Ever since I got this awesome tiny USB light I wanted to mount it on a rail! I hope you enjoy! Post a make with it on your gun! Perfect for airsoft, especially if you don't want to buy a fancy tactical light (which eats your expensive or difficult to charge batteries) or want something slim and light!

Use a M3x30-32mm screw and nut to attach! You may have some of these parts already if you own a 3D printer lol.
