Remington Field Grade Rifled Barrel Features The Remington Field Grade Rifled Barrel replaces the smoothbore barrel on a Remington 1100 with a fully rifled bore purpose-built for sabot slug accuracy. The rifling imparts spin to sabot slugs as they travel down the 21 inch barrel stabilizing the projectile for noticeably tighter groups compared to a smoothbore bird barrel firing the same ammunition. A 2.75 inch chamber matches standard 12 gauge slug loads and the blued steel finish provides durable protection against the elements during field use. This barrel transforms a general-purpose 1100 into a dedicated deer rifle without the expense of purchasing a separate firearm. A cantilever scope mount ships pre-installed on the barrel itself which means the optic stays zeroed to that specific barrel even when swapped on and off the receiver. This setup lets a shooter keep a dedicated slug barrel with its own scope ready to go for deer season then switch back to a standard barrel and choke tubes for other hunting or clays use. Mounting the scope directly to the barrel rather than the receiver also improves consistency since the barrel and optic move as a single unit. The Remington Field Grade Rifled Barrel is available for sale at GrabAGun for hunters who want dedicated slug accuracy from their existing Remington 1100.
