Does anyone know if there is an off the shelf ring option available these days?

LGM / others:
For mine, I used the ScopeStuff 6.3" #CR63.
I had to re-felt them, and I'm pretty sure I used the 3/16" felt, but that was slightly too thick for the tube. Some careful shaving with a razor (about 1/4 to half the thickness of felt removed) and they fit great.
It was time consuming, and I kinda had to figure it out as I went.... but it worked. Before, it was a bit tight... since these don't have the slotted swing-out style locking clamps. (ala most other vendors)
As a side note.. I've thought about using the 1/4 x 20 holes on the ring tops, and maybe rig up some sort of sling system for quick sweeps. Then just grab it and carry it out like that, but then again.... my neck doesn't like that thought. It may work though, for those brave / crazy enough to try. I think the AstroScan had a sling too, right?
Hope this is of help for those wanting rings for theirs, they are almost a necessity for using this scope on a GEM mount IMHO.
Best,
