This Mossberg OEM Slug Barrel (brand part no. 92010) is a genuine factory replacement barrel chambered in 20 gauge, built for Mossberg 500 and Maverick 88 6-shot models. Measuring 24 inches with a fully-rifled bore, it comes as a complete scoped package, with a factory cantilever scope mount and a 3-9x40mm scope already paired to the barrel. That means shooters don’t have to source and zero a separate mount and optic; the barrel arrives ready to sight in. The barrel wears a traditional blued finish to match a factory Mossberg pump gun. Built by Mossberg, this combo is a direct upgrade for turning a field gun into a dedicated scoped slug gun.
