yup, the gun is made from scratch by me.
The whole structure is made from some kind of hybrid between wood and paper, dont know the proper name for it (fibreboard?). and 1mm thick paper around the edges. + some custom parts. Whole thing is covered in layers of putty and white color and some lacker. The electronics are mostly made according some guides i found on internet, its an amplifier connected to a MP3 player and an old laptop battery.
