Tinkering around, non rifle related, and found a need for 1.5” rings, preferably 1-2” tall also. Is there such a thing and, if not, something similar? For this use cheap plastic ones would be best.

Might look at light mounts…roll bar light mounts. I’m not familiar with any scopes that have that big of a tube.

34mm is 1.3”

35mm is 1.378”. You could probably find something like a 1.5” pipe hanger or stand off or something like that.

Yeah they make 36 and 40mm rings. You’re needing 38mm. No such animal that I’m aware of.

Thanks, guys, I found some pipe clamps online that will do what I need!

You have me curious.

What is the project?

Check aviation/aerospace distributors. Marman V-Band Machined Flanges may work for your application. They will not sell to you, but you can find what you are looking for and determine the part number. From there, do a google search and find what you are looking for in the used, secondary market place.
