What’s Included
- Browning Auto-5 Standard Weight 12 Gauge semi-automatic shotgun
The receiver serial prefix M denotes a 1957 Standard Weight Auto-5 made in Belgium. The blued steel receiver carries factory scroll engraving on both sides and bears the correct MADE IN BELGIUM and Browning Arms Company St. Louis Mo & Montreal P.Q. markings. Receiver top serrations complement the gun’s classic humpback profile.
The 28" Special Steel barrel is solid and matted ribbed, marked "Special Steel – 12 Gauge – Shells 2 3/4" and coded ** for a fixed Modified (M) choke. A single front bead provides a clean sight picture. The barrel address style (St. Louis & Montreal) indicates a later Belgian barrel was mated to this 1957 receiver, as noted in the provided details.
Its long-recoil semi-automatic action uses the friction-ring recoil system and includes a magazine cut-off, with an external bolt handle for straightforward operation. The capacity is 2+1, and the chambering is 2 3/4". This configuration reflects the well-known Auto-5 operating characteristics.
The walnut furniture includes a round-knob pistol grip stock and a finger-groove forend, both with checkering for secure purchase. It wears an FN/Browning hard-rubber logo buttplate, and the length of pull measures 14.25". The metal shows a blued finish, and the sighting setup is a simple single front bead paired with the matted rib.
