Put money down on a 500c 20 gauge. This one has twin action bars, vent rib barrel and screw chokes. When I do get it home I'll give you more information about it.
Got it home today! According to the forum here it was built in 1997. 26" vent rib barrel with 2 bead sights. Wood stock with a few scratches in it. Some scratches on the receiver but I can live with them. Action is smooth, locks up tight. Most importantly the safety works! Its definitely been in the field and will continue to do so. And it will never be lonely.
