ok i have idea. make two huds. one with crosshairs that r normal the other with the hairs spread apart a bit. then make a blank image and name it the name of the guns crosshair in gamescore/guns folder. then, replace the crosshair image in da guns folder with the blank one. next, make a script with a few 'scancodekeypressed' actions that would call the hud when u moved back or crouched or whatever u want. then, attach the script to a completely inaccesible box, and there u go!
