reflectors for MT-G2

Hey guys im working on a design on a copper P60 for a MT-G2 and few other leds and was wondering what is the smallest reflector that works best with a MT-g2 emitter ?

or any for the newer Led's ? i like to get few so i can have my machinist to machine to fit them perfect

I bored my out with a drill

i dont need to drill them since there not made yet, but ill be working around the reflector once i find a good reflector for the MT-G2 or any other LED

I’ve been itching to try an mt-g2 in this reflector designed for the P7 from KD. I just recently ordered them so I can’t speak to how well they pair.
