The Gold Standard for choke tubes. The longer choke taper inside Diana Grade Standard Invector choke tubes improves pattern performance. These tubes are designed for barrels with .410 bore choke constrictions. 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.
