I've taken a liking to the Bushness Holoscope but cannot determine which mount to order for my Anaconda. Is there a really good source for mounts that spells that out clearly?

That, of course, should be BUSHNELL rather than Bushness!

B Square makes a pretty good revolver mount for anything with the Weaver type attachment.

Look in the supply house catalogs and the various scope mount makers - there's usually a chart such as for Weaver, Leupold, etc that tell which of their mounts will fit a particular firearm.

I bought the scope from Weigand's and they had the scope base listed for each scope. Its an easy web-site to use, and good prices too.
