I purchased a few stainless steel Lifestyle Mods, have used a couple at 18350, 18500, wanted to see if anyone knew of any place to get parts for these, firing switches for the bottom and 510 ring for the top, also thinking of trying to make some hybrids with the other tubes, so looking for possible RDA/RBA/RTA's that screw directly into a 22mm mod tube, any good ideas folks?
