no
laser markings, and the parts are only spot checked for MP.
