Manufactured at the FN Belgium plant, this Magnum Twelve Grade I exemplifies the Belgian Auto-5 lineage with factory scroll engraving and polished blued steel throughout. The receiver carries Belgian proof and inspection marks and is clearly marked "Magnum Twelve," confirming its magnum configuration.
The 28-inch "Special Steel" barrel wears a vent rib with longitudinal matting and a single front bead for a clean sight picture. It uses a fixed choke and is chambered for 3-inch shells. The top of the receiver also features longitudinal matting.
Stocked in gloss-finished walnut, the shotgun includes a round-knob pistol grip with cut checkering, a matching walnut forend, and a ventilated recoil pad with a black spacer. A Browning trade-mark medallion is present, and the classic humpback profile underscores the model’s signature look.
Function-focused details include the long-recoil, semi-automatic action, a 4+1 capacity, and a left-side magazine cut-off lever. Length of pull measures 14.5 inches, and the polished blued steel receiver and barrel complement the traditional field configuration.
