MikeV, Never seen a device to hold up the rear sight but after looking at mine I would think that one could easily be made from something as simple as a tin can by cutting out a piece, folding the tin over the sides of the rib, with one end wedged against the recess where the site drops into, then bend a couple of "legs" up to hold the site up. The spring tension on the sight should hold it place and if not add a small hobby magnet to hold it in place. I know I probably made this about a clear as mud (sorry). Where in the "midwest" might you be located. I am just north of the Twin Cities in MN...
