Picked this up uber cheap a few years back, it's a Military issue turn in but I have not been able to sort out the actual model. Would like to know if it's possible to upgrade the tail cap / pressure switch as well as update the bulb to LED. Everything works but in it's current configuration I have no real use for it. Searching for A05866 has proved fruitless...maybe my interweb sleuthing skills just suck, any help?
