What’s Included
- Mossberg 500 12-ga 30 in vent-rib barrel, fixed FULL choke with front bead (chambered for 2 3/4 and 3 in shells)
- Mossberg 500 12-ga 28 in vent-rib barrel, Accu-Choke threaded with front bead, MOD choke installed (chambered for 2 3/4 and 3 in shells)
- Mossberg 500 12-ga 24 in vent-rib barrel, Accu-Choke threaded with front bead, FULL choke installed (chambered for 2 3/4 and 3 in shells)

The three vent-rib barrels (30, 28, and 24 in) each use a single front bead for a clean sight picture. The 30 in barrel is fixed Full choke, the 28 in Accu-Choke barrel ships with a Modified choke installed, and the 24 in Accu-Choke barrel ships with a Full choke installed. This mix supports upland, waterfowl, and clay applications with readily understood choke performance and bead-sight familiarity.
The 18.5 in barrel is a non-ribbed, matte gray, defensive configuration with a fixed Cylinder bore and an integral stand-off breacher at the muzzle. It is purpose-built for close-range use and rapid handling while maintaining the same 2 3/4 and 3 in chambering standard as the longer barrels.
All four barrels are steel and marked 12 GA. Each attaches to a Mossberg 500 pump-action receiver using the standard Mossberg 500-pattern lug and a captive takedown screw for straightforward swaps. The set combines both fixed-choke and Accu-Choke threaded options, giving you immediate flexibility without sourcing additional barrels.
Chambering is consistent across the set at 2 3/4 and 3 in, ensuring ammunition compatibility when changing barrel length or choke type. The inclusion of both ribbed and non-ribbed profiles lets you tailor the gun’s balance and sighting style to the task at hand.
