i am trying to change the rings on my gun to put the scope lower on the barrel, but the redfield rings(turn in style) screws wont budge so that i am unable to get the scope off...i even stripped them a little where the allen screw goes in...somebody evedently used locktite on them or something ......thought about trying to drill them out...any suggestions..i dont want to damage the leupold scope on top....thanks
