Mossberg BBL 500 12GA Slug Barrel with 24" Rifled Sights - Matte Finish

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.

Frequently Asked Questions

Will this slug barrel fit my Mossberg 500 or Maverick 88?

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.

Do I need to use slugs in a rifled barrel?
