It combines a 20-inch plain barrel with a fixed Improved Cylinder choke, a matte parkerized finish, and forged internal parts predating later MIM components.

The 20-inch riot barrel keeps the shotgun compact and maneuverable while the fixed Improved Cylinder choke delivers wide patterns ideal for close-range applications.
A black finish on the steel receiver and barrel resists glare and corrosion—features prized by law-enforcement agencies in the 1980s.
The classic 12-groove corn-cob hardwood forend and straight-grip stock give the gun its recognizable Remington riot-gun profile. A ventilated recoil pad and factory sling-swivel stud add practical comfort and carry options.
Built on a magnum-rated receiver, this 870 reliably chambers both standard 2 ¾" and high-power 3" shells, expanding ammunition choices without modification.
