MoNoRi-Chan's weapon of justice (or for his own vigilante)
It is a weapon that was introduced in later episodes of Gmod Idiot Box given to MoNoRi-Chan by Dr. Hax when he was retired. MoNoRi-Chan resized it to a handheld size and used it during his times as admin in various Garry's mod servers. While small but mighty and can bring rule breakers or cheater to a justice.
