Carlsons 87004 Remington Choke System Replacement Barrel 12 Gauge 18.5" 3" Matte Blued 4140 Steel for Remington 870

The Carlsons 87004 is a 12 Gauge replacement barrel purpose-built for the Remington 870 pump-action shotgun. Cut to a compact 18.5" overall length and chambered for 3" shells, this threaded barrel drops onto a standard 870 to give it a tactical, defensive, or utility configuration without modifying the host firearm.

The barrel is constructed from certified ordinance-grade 4140 steel with a chrome-lined bore for long-term corrosion resistance and easier cleaning under field use. A matte blued exterior finish minimizes glare, while a ramped front sight provides a snag-free aiming reference suited to a bead-style sight picture. The muzzle is threaded for the Rem Choke system and ships with a cylinder (C) choke tube installed.

This is a drop-in replacement barrel accessory only; the host Remington 870 shotgun is not included.
