Just a quick hint for most users out there trying to get their Bezel off.... First unscrew and remove the Rear half of the light. (the portion that holds the battery and tailcap). Then try using the floor or a rubber boot or shoe to unscrew the bezel. Some people have said doing this releases the pressure inside the tube, due to it being waterproof.
Just wanted to give some advice. I really didnt want to hear anyone destroying this wonderful flashlight
just to get a GITD o-ring under the bezel. Because if thats the case, just PM me and I'll give you my address to send it to. :wave:
