The amount of hot glue and bad soldering that I found inside this thing was insane! Whoever touched it last had zero idea wtf they were doing!
In the end I was able to fix it all and get a fully working lightgun shotgun for $20 plus parts, which were maybe fifty cents. Saved well over $100 compared to buying something tested working.
tutorial is useful to pretty much all light guns in part as well, since they are so similarly designed across all makers. Not identical but a lot of the hardware and concepts are the same
