Mossberg 12 Gauge Slug Barrel for Remington 870, 24 Inch, Blued

The Mossberg 12 Gauge Slug Barrel is a 24-inch, fully rifled replacement barrel built to turn a standard Remington 870 pump shotgun into a dedicated rifled-slug gun. Made by Mossberg, it ships with adjustable rifle sights already installed and a blued finish to match factory Remington 870 barrels. The rifled bore stabilizes rifled slugs for tighter groups at deer-hunting ranges than a smooth bore can deliver, and the fixed sight picture lets you dial in windage and elevation without adding an optic. It is not compatible with 3.5-inch Magnum-chambered Remington 870 models. This barrel is a straightforward way to add a dedicated slug-gun barrel to an existing 870 without buying a second shotgun.
