Side-by-side double-barrel shotgun. Chambered for 12-gauge, with 28" ventilated rib barrel, choked Full and Modified. Features sidelock action, with double triggers and extractors. Finish blued and case colored, with checkered walnut stock. Offered by Marlin between 1968 and 1973.These are less desirable than earlier models because of manufacturing expedients used. Investment cast receiver rather than machined forgings were used. Cyanide case-hardening replaced bone charcoal hardening and aluminum ventilated ribs were used. A thin brown polymer layer was used to create the fit between lock plates and buttstock, which is a departure from traditional fitting.
