If there is anyone who has any information regarding a scope level bubble which clamps around the scope tube would you please let me know where I might purchase one. I have herd the term "spirit bubble" but am not sure if that is a brand or just slang for a scope level. Thanks for your help.
Brownell's sells at least three different versions. The ScopLevel, the Mounting Solutionas unit, the B-Square (which mounts on your Weaver/Picatinny base, but needs to have clearance under the scope to fit, so beware), etc.
Go here, and then search for MWG level (in the keyword field, and it will pull up a page of options: http://www.brownells.com
it's not about need in the USA -- it's about WANT
