Fusion Engine Speed Trigger Modification

The Fusion Engine can be easily modified so you can make the trigger throw adjustable and create a “speed trigger” setup. There are many variations for implementing a speed trigger, but I prefer using a setscrew so it is possible to adjust the trigger throw.

The setscrew can be used to bring the trigger closer to the microswitch which would reduce the trigger pull throw. To retain the Safe function, the safety lever will need to be trimmed/filed down so it will block the trigger just before it hits the microswitch.

Happy Airsofting!
