3 Gun Shooters are a breed apart. They expect exceptionally accurate performance from their firearms, and they need it to be super-fast. When you want to introduce a trigger to your build that is lightning-fast and offers construction you can rely on look no further than the Geissele Super Dynamic 3 Gun Trigger. 

The Geissele Super Dynamic 3 Gun Trigger features a straight, consistent trigger pull designed for the way a 3 Gun shooter operates. This trigger features an extra short trigger pull, and a short reset allowing for extremely quick repeat shots on target. The straight trigger bow and single stage trigger pull create an even pull sensation, smooth as glass. 

The Geissele 3 Gun Trigger moves at 4 pounds and pulls through a short distance before firing. The trigger's weight doesn’t “load-up”, or “stack” as it approaches discharge, there is no friction during the pull and no feeling of “break” on firing. The trigger moves through a short overtravel and resets as soon as the shooter begins to relax his finger. There is no need to begin at the front end of the trigger pull again, the weapon is ready to fire when you are.

Geissele’s SD-3G is designed for high-volume, accurate shooting. Geissele is confident enough in their work to boast that shooters using rifles equipped with this trigger are able to aim and fire at their targets with more speed and accuracy than those using any other build combination available. Field tests prove the Geissele 3 Gun Trigger is consistently capable of delivering 12 shots accurately to target in a mind-blowing 1.6-1.9 seconds. 

The craftsmen of Geissele Automatics are competition shooters and firearm builders as well as precision weapon system designers. They know what it takes to perform in competition, and they provide components that you can be confident in every time you shoot.
