I was at the hardware store Saturday picking up some stuff to finish up one of Plinker's rivet jigs. Then I got to thinking about pressing the barrel out of my AMD 65. Right there in front of me were some brass nuts. On the face of the chamber it's not exactly flat so I figured I would grab a couple of different sizes and see what it would take to mill them down to fit.

I think this would work better than a stack of pennies and could be made fairly easily by using a dremel tool.

Here is a picture showing the dimensions of the nut.
