look at the picture the 11 mm clamps are in line with the bottom of the picatinny rail at the ends .I believe I have one of these. Tried using it on a Gamo gas piston rifle so I could use a red dot during the break in period. As I recall it did not clamp to the rail at all. I'll see if I still have it.
@skink (great name, by the way) I have a P-rod, an HW30 & that Gamo with dovetail rails. As I recall they're all slightly different. If I find that adapter I'll gladly dry fit it to any of those three & see if I think it's a good fit.I've tried a few different adapters from China and had the same issue. Couldn't get them to turn down on the 11mm
I bought one of those (or was it 4?).UPC: 848754002310
3/8 Dovetail to Picatinny Adapter Rail -Short adaptorView attachment 334458thought some might be interested $13 on Amazon
As far as airguns. I have an FX Tarantula that I need to scope. In the past it's been rimfire rifles by CZ and Sako I've had issues with. I prefer Burris ZEE rings usually so I have tried a couple different adapters to use those.@skink (great name, by the way) I have a P-rod, an HW30 & that Gamo with dovetail rails.

What dovetailed rifles do you have?
The problem I've had in the past was with adapters that were meant for 3/8 which I believe is common for American makers, but most European stuff is 11mm a lot of the same adapters will work on both as 11mm is just slightly smaller than 3/8, but some will bottom out without getting tight. at least the Chinese ones that I have tried. Those look like they would work on either as they would just bend more to fit. the slide type ones maybe not always though.Hawke makes a set of ultra love dovetail to picatinny adapters that are my go to.
