Mossberg


The Mossberg BBL 500 12GA slug barrel with rifled bore and 24-inch length transforms your Mossberg 500 or Maverick 88 into a dedicated slug gun built for accuracy. If you hunt thick timber or need to reach out on deer or elk at distances where buckshot falls short, a quality slug barrel is one of the smartest upgrades you can make. This factory replacement barrel pairs a rifled bore—which imparts spin to foster-stabilized slugs for tighter downrange groups—with adjustable rifle sights, giving you a straightforward aiming solution that doesn't demand an optics budget.
The matte finish resists glint and plays nice with outdoor lighting, while the 24-inch profile balances sight radius and maneuverability in brush country. At 2 pounds 8 ounces, it doesn't add significant weight to your shotgun, keeping the gun pointable and quick to shoulder. This barrel is sized for a 3-inch chamber and works with the standard 6-shot magazine tube found on most Mossberg 500 and Maverick 88 platforms—no extended tubes needed or compatible here, so verify your receiver before ordering.
Swapping barrels on a Mossberg 500 is as straightforward as shotgun work gets: a cross-pin takedown and you're ready to hunt. Pair it with quality slugs, dial in your sights, and you've got a no-frills, no-nonsense slug gun that punches above its weight class. Whether you're a seasoned slug hunter or new to shotgun deer hunting, this barrel delivers the accuracy and reliability Mossberg has built its name on.

Yes, this barrel is designed as a factory replacement for Mossberg 500 and Maverick 88 shotguns equipped with a standard 6-shot magazine tube. It is not compatible with extended magazine tubes, so confirm your receiver configuration before purchasing.
This barrel is optimized for rifled-slug ammunition, which has a plastic sleeve around the projectile that engages the rifling. The rifling imparts spin, delivering better accuracy than foster-style slugs from a smooth bore.
