I am trying to CAD some riser blocks for my FWB P70 so I can print a couple and figure out what height I need before ordering some. I am having a lot of trouble finding the exact dimensions of the dovetail, from what I understand it is 11mm and is inclined 60degrees out to a wider top. I unfortunately do not have rifle with me and have been having trouble finding the dimensions of either the wider top, or the vertical depth of the rail.

Does anyone have a manufacturers's drawing of the rail I can get some measurement off of?

Or if anyone has done this before and knows the dimensions that would very helpful.

Cheers
