Welcome to the CPF const451.
What Curtis said about the clickie is correct but it may be a while until it comes to fruition. I wouldn't be surprised if petrev (Pete) gets involved with this also if any machined parts are needed for this project. He has some excellent connections with a machine shop that was used for the XTN-36 part of the HD-M6 project.
Also, keep an eye out for a used M6 if you want to save a little money or check out OpticsHQ for great prices on new lights.
Good luck surfing the forum.
