This is a factory Remington 870 12-gauge, 20" fully rifled slug barrel with iron sights. It features a ramped front blade and an adjustable rear leaf on a raised base for precise sight alignment without added bases or rails.
The chamber accepts both 2 3/4" and 3" shells. The barrel is made from carbon steel with a matte black oxide-type finish, giving it a uniform, low-glare appearance consistent with factory production.
It uses the standard 870 barrel extension and includes a soldered magazine-tube ring for proper fitment on the Model 870 pump-action platform. The configuration is non-cantilever with no scope base.
The muzzle has a plain crown, and there are no choke tube threads, aligning with its fully rifled design for slug use. The barrel carries an Ilion, NY manufacturer rollmark.
