I'd like to put a M203 style 37mm launcher on my M4gery but the problem is that none of the several launcher companies I've contacted so far make the correct style launcher--they just have an M-16 A1/A2 model.  The M203 that's modified for use on an M4 has a shortened launch tube and  modified attachment rail to better fit the M4 barrel contour.  

Anyone know of a company that makes these, or eve a dummy version (airsoft, etc)?  Or am I just gonna have to try to find a good gunsmith/machinist to make the right mount?  Thanks for any help or advice you can provide.

A friend just got one from Mr.40mm,he sleves them to 37mm    http://mr40mm.com/

Thanks JPC.

How does your friend like the launcher? I saw it on the mr40mm website and it looks awesome--exactly what I'd wanted--but it's awfully pricey.
