This G2S-E Trigger from Geissele Automatics is a match-grade, two-stage drop-in trigger for the AR-15. The trigger releases the hammer to fire the round, and a two-stage design gives a distinct take-up stage followed by a crisp break, which many shooters prefer for a predictable, repeatable feel over a single-stage trigger (Geissele Automatics part no. 05-276).

Key Specifications
