The bases are used and fit a large ring FN Mauser style action. See the photos of the back of the packaging for more information. The rings are 30mm extension med matte finish with all screws and torx wrench. I don't think I ever used the rings. At least it doesn't look like it.
The bases do not fit Mausers with the stripper clip hump.
