Mossberg 500 12 Gauge 3" 18.5" Breacher Shotgun Barrel - Cylinder Bore, Matte Blued

The Mossberg 500 Breacher Shotgun Barrel is a factory replacement 18.5" stand-off barrel purpose-built for 12 Gauge Mossberg 500 and Maverick 88 6-shot shotguns. Featuring a rugged matte blued finish, this barrel is chambered for 3" shells and is designed to deliver reliable performance in tactical, home-defense, and law-enforcement applications.

A fixed cylinder bore choke provides a wide, unconstricted shot pattern ideal for close-quarters use, while the integrated front bead sight offers fast, intuitive target acquisition. The matte blued steel construction resists corrosion and glare under harsh lighting, and the breacher-style muzzle features an extended standoff that aids in tactical entry and reduces muzzle blast back at the shooter.

This replacement barrel drops directly onto any compatible Mossberg 500 or Maverick 88 6-shot action, making it a versatile upgrade for owners who want to swap barrel configurations without investing in a complete second shotgun.
