Remington 870 Express Shotgun Surplus Barrel — 12 Gauge | 18.5" | 3" Chamber | Smoothbore | Blued

Sold Individually

Upgrade or replace your Remington 870 Express with this factory-spec smoothbore barrel, delivering the versatility and reliability the 870 platform is legendary for. The 18.5" barrel length strikes the ideal balance between maneuverability and velocity retention, making it equally at home in the field or as a dedicated home defense configuration.

The 3" chamber accepts both standard 2¾" and 3" Magnum shells, giving you the flexibility to run everything from light target loads to heavy-hitting buckshot and magnum field loads without changing hardware. The smoothbore construction handles the full range of 12-gauge ammunition — birdshot, buckshot, steel shot, and Foster-style rifled slugs — with no restrictions.

Finished in a classic matte blued steel, this barrel is built to Remington's factory tolerances and drops directly onto any compatible 870 Express receiver with no modifications required.
