http://www.youtube.com/watch?v=Sf3M-_RUSCM&feature=channel_page The problem is I don't know what brand of laser this guy uses! I saw other vids that claim it can be done on a Radio Shack laser, but the problem is the Radio Shack brand doesn't have a screw that tightens (which would mean maximum power output has been set). Has anyone ever done a laser mod, or is familiar with it? I want a laser gun so I can run around town screaming "IM CHARGIN MAH LAZER!!! SHOOP-DA-WOOP!!!"
