Been looking at all the cool mods done to carbines. I plan on throwing a paint job on mine soon, still working on a design. Anyway, on Long Shot Mfg. web site, they have some really cool barrel shrouds with an integrated rail. Just wondered if that could be used as a front mount for a MBUIS? Only way I've seen it is with the rail facing DOWN. I have a BSA red dot scope on there now, would love to have a co-witness as a back up.
