I'm trying to determine if the current Steyr Professional has the same receiver contour and is drilled with the same spacing as its predecessor, the Model M Professional. The predecessor I'm referring to is a mid 80's vintage rifle. I have tried Leupold technical without any clear answer.

These folks sell the EAW mounts and are very knowledgeable about Steyr's:
