Answer to question three: Use a band-saw to cut off the missile launcher and to cut the bottom of the recon/retaliator  barrel (that will be your tactical rail). If you don't have a band-saw, you could use something else.

Use hot glue to glue the tactical rail on the part where the launcher used to be. Then seal the crack with epoxy.

You're done. I suggest you paint it now, unless you want the gray epoxy putty to be there.
