Remington 870 Express Barrel The Remington 870 Express Barrel is chambered in 20 gauge with a 2.75 inch chamber matching the specification required to fit a standard Remington 870 Express receiver. Measuring 20 inches in length the barrel is fully rifled a design specifically intended to stabilize sabot slug ammunition for improved accuracy at hunting distances. This rifled configuration makes the barrel particularly well suited to deer hunting in states that require shotgun only hunting zones. Made in the USA the barrel reflects the quality and fit Remington has built its reputation on for decades of 870 production. Swapping in a dedicated rifled slug barrel allows an 870 Express owner to convert their existing field or home defense shotgun into a purpose built deer gun without the expense of buying an entirely separate firearm. The blued steel finish provides classic styling along with solid corrosion resistance when properly cared for. Because this barrel is built specifically for the Remington 870 Express platform installation is as simple as removing the factory barrel and dropping this one into place. For 870 Express owners looking to add dedicated slug hunting capability to their shotgun this 20 inch rifled 20 gauge barrel is a direct effective upgrade.
