What’s Included
- Mossberg 500 12 ga 28 in Accu-Choke vent-rib smoothbore barrel with front bead; standard barrel ring with magazine-cap stud
- Mossberg 500 12 ga 28 in Accu-Choke vent-rib smoothbore barrel with front bead; barrel ring includes integral sling swivel stud

Designed for Mossberg 500-series 12-gauge receivers, this set covers common field and slug roles with three purpose-built barrels. The 24 in barrel is fully rifled for dedicated slug use and carries a front sight ramp, while both 28 in barrels are smoothbore field barrels with vent ribs and front beads.
Both 28 in field barrels are threaded for Mossberg Accu-Choke tubes, adding choke versatility to the smoothbore pair. The rifled barrel is configured specifically for slugs and does not use a rib.
All barrels are chambered for both 2 3/4 in and 3 in shells. Construction is steel throughout, providing durable service on compatible pump-action 500-series receivers.
Barrel ring configurations are distinct across the set: one 28 in barrel uses a standard ring with a magazine-cap stud, the second 28 in barrel includes an integral sling swivel stud in the ring, and the 24 in rifled barrel uses a standard ring with a magazine-cap stud.
Sighting is straightforward: the smoothbore vent-rib barrels feature front bead sights for field shooting, and the fully rifled barrel employs a front sight ramp to support slug work.
