The SPY 007 Mini Picatinny Rail Accessories thread has sales info on the magnetic base. I just got more magnets so the mag base kit and the mag base fully assembled are both available. Keep in mind you need a GPA to use it with a 007 or Tri-V.
I do not sell the beads, please check with the titanium bead thread for beads. The glass beads I give away with a new light are simple to get at any local craft store. Or you can send me an SASE and I will send you a couple.
A 007 upgrade kit is far too complected and not something I am going to offer.
