What's Included
- FN Herstal Fusil Anson 16-gauge side-by-side shotgun
Built in Belgium by FN Herstal, the Fusil Anson uses the proven hammerless Anson & Deeley boxlock action. A Jones-pattern rotary underlever locks the action via double bites and a Greener crossbolt engaging a doll's-head rib extension, and the gun is extractor-equipped, with no separate automatic ejectors observed.
The 27-inch double barrels feature a solid matted rib topped with a single front bead for a clean, traditional sighting plane. Capacity is 2 rounds.
Controls are straightforward and classic: double mechanical triggers; safety configuration varies on these guns and is not specified here. The action type is break-action, consistent with the Anson & Deeley design.
Walnut furniture includes a straight, English-style stock with fine checkering and a splinter forend. European-style sling swivels are fitted (front on the bottom rib, rear at the stock toe-line). An aftermarket Pachmayr ventilated rubber recoil pad with a spacer stack is installed, and the length of pull measures 13.0 inches.
Markings include a French rib legend noting official smokeless powder proof under the Belgian system: "MECANISE PAR LA FABRIQUE NATIONALE D'ARMES DE GUERRE, HERSTAL, A L'EPREUVE OFFICIELLE POUR POUDRE SANS FUMEE." Country of origin is Belgium.
