FN Auto-5 Standard Weight 12 Gauge, Belgian 1955, Solid Rib, Fixed Full Choke
Made in Belgium in 1955, this FN Auto-5 Standard Weight brings together the classic long-recoil action John Browning designed with factory Grade I scroll engraving and a less common solid rib barrel. Its 29.5-inch Special Steel tube is fixed to a Full choke, and the shotgun retains its original round-knob walnut furniture and blued finish. Collectors and shooters alike will appreciate the H-prefix serial confirming mid-50s Belgian production and the smooth function that has kept the Auto-5 a field favorite for decades.

What’s Included
- FN Auto-5 Standard Weight 12 Ga shotgun
This shotgun is the Standard Weight version, balancing a stout steel receiver with manageable swing weight for a full-size 12 gauge. The long-recoil system absorbs recoil energy then returns the barrel and bolt separately, producing the signature Auto-5 feel.
Its Special Steel barrel measures 29.5 inches, wears a solid rib instead of the later-issue ventilated rib, and is cut with a fixed Full choke—ideal for tight patterns on waterfowl or upland birds requiring reach.
The receiver carries factory Grade I floral scroll engraving on both sides, complemented by the high-polish blued finish. Belgian proof marks add authenticity and confirm origin.
Walnut furniture features a round-knob pistol grip, cut checkering, finger-grooved fore-end, and a steel butt-plate. The 14.5-inch length of pull suits most adult shooters while preserving period-correct dimensions.
A magazine cut-off switch on the receiver’s left side allows quick chamber clearing without unloading the magazine—a hallmark Auto-5 convenience that remains fully functional here.
