Geissele Automatics S3G Super 3 Gun Trigger
Built for Maximum Speed. Trusted by Competitive Shooters.
The Geissele Automatics Super 3 Gun (S3G) Trigger is purpose-built for shooters who demand the fastest possible trigger reset and split times. Designed around Geissele's innovative Hybrid Rolling Break, the S3G blends characteristics of both single-stage and two-stage triggers to create an exceptionally smooth, lightning-fast trigger pull.
Unlike traditional triggers with a defined wall, the S3G offers a short, rolling break and an incredibly positive reset, allowing competitors to transition between targets and fire rapid follow-up shots with confidence. The curved M4-style trigger bow provides a familiar feel while maintaining precise finger placement during high-speed shooting.
Whether you're competing in 3-Gun, USPSA Rifle, Multi-Gun, or building the ultimate competition AR, the S3G is engineered to deliver unmatched speed without sacrificing Geissele's legendary reliability.
Note: The S3G is designed specifically for competition shooting and is not recommended for duty rifles, precision shooting, or benchrest applications due to its extremely short pull and rapid reset.
