Scope base for double rifles

[skydiver386]

One thing that puts me off buying a double rifle vs a bolt gun is the sights. My eyes simply aren't what they used to be and I'm much more confident with even the lowest magnification scope than any open sights or red dot.

So my question is, are there decent scope base and ring systems for double rifles? The Merkel 140 in 500NE might be a doable option with a Swaro Z8i+ .75-6x20 I have on hand.

The Merkel K5 mounting system is especially elegant and looks to be very strong, but obviously this is different from what I see on the Merkel 140. Is there a QR one piece ring and base system that uses simple levers, or are they all the twist lock variety?

I really like mine: ERA on pivot mounts

Which means I can swap between scope, red dot and irons without loss of zero

I had Bill Gostomski to install Talley mounts on my doubles. They work perfectly.
