Just drill off the heads take the base off and take some needle nose pliers and turn out screw.I've had to do this a couple times. It's very easy.Just make sure you have your rifle held firmly and have good control of drill and bit so you don't slip.
Yeah, that's what I normally with a mill to hex heads too (see my post at the top of the thread); just thought GD might know a quicker way.
