Geissele Super 3 Gun (S3G) Trigger 05-152

Geissele Super 3 Gun (S3G) Trigger 05-152 bridges the gap between a single-stage trigger and the standard two-stage trigger for AR15 and AR10 platforms. It provides a short, light pull and a quick reset.

This Geissele S3G Trigger is a semi-automatic-only derivative of the two-stage Super Select-Fire combat trigger Geissele builds for U.S. Special Operations customers. That heritage carries over into the pull feel — match-grade semi-automatic performance combined with the smooth, single-stage character of the SSF's full-automatic mode. Total pull weight runs 3.0-4.0 lbs with the included lighter spring, or 4.5-5.5 lbs with the heavier one, giving shooters some control over feel without true adjustability.

Recommended for 3 Gun competition only, this trigger isn't built for duty use, bench rest, or precision accuracy work. It's designed specifically for close-course competition, where rapid target engagement matters more than an ultra-refined break. As always, it's not for use with Sig Sauer MPX/MCX weapons or pistol caliber variations of the AR15/M4 — doing so voids the warranty.

Key Features:

• Hybrid rolling break, semi-automatic derivative of the SSF combat trigger
• Total pull weight: 3.0-4.0 lbs (light spring) or 4.5-5.5 lbs (heavy spring)

This Geissele trigger gives 3 Gun shooters a fast, robust option without sacrificing the reliability of a combat-proven design.
