Installing an Ammo Counter
This is a small walk through of installing one of my ammo counters.
Power up and overview
Your ammo counter is ready to power on out of the box. Just insert batteries, then find the switch on the battery box.
If your kit came with a lever switch, press it and you will see the count change. For the optical sensor, aim the two beam sensors at each other and break the IR beam.
- Change ammo clips: Click left or right to cycle between the clips.
- Change ammo count: Hold right button until the display is flashing, then click left/right to change the ammo. Press and hold right to save the setting.
Install
Your kit came with all the wires pre-soldered. However, it is still recommended that you cut the wires and re-solder to adjust the wire lengths to match your build.
Lever switch
To install the lever switch, open your blaster and examine the trigger and action assemblies. You are looking for a spot where there is a moving piece that can push into the lever switch with each shot fired.
The lever on the lever switch is quite long to support a variety of builds. You can trim the lever shorter to fit your install by bending it back and forth several times with a needle nose pliers.
