Mossberg 500 12 Gauge Two-Barrel Set – 28 in Vent-Rib Accu-Choke Field Barrel and 24 in Ported Slugster Barrel
This Mossberg 500 two-barrel accessory set pairs a 28 inch vent-rib field barrel threaded for Accu-Choke with a 24 inch Slugster barrel featuring a ported muzzle and a ramped front rifle sight. Both barrels are steel, chambered for 2 3/4 and 3 inch shells, and use the standard Mossberg 500 quick-change barrel ring with magazine cap detent. Made in the United States, this set equips a 12 gauge Mossberg 500 pump-action with versatile field and slug options.

What’s Included
- Barrel: Mossberg 12 ga 28 in Accu-Choke vent-rib field barrel (chambered for 2 3/4 and 3 in shells)

This set provides two purpose-built barrels for the Mossberg 500, allowing quick changes between a vent-rib field configuration and a dedicated slug barrel. The 28 inch field barrel is threaded for Accu-Choke tubes and uses a front bead on the rib for straightforward sighting on game or clays.
The 24 inch Slugster barrel adds a ported muzzle and a ramped front rifle sight for precise aiming with slugs. The shorter length balances handling while maintaining compatibility with 2 3/4 and 3 inch 12 gauge shells.
Both barrels are constructed from steel and retain the standard Mossberg 500 quick-change barrel ring with a magazine cap detent, supporting fast installation on compatible 12 gauge receivers. This system is designed for the pump-action Mossberg 500 platform.
Each barrel is chambered for 2 3/4 and 3 inch shells, offering flexibility in load selection. No serial numbers or dates are visible on the barrels, which is typical for Mossberg 500 accessory barrels.
