This is a 1970 Belgium made , Light 12 gauge, Browning A5-2 barrel set. (Barrels are -26" and 28" vent rib) The gun is immaculate - (case w/key, instruction booklet, wood, bluing etc...) It will shoot 3" magnum and 2 3/4, 12 gauge steel or lead shells (See diagram bellow) I purchased the shotgun from an estate collection and to my knowledge, it had never been fired. I have fired it twice. Since then, it has been in my collection.
