What's Included
- Browning Auto-5 Light Twelve Grade I 12 Gauge semi-auto shotgun
Made in Belgium by FN for Browning during the St. Louis import period, this Light Twelve carries the import marking "BROWNING ARMS COMPANY ST LOUIS Mo." and a receiver roll-marked "Light Twelve." The configuration reflects the classic Auto-5 profile and features that collectors and shooters expect from this era.
The long-recoil-operated action provides the signature Auto-5 cycling characteristics. A magazine cut-off lever on the left side of the receiver allows quick control of the feed system, and the gold-colored trigger adds a distinct period-correct detail.
The 30-inch plain barrel is fitted with a single brass bead and the receiver top has a matted sighting plane for a clean visual reference. Chambered for 2 3/4-inch shells, the capacity is 4+1 (where legal/without plug).
Walnut furniture includes a round-knob pistol grip stock with cut checkering, a hard-rubber buttplate, and a matching walnut forend. Length of pull is 14.5 inches, and the blued finish on the steel receiver and barrel complements the traditional Browning aesthetic.
