FN Auto-5 Light Twelve Grade I 12 Ga Semi-Auto Shotgun, 26" Vent-Rib Barrel, IC Choke, Belgian Made
This Belgian-built FN Auto-5 Light Twelve Grade I offers the classic long-recoil action John Browning designed, paired with a lighter receiver and barrel profile that trims weight without sacrificing reliability. Manufactured in 1955, it features factory Grade I scroll engraving, a hand-polished rust-blue finish, and a gold-washed trigger—hallmarks of mid-century Belgian production. The 26-inch vent-rib barrel is chambered for 2 3/4-inch shells and factory-marked Improved Cylinder, making it a versatile upland choice with collectible appeal.

What’s Included
- FN Auto-5 Light Twelve Grade I 12 Gauge shotgun
The Light Twelve variant pairs a thinner barrel and relieved receiver to shave weight, giving this full-size Auto-5 the handling of a smaller gun. Its adjustable bronze friction-ring system lets the shooter fine-tune recoil operation for lighter field loads or heavier high-brass shells.
Factory Belgian proofmarks and St Louis & Montreal import stamps confirm original production and import. The Grade I scroll engraving covers both receiver flats, adding understated elegance without distracting from the gun’s working-field pedigree.
The 26-inch vent-rib barrel promotes a fast sight picture, while the single silver-colored bead keeps the sight line uncluttered. An Improved Cylinder choke (**) offers a forgiving pattern for quail, grouse, or clay targets at moderate range.
Walnut furniture carries the classic round-knob pistol grip, cut checkering, and a ventilated recoil pad. Despite the noted crack in the fore-end, the stock remains solid, preserving the shotgun’s collectible status and shootable integrity.
