1/4-20 to pic/arca clamp?..

[PlinkIt]

Ok so I'm trying to find one of the combo clamps that will attach to both picatinny and arca that will mount on a leveling base with a male 1/4-20 stud sticking outvthe top of it...

Apparently my Google-fu is weak this week

Doesn't need to be suitable for firearm just for holding spotting scopes & auxiliary equipment

Anyone have some experience with such a clamp?

Well, this will work.

Then add any clamp with a 17s interface, like the RRS SC-ARC (combo Arca + picatinny).
