regards to you as well Rick. Somehow I have a feeling that we are not talking about the same rings though. These look like the "economy version" of whatever brand they are (doesn't say) and definately aren't part of any "system" as far as I can tell and have no inserts. They just seem flimsy. Now I'm no ring expert but have had difficulties with rings of similar nature, that is, to me, there's too many moving parts. anyways. take care.
