The flash hider/grenade launcher combo has a washer that is punched up into a cutout in the FH body to hold it in place. Use a screw driver to pry down the retaining piece so the washer is flat, put a nail through one FH hole and out the corresponding side and use it has a handle to turn off th FH and retaining nut. Then slide off the range ring. The rifles shoot better without the range ring anyway, it does funny things to the barrel harmonics.
