The Express Fully Rifled Deer variant pairs the proven 870 action with a slug-dedicated barrel. The 20-inch tube is fully rifled and rollmarked "FULLY RIFLED 1 TURN IN 35 INCHES," optimized for modern sabot or rifled slugs. The matte finish reduces glare in the field, and the knurled magazine cap on the standard-length tube makes takedown straightforward.
Factory rifle sights include a ramped front with a metallic blade and a barrel-mounted adjustable rear, providing a clear sight picture. The receiver is drilled and tapped and comes with a scope mount installed, offering an out-of-the-box path to magnified optics if desired.
Chambered for 12 gauge with a 4+1 capacity, this example carries the "870 EXPRESS" receiver rollmark and a serial suffix "M" indicating a 12-gauge Magnum receiver. Per the barrel guidance, it is suitable for 2 3/4 or 3-inch shells in Magnum receivers.
The hardwood stock and matching fore-end feature pressed checkering for grip, paired with a ventilated recoil pad and a 13.75-inch length of pull. Controls include a cross-bolt safety, and right-side ejection ensures compatibility with common field use. The steel receiver in matte blue/oxide finish underscores the classic 870 build.
