What's Included
- Western Field Model SB-300 12 Gauge side-by-side shotgun
This SB-300 follows the familiar Stevens 311 pattern, delivering a sturdy boxlock action with straightforward controls. The manual tang safety and double triggers provide simple and reliable operation that many shooters prefer in a classic side-by-side.
The 30 inch barrels are made from selected forged steel and joined by a solid, matted rib for a clean sighting plane. A brass bead front sight gives a clear reference, and the bores are chambered for 2 3/4 inch shells, as indicated by the factory proof markings.
Extraction is handled by a one-piece central extractor designed to lift both shells for easy removal. Capacity is two rounds, consistent with the field-focused layout of the platform.
The shotgun uses a steel receiver and a wood stock with a pistol grip, uncheckered surfaces, and a ribbed buttplate. The 14.0 inch length of pull offers a traditional fit, and the receiver and barrel markings confirm factory proof and model origin.
