FX Streamline scope height questions

The top of the magazine is 14 mm from the “top” of the dove tail mount. My SL is .177 cal.

I’m using BKL medium rings and they provide 16.6 mm to top of rail to bottom of scope. The scope is a 40 mm with 52 mm OD in the front. Hope this helps.

This looks close to how mine is. Do you know center of scope to center of barrel?
