I have an MC51 with SBS conversion...it basically looks like a 7.62 MP5 SD6. I wanted to add a light to the front so I used this:

Theres a local Surefire authorized dealer near my house and they were able to special order the part for me for $60USD. The only problem was it took 8 weeks to get here since its typically shipped with and given priority to the Millennium series lights. Maybe you could just call Surefire directly. It works like a charm though...very sturdy and VERY spiffy when installed.
