The Geissele 2 Stage (G2S) was designed to be a high-quality, cost-effective option of the SSA. The G2S is a 4.5lb. 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.
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.
