how is the 203 mounted ?

It's mounted to the RIS II, free floated from the barrel. The m203 rests on the rail near the barrel nut and is held in front by two tabs that rotate down when the bottom of the rail is removed.

Haven't measured exact length but it's in between the M4A1 and MK18 rail. Its the rare GL/SSC. I'd say it's about 11.5".

i remember the rail, not sure what it was in length etc... that is a cool build. what length barrel ? are those rails ever around ?

It's a 12.5" barrel. I've only ever seen 3 or 4 for sale in the last 5 years or so.

IIRC, the nominal spec was around 11.79, just enough to clear whatever can (KAC NTSS?) was prevalent in SOCOM use when SOPMOD was hatched. I think I've seen it described as "just long enough to mount the M203 but just short enough to clear the can." (Then again, there's also that persistent rumor about lo-pro GL/SSC's built with midlength URX II's... would be nice if we could get it put to rest one way or the other someday.)

I think you're right about the length. The shoulder of the barrel sits just outside the end of the rail, protruding a little bit more than a 10.3 on a mk18 ris II.

This one is getting a full upper makeover to clone correctness in a few days(taupe Ris, Colt Upper, and socom bbl In route) so figure I should show this one off while it still exists as it is...
