So I came accross a used up Maglite that was broken and, what's there to do? Mod the crap out of it of course!!! So, SST-90, Custom bezel, 18650 battery, direct drive.... some stripes. I cheated on this one by slipping the threaded part of the mag lite into the barrel so I would not have to thread the back after shortening it up. Used JB Weld to hold together. I am now threading them.
