Sorry to the earlier inquirers, but I deleted a mess of directories while doing my weekly clean up. Gun is built on the United Sporting Arms frame, 6" Douglas barrel, 6 shot oversized full frame length cylinder, red insert front sight with serrated ramp and base, and rear sight similar to a Bowen/Bomar style sight, also serrated. Looking to trade for a shorter length barrel. e-mail me at dmadriaga@ascg.com if interested! Thanks!
