Hey guys, first post here. Ive got to say that this is an awesome community, so much info! Im in the market for my first serious flashlight and ill either be going with a Ra Clicky or a Novatac EDC. The Ra obviously comes standard with clip up carry but the Novatac doesnt. Ive read that one can install the standard clip between the bezel and body to reverse the carry but I was wondering If I would need to buy an extra o ring to insure water resistance? Would changing the distance between the bezel and body possibly allow water to enter, and if so would the standard EDC o rings be the proper size to fix this? Thanks!
