Thread: Lesson Learnt - Cheap Rings

Brother in law mounted a scope in Tasco 'World Class' rings that were so far out of 'true' the scope wouldn't adjust. Someone told me they'd bent the scope, and whether that was true or not - I don't know.. I got those rings and mounted them on a BRNO 600 reciever with integral grooves, then polished up a 1" bar, that spanned the two rings, put some valve grinding paste on it and lapped those rings with shim spacers between the halves until they were true to each other. By the time it was done they were well oversize - sufficiently so it took a couple of wraps of film negative to take up the windage.

Never seen rings so badly made.
