Description
The Mossberg 90800 is a factory OEM 12 Gauge slug barrel designed as a direct-fit replacement for the Mossberg 835 Ulti-Mag shotgun. At 24″ long, this dedicated slug barrel is equipped with traditional adjustable rifle sights for precision aiming on slug shots and a fixed cylinder bore suited to Foster-type and other standard 12-gauge slug loads.
The barrel carries a classic blued finish to match factory 835 Ulti-Mag components and installs directly onto the existing Ulti-Mag action with no modifications required, giving shooters a quick way to convert their shotgun between birdshot and a dedicated slug-hunting setup. The longer 24″ sight radius paired with adjustable iron sights makes the 90800 a natural fit for deer hunters and anyone running the 835 in slug-only zones.
As a genuine Mossberg OEM part, the 90800 delivers factory-spec fit, finish, and headspace for reliable function when swapped onto the 835 Ulti-Mag action.
