I am preparing for my first M*g85 mod.... im wondering why I cant just start with a Rechargeable Maglite to begin with instead of a standard 3D Maglite? Wouldn't all I need be a 9AA to 3D battery adapter (FiveMega) and Bi-pin WA1185 bulb? The Rechargeable Maglite already has a metal reflector, the lens is glass, and the bulbholder already accommodates a bi-pin?
