up through bottom of trigger
slide.
Install the slide into the tapered
slot of the trigger base. Push a
small rubberband through the
rectangular window of the slide.
Loop the rubber band over the
notched fingers of the base.
Screw an M3x50mm machine screw
down the center hole of the sled.
Capture it out the back with an M3 jam
nut which should sit flush within the
circular boss recess. Tighten.
Install an M3 Nyloc nut onto the end

the top of the pylon and pull it tight to secure it.
Connect the trigger and launcher assemblies with
2 sections of track. The grooves in the track go
toward the outside and should line up with the
grooves in the launcher assembly.
