The Geissele Super 3 Gun (S3G) trigger is a semi-automatic-only derivative of the two-stage Super Select-Fire (SSF) combat trigger that Geissele Automatics produces for customers in the U.S. Special Operations Community.

The S3G was developed to combine the SSF combat trigger’s match-grade semi-automatic performance with its smooth single-stage full-automatic feel to make a fast, smooth, and robust trigger ideal for 3 Gun competition shooting.

Fits Standard AR15s

Note: Will not fit "Large Pin" Colt rifles

Note: The S3G trigger has a very short, light pull and reset. Geissele does not recommend it for duty use, bench rest, accuracy work or shooting small groups. It is designed for close course competition use where rapid target engagement with quick follow up shots are required.

The Geissele Super 3 Gun (S3G) trigger is a semi-automatic-only derivative of the two-stage Super Select-Fire (SSF) combat trigger that Geissele Automatics produces for customers in the U.S. Special Operations Community.

The S3G was developed to combine the SSF combat trigger’s match-grade semi-automatic performance with its smooth single-stage full-automatic feel to make a fast, smooth, and robust trigger ideal for 3 Gun competition shooting. The new Geissele Super 3 Gun trigger has a super short trigger pull and a short reset so that rounds can be sent downrange as quickly as possible while still maintaining superb accuracy.

The SSF’s long, smooth pull was shortened and combined with a lightning-quick reset to give it a unique, hybrid trigger pull that is a cross between a traditional two-stage and single-stage trigger while at the same time retaining the safety and robustness of the SSF’s two-stage trigger design. The result is an outstanding, well-balanced trigger that is ideal for high-volume, accurate fire.

An S3G-equipped rifle enables the shooter to engage targets faster and more accurately than with any other trigger/rifle combination available today. Field tests have shown that expert S3G shooters can routinely and accurately deliver up to twelve shots on an IDPA target at 7 yards in an amazing 1.9 seconds.
 

1. The shooter starts pulling the trigger as his sights become aligned on target.
2. At about 3.5 lbs., the trigger starts to move back smoothly, like it’s on ball bearings.
3. After the trigger moves a short distance, the weapon discharges. Nothing precedes the discharge: no second stage stop, no grittiness, no stacking of the trigger pull weight as the hammer is cammed down like on a stock AR15 trigger. The trigger finger feels a sensation of walking along a perfectly flat, glassy-smooth plateau that suddenly drops away.
4. After a short overtravel, the trigger is quickly reset when the shooter slightly relaxes his trigger finger and the next shot is ready to be fired without having to go back to the beginning of the trigger pull cycle.
