What’s Included
- Remington 870 Express Magnum 12 Ga shotgun with 24" Mossberg fully-rifled barrel
- Williams adjustable iron sights (rear sight absent as noted)
The installed Mossberg Slugster barrel is carbon steel, fully rifled, and optimized for sabot slugs, delivering enhanced accuracy over smoothbore configurations. Its 24-inch length strikes a balance between maneuverability and velocity, making it suitable for dense woods or blind setups.
The hardwood stock and matching pump fore-end feature pressed checkering for a solid grasp, plus a factory recoil pad to manage magnum loads. Length of pull measures 14 inches, accommodating most adult shooters without modification.
The matte black oxide finish on the steel receiver and barrel reduces glare in the field and resists corrosion. Twin action bars and a cross-bolt safety continue the 870’s reputation for rugged, uncomplicated operation.
With Remington’s interchangeable-barrel system, the shotgun can quickly convert to bird, turkey, or defensive roles simply by swapping barrels (additional barrels not included).
