Mossberg OEM 20 Gauge 24-inch Slug Barrel – Adjustable Sights, Fully-Rifled

This Mossberg OEM Slug Barrel (brand part no. 92062) 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 is purpose-built for slug ammunition rather than shot, and the rifling meaningfully improves accuracy over a smoothbore barrel firing slugs. Adjustable rifle sights let shooters dial in point of impact precisely, and the barrel wears a traditional blued finish to match a factory Mossberg pump gun. Built by Mossberg, this barrel is a direct upgrade for turning a field gun into a dedicated slug gun.
