  • Manufacturer: Geissele
  • Model: G2S 2 Stage Trigger (05-145)



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 between the SSA and the feel and reliability are the same. The G2S, however, has a different way of holding the hammer pin in place, there are no laser markings, and the parts are only spot checked for MP.

    This trigger does not work with the pistol caliber setups, the bottom of the BCG sits too high to ride the hammer back to the disconnector. We recommend the ALG ACT trigger, it works very well in PC builds.
