Updated "Mega Pistol" by GunCAD Dev Nopel (creator of the M1337 5.56 Gatling Gun). Originally designed by a nerdy Asian guy who invented a new type of 3D Printing, the design was found to be deficient and lacking. 40 rounds of .22lr on tap in the most unergonomic way possible, but it is cool looking.
