Hi there, I would appreciate any help you can provide. I received this used C5L with no original kit or parts/paperwork. I cannot seem to fit it onto any of my standard rails on several of my guns which leads me to beleive it is not a universal rail adaptor. Would someone with specific knowledge of this kit pls see the attached pic to verify if this one has the Universal rail adaptor installed for the standard 1913 pic rails or did mine come with one for some other specific model? Also, will someone pls tell me what size allen wrench is used for the windage/elevation adjustments? Lastly, where/how can I get a factory replacement kit for all the accessories that came with this light originally? All I really need is a universal rail adaptor and the tools for the rail replacement and elevation/windage adjustments... I sent Viridian an email but hoping to get an answer/replacements sooner rather than later. Thanks in advance!
