I want to install a 37 MM Launcher on my M4 barrel,and was wondering my mounting options,I hate the handguards that are used with them.Will it mount up to a Knights Armarment Ras,or what I would like to do is mount it to the Arms Sir.Also can I get some pictures of everyone who has time to post'em?Thanks guys

I recently contacted ARMS about this question and the S.I.R. All that is needed for mounting a 37mm with the S.I.R. is the removal of the lower half of the handguard. Granted you still have to have the 203 cutdown in the barrel, but all the mounting hardware still functions the same as mounting an actual M203. No big deal.

You also need to remove the nut/yoke which snugs the sir down against the barrel nut, as this is where the rear of the launcher sits, which makes the sir a bit less sturdy. Chris
