Sako 85 (7x64) / Zeiss V6 3-18 x 50 / Optilock XTRA-LO 30mm.
The Optilock rail is low compared to a Picatinny rail.
The ejector/extractor design is prone to induce a failure to eject the spent case with big scope erector. I have no issue with a Schmidt & Bender 7x50 Klassik which has a slimmer tube design (still 30mm).
Use higher rings to solve the issue (LO or ME).
