The scope that is currently mounted on this Bavarian half-stock is a Schmidt & Bender 3-12 x 42. Like the previous gentleman, I do not remember what brand the rings are. I measure the centerline of the 300 mm. tube to be +/- 1.25" above the dovetail groove.
I would consider them to be the equivalent of high rings.
The other two 85's that I have in house are both Bavarian Carbines, one the "S" short action (308 win) and the other a "M" medium action. I do not own any 85's with any of the four other action choices so I cannot speak in reference to issues in regards to their ejection.
The ring/bases on the 30-06 Springfield are low Opti-locks
The rings/bases on the 308 Win. are Leupold WAM's.
