I talked to Brandon today at 440Source and he said the ROL gasket was discontinued about a year ago.

I think I'd like to get something with the stainless ring around the cylinder.
Any other ideas? 4.380 bore. No Cometics, my surfaces aren't smooth and they're out of my price range.

Looks like the Corteco would be part #55655HG, who sells these?
