The Rizzini USA BR460 IPS is a 12 gauge over/under shotgun built around 30-inch vented rib barrels. It uses an interchangeable choke tube system, so the same gun can be tuned for clays or field work by swapping tubes to match the shot pattern needed. The over/under configuration gives a traditional double-barrel firing sequence in a long-barreled package suited to sporting clays and upland hunting.
