i've had this idea for a while now.
several months ago i made a mockup of one, just pressfit together, and have been planning to make a better one ever sence.
as it goes, i've been held back by gear problems with the lathe, time problems, etc.
as soon as my current workload clears up this is on the top of my to-do list.
the mag threading is an issue, but it's possible to machine a normal mag head down and pressfit it tightly inside a new piece...you wouln't even be able to tell /ubbthreads/images/graemlins/smile.gif
