I have a RT Pro and i was told that all i had to do to fit the minimag body onto the rt body rail is to mill out a rectangular slot for the mini body. i milled it perfect and everything lines up, however, the stock body screw is too short to screw into the mini body.

Does the minimag have a longer body screw then the RT Pro or is it that the minimag body rail is thinner so that it can accomidate the minimag body??
