If you can get a hose clamp taped inside so you don't scratch it around your rotary switch or tape the rotary switch and tighten the clamp till it gets solid ,then you won't tear it apart while trying to unscrew the cap making it more solid so you can put out a bit more power on the top screw cap.Find some thing like a silver dollar that fits snug in your slot so you don't strip it and snap the end of the vise grip as tight as you can on the twist nut on the hose clamp,don't go crazy on the pressure and use another set of vise grips to snap onto what ever fits tight in your slot.It has to be even level pressure as you turn so you don't bust your rotary switch, I don't want you to reck your scope so this is just a thought that may work. When you tighten the clamp make sure it makes even contact 360 degrees around the rotary switch so not to bend anything.The clamp sides maybe to wide touching the cap so this may not work.Don't start cutting things until you hear from aimpoint or send it to them for the work .GOOD LUCK
