Highcom security rails

I'm hoping someone can help me out with this dilemma. I currently have a highcom security striker achhc helmet and I would like to get some rails for it. But there's a problem I was gifted a set of ops core ach rails and they did not fit the way I was hoping. They hung down a little low and being in an airborne unit the JM's are picky when it some to stuff like that. So does anyone know what rails I should get so they do not go past the bottom? Attached are some images to show what I am referring to.
