Mags can be a worm hole of customization that you never get out of. AGD, Tuna and Big Evil can all tech them for you and I know there are others as well. you might contact Tuna(Tunaman5@verizon.net) and see if he can build you one from parts he has, they won't be new but you will receive a complete working marker that way.
There are plenty of new parts left . I have enough to build 4 CNC Xmags and about 10 Standard Emags. After that, the new parts will be gone forever.
