Ncstar 30mm cantilever ring mount weaver style - NcStar 30mm Cantilever Ring Mount Weaver Style

Seems to be holding up ok for a cheaper ring set. I just needed something for my plinking rifle. The off set is very helpful. I had a set of tall weavers also But couldn't get them positioned quite right. These helped a lot. Will they last for years and years not sure but for now they seem to be doing fine and have not moved or loosened I did add a dap of blue threadlock though.
