The Franchi Extended Instinct 16ga C Choke is an extended-length cylinder choke tube for Franchi Instinct 16-gauge shotguns. With essentially zero constriction it produces a very open, fast-spreading pattern appropriate for very close-range shots, dense cover, and situations where minimal pattern tightening is desired. The extended body gives extra clearance at the muzzle for smoother shot exit and quicker follow-ups; construction is steel with a corrosion-resistant finish and standard threading for removal/installation with a choke wrench.
