The steel receiver is roll-marked "Remington 870 EXPRESS MAGNUM" and uses twin action bars for smooth, positive cycling. As a Magnum receiver with an "M" serial suffix, it supports 3 inch shells in addition to 2 3/4 inch loads. A polymer trigger plate/guard and a cross-bolt safety complete the control layout.
The 18.5 inch barrel is plain (no rib) with a fixed cylinder choke and a single front bead. Barrel stamps read "12 GA. 2 3/4 OR 3" and "CYL," with an Ilion, NY barrel address. The configuration favors fast handling and straightforward sighting with a durable bead.
Capacity is 7+1 thanks to the factory +2 magazine extension and included barrel clamp. This setup corresponds to Remington Order No. 25077 and the Express Magnum Synthetic, 2-Shot Extension submodel. The shotgun retains the familiar 870 pump-action layout with a reliable, user-friendly design.
The furniture is black synthetic with molded checkering for grip and a rubber recoil pad for shouldering comfort. Length of pull measures 13.75 inches. Overall finishes are matte black for low glare and practical durability.
Markings and codes include a Remington barrel date code "XZ" (X denotes December). Country of origin is the United States.
