What’s Included
- Remington 870 Magnum 12 Gauge 30" vent rib barrel with fixed Modified choke
Built for the Remington Model 870 Magnum platform, this 12 gauge barrel is marked on the left side "12 GA. MAGNUM FOR 3 IN. SHELLS," confirming its 3-inch chambering. A separate "MOD." choke stamp denotes its fixed Modified constriction. The bore is excellent, offering a clean, mirror finish.
The 30-inch length and ventilated rib provide a long, consistent sighting plane, complemented by the factory-style front bead. The muzzle is not threaded for choke tubes, and the choke is fixed rather than tube-compatible.
Construction is carbon steel with a polished blued finish that matches traditional 870 factory aesthetics. The rollmarks are clear and legible, and the overall presentation is consistent with a well-cared-for, lightly handled barrel.
The 870-style barrel extension includes the proper locking recess and extractor relief cuts for correct interface with 12 gauge 870 Magnum receivers. This is a straightforward, factory-style replacement or upgrade for users needing a 3-inch Magnum barrel with a fixed Modified choke.
