Thanks yal. I was so confused (still but less so now, lol). My mixed Stingray from angelcigs barely fits whatever battery I'm using and can not use a safety fuse. My new brass Nemesis from FastTech finally arrived and I had the opposite problem. Had to use a safety fuse and a magnet to stop battery rattle. The beauty ring looked like it was part of the top cap and I had to use sure-grip gloves to remove it after reading this thread.
Too bad it won't work on my Stingray.
