Interesting to see that other people would be interested ina MiniMag with larger reflector as well.
Here is my design of a middle part, that is using a MiniMag body, and a Mag2D bezel, together with a carclo 2 degree narrow beam optic and a Badboy sandwich. This optic is not as powerfull as the stock Mag optics, but it is better then anything else, and you can't beat the thickness of I think 10mm. I love tight and very focused beam the carclo produces - the hotspot is 3 times brighter then the stock MiniMag reflector.
In this link I originally asked for details how to do the threading to realize this design - there are some solutions there.

My problem however is I have absolutely no time to do it, work picked up so much that I am swamped and will be in the future.
So if anybody is interested in the design (emachineshop.com data format) let me know. Also this thread here contains information about how to do the threading

Of course no guarantee for anything. But I think it's a good basis to start out with - design needs some minor tweaking, and defenitely re-measuring to see whether I got it all right, since it is only a draft. However after that is done, add the threading, and it should be fine. So if you have the time and means to do it, let me know.
My only condition is that when you do it that you have a part produced for me as well (I pay for the costs of my part). To whoever decides to do it, I would even throw in a Carclo2 degree optic for this person. If you decided to do a larger batch, someone offered several carclos to me for a reduced price.... let me know and I'll put you in touch.
If anyone is interested send me your email address and I'll mail you the emachineshop.com data file.
