OK...remove the flashider. It has three 'keyways', sort of like the letter "Y", that fix it to the barrel.
You can change the position of the FH so the bayo-mount is on the upper site of the "Y', 120 degrees out of synch.
Of course, now the sight dovetail is in also 120 degrees out so you must use a "Navy" style gas-lock sight as your front sight.
This is of course, just an exercise to show that you can mount a bayonet to your shorty,
but you probably won't want to do this unless you are an extreme bayonet fan!!! ;-)
