Exploiting the 'old C' switch retainer thread, in the 'old C mag', I cut it down & screwed the tailcap into the little bit left...woha a NOC m@g!!
Using 1/ CR123A & SHO micropucks, I will be offering RX0H 1 & 3 lux units driven @ 500ma each... the trilux version should last 30min at least...(still testing)
It is a very easy mod to do...a great little pocket rocket w up to 6k lux ( single version)...
enjoy
