PICTURED LIGHTGUN IS NOT INCLUDED AND SHOWN ONLY FOR ILLUSTRATION OF INSTALLATION After purchase contact me and I will send the installation guide if you need it. This is a press-fit bracket I designed to replace the push buttons of the Sega Dreamcast Interact Starfire lightgun with microswitches behind the triggers. Requires a little soldering know-how. You may need to secure the bracket with a dot of hot glue but it is designed to be snug. Screws and brand new microswitches, 50 gram actuation force, are included with this kit. As this is a DIY alteration, it is the buyer’s responsibility to know what they’re doing. I can provide help by messages if you have any questions. Currently I am manufacturing with black plastic, but that may change to a different color if I run out. Note that there could be some dimensional variance in the injection molded parts that the 3D printed parts fit into. You may have to perform some filing or use a razor/sharp knife to widen holes if things are too tight. I design these kits to be snug as it’s better to have excess material instead of ‘not enough.’ These are custom designed pieces that will let you mount microswitches behind the triggers. When you disable the original button or desolder it out to replace it with this kit, you get a very precise action on the trigger. Accurate shots and no missed pulls. You just run wire from the common and normally-open tabs of the new switch to where the original button was. I also have microswitch kits available for a variety of different video game lightguns ranging from Sega, Nintendo and Sony! I will combine shipping!
