What’s Included
- Remington Model 10R Riot Grade 12 Gauge pump-action shotgun
This Model 10R retains the hallmark bottom-loading and bottom-ejecting design, paired with a takedown system for convenient maintenance and transport. Its 20-inch cylinder bore barrel supports quick handling, while the 2 3/4" chamber aligns with common 12 gauge loads.
The action is pump-operated with a stated capacity of 4+1. A short magazine tube with a single barrel band defines the riot configuration. The safety is located forward of the trigger in the trigger guard, consistent with Model 10 design.
The shotgun wears a blued finish over its steel receiver and barrel. Furniture consists of a plain, uncheckered walnut stock with a semi-pistol-grip and straight comb, matched to a ribbed walnut forend. The buttplate is marked REMINGTON UMC, and the length of pull measures 13.5 inches.
Riot Grade configuration details include the absence of a trench-gun heat shield or bayonet mount. The Model 10 series uses U-prefix serial numbering and was produced in the United States. Key setup highlights include the Cylinder Bore and 2 3/4" Chamber.
