What’s Included
- Remington 870 Magnum 12-gauge 30-inch steel vent-rib barrel with fixed Full (F) choke and single front bead (barrel only)
Made for the Remington Model 870 Magnum platform, this 12-gauge barrel is chambered for 3-inch shells when installed on a 12-ga Magnum receiver. It is a barrel-only component intended to swap directly onto compatible 870 Magnum receivers.
The configuration is set up for field use: a 30-inch length, ventilated rib, and a single front bead. The muzzle is unthreaded, and the choke is a fixed Full (F), providing a consistent constriction without interchangeable tubes.
The rollmark reads "★12 GA. MAGNUM FOR 3 IN. SHELLS." Remington 870 barrels are not factory-serialized; any number provided with this item is an inventory or control identifier rather than a serial number.
Constructed from steel, this barrel is designed for the pump-action Model 870 Magnum system and retains the classic bead-sight setup that many hunters and shooters prefer for straightforward target acquisition.
