The Geissele Automatics G2S (brand part number 05-145) is a non-adjustable, two-stage combat trigger built for AR-15 and AR-10 shooters who want precise, repeatable trigger control without an adjustable trigger’s extra fuss. Geissele machines it from the same tool steel as its higher-end SSA trigger, so the feel, reliability, and 4.25-4.75 pound draw weight carry over even though the G2S skips the SSA’s laser markings and full inspection in favor of spot magnetic-particle checks. It’s a drop-in upgrade finished in black oxide, built to hold up to duty and combat use.
