Franchi Extended Mobil 12ga F Knurled Choke 50893

The Franchi Extended Mobil 12ga F Knurled Choke is an extended screw‑in choke tube for 12‑gauge shotguns, designated Full (F) to produce dense, long‑range patterns. The extended profile increases the effective constriction length, helping tighter patterns at longer ranges - useful for waterfowl or long upland shots. The knurled outer surface allows easy hand installation and removal. Constructed from stainless/alloy with a durable dark finish, it’s intended to fit standard 12‑gauge threaded muzzles; confirm thread pitch and whether your barrel uses standard or proprietary threads before purchase or installation. Follow the manufacturer’s torque recommendations and safety steps when fitting and never fire slugs or steel shot from a choke not approved for that load.
