NICE ! I USED to have two of those - I sent one to c0ldshadow....nice pointers, I have not been able to get mine to open up, so I cannot tell you if it is moddable or not...sorry about that :'(
i just got one of those yesterday, it was very easy to take apart and mod everything is threaded
senkat have you unthreaded the end of it at all there may be a small blob of purple glue keeping it shut.
The end of mine now has "teeth" marks in it from some vise-grips ! I could NOT get that sucker apart...Aaron_inc - are you a weightlifter or something ? LOL !!! It would not budge for me at all !!! :'(
