Franchi Extended Mobil 20ga IM Black Choke 51575

The Franchi Extended Mobil 20ga IM Black Choke is an extended‑length Improved‑Modified choke tube intended for 20‑gauge Mobil/Instinct style barrels. The IM constriction tightens patterns for mid‑to‑long range work—useful for waterfowl, turkey at moderate distances, or clay targets—while the extended profile provides extra clearance at the muzzle for smoother shot exit and easier follow‑ups. Finished in a durable black coating for corrosion resistance, it installs using standard choke threads and is removable with a choke wrench.
