Rosch Works is gone, does anybody make anything like their TM1 barrel light mount?

I’m looking to mount a flashlight to a rifle barrel… Ideally, a Surefire E Series light to a lightweight barrel.
The Rosch Works TM1 would be an excellent start, but they seem to have disappeared. Does anyone make anything similar?

A page full, although not light, the old school Surefire one works.

Are you stuck on the idea of barrel mounting for a particular reason? Just curious. If you are, I used to have some barrel mount stuff laying around that I never used. I can dig around if you have a reason and need for it.

I’d prefer not to, but unfortunately the rifle (ZM LR300) doesn’t give me many options.

Ahhh ok, the stuff I have someplace in boxes locks onto a FSB.

Yeah, that’s all I can find. Shame
