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 12 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.
Invector-Plus choke tubes fit only Browning shotguns designed for Invector-Plus and are NOT for use in shotguns showing Standard Invector or Invector-DS on the barrel(s).
