This Browning Superposed 12 ga (dated to 1961) came to the Service Shop for a cleaning and was also having selection issues. Chris tore it down and gave it a good clean & lube, removing rust and other gummed up oils. He replaced both mainsprings and the firing pins. He had to retrofit the firing pins to allow for proper protrusion for strong primer strikes. Chris then honed and polished both chambers and scrubbed corrosion from the bore. Finally, he stoned the inertia block shelf and sear tails to ease transition to the second barrel. The Superposed shined up like a new penny and no longer has selection issues. HUZZAH!
Fun fact: Did you know the Superposed was the first over/under shotgun to be produced ever? Production started waaaay back in 1931 and ended in 1986.
