I just bought a TerraLux MiniStar2 Extreme TLE-5EX and I've installed it, but the head of my Mini Mag AA doesn't screw on as far. I tried taking off that plastic ring that is not supose to be removed. However, due to some epoxy/plastic around the two metal plugs the LED drop in is raised about 2mm higher than I feel it should be. Is there any way to modify the drop in so the Mini Mag AA head screws on further?
