Gents, I am in need of an old Hi Bev-L-Block front bead base. I cut back an old Auto-5, and it is patterning WAY high with the Colonial Arms base and standard bead. I need the higher base to lower the pattern. Brownells and Midway used to carry them, but they aren't available anymore. In fact, a Google search came up pretty much dry. I THINK they were made by Marbles, but am not sure. If you have one of these that you would want to part with, or know where to get one, I would appreciate the assist. Thanks!!
