Browning Diana Grade Invector-Plus 20 ga Extended Choke Tube – Light Modified


The Gold Standard for choke tubes. The longer choke taper inside Diana Grade Invector-Plus choke tubes improves pattern performance. These tubes are for use with back-bored barrels on 20 gauge shotguns. They offer a superior construction from stainless steel bar stock that is heat treated prior to machining. The use of a titanium nitride surface with 72HRC hardness provides excellent wear and reduced plastic buildup, and they look beautiful on the muzzle end of your Browning Citori.
