Description

Titanium nitride for durability and hardness. Optimal patterns for Invector Plus shotguns.The Gold Standard for choke tubes. What makes it different? First . . . 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 and 20 gauge shotguns. But 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 very, very good on the muzzle end of your Browning Citori.
