Shoulda asked the same question. Just bought the Rein thinking it may work without the IWC pic rail because it appears to not have a shroud as aggressive as SF. Perhaps I can get a hold of some longer screws and spacers to keep the light virgin tight to the weapon? Or dremel off a portion of the rail? ? Determined to make it work.
Hey, guys. Will the IWC mount with M600DF fit on the 8" Briley mount? Just ordered everything, but after studying photos, I'm concerned that it won't considering the Briley mount covers the barrel whereas the oem M4 mount tapers to the barrel leaving room for the tailcap..
