: I want to build a new 16" m4 upper, but I'd like to use the kac short ris instead of regular M4 grips. Does the fh have to be removed from the barrel to install the kac ris? Can I use a heavy under the guards barrel or is it too heavy to fit the kac ris? Is there another short ris system preferred to the kac, or is the kac the standard? |
