So today i recieved my M1x i bought off ebay. I am a big fan of the 18650 so i also purchased the smooth body cell extender. The M1x came in OD when i orded it natural. The extender will not screw in all the way ( Ive soon relized this is a problem with different generations) and the light will not even turn on. So with all this said, does anyone know were i can get a second or third generation M1X in natural finish with a combat style extender also in natural? Thanks
