Carlson's Barrel Remington 870 Express 12 Gauge 3" 18-1/2" Rem Choke Ramped Front Sight

Looking to refresh or customize your Remington 870 Express? The Carlson's 18.5" replacement barrel for Remington 870 12-gauge shotguns gives you a clean, compact platform perfect for home defense, tactical shooting, or shotgun sports. Built from certified ordnance-grade 4140 steel with a chrome-lined bore, this barrel is engineered for durability and reliability. The ramped front sight and matte finish keep things practical and quick-target ready, while the factory-threaded Rem Choke system lets you dial in the shot pattern you need—from tight patterns to wide coverage depending on your choke selection.

Swapping barrels on your 870 is one of the simplest upgrades you can make, and Carlson's barrels are known for fit and accuracy. The 18.5" length strikes a balance between maneuverability and sight radius, making it a go-to choice for shooters who want a versatile, no-nonsense workhorse. Chrome-lined bores resist corrosion and extend barrel life, especially if you're pushing volume through it at the range or in the field.

Whether you're building a dedicated home-defense setup, want a shorter barrel for your hunting rig, or just need a spare, this barrel integrates seamlessly with your existing 870 components. The included Rem Choke (17-4 stainless steel) handles standard choke tubes, so you're ready to shoot right out of the box.
