Browning Diana Grade 12 Gauge Invector-Plus Extended Modified Choke Tube

The Browning Diana Grade extended choke tube is a premium constriction option engineered specifically for 12 Gauge Browning shotguns chambered for the Invector-Plus thread pattern. Finished in a titanium nitride coating rated at 72 HRC, this Modified choke tube is built from heat-treated 17-4 stainless steel barstock for outstanding wear resistance and reduced plastic buildup during extended shooting sessions.

The Diana Grade line features a longer internal choke taper, making it an ideal match for back-bored 12 Gauge barrels. The titanium nitride surface treatment enhances surface hardness and resists plastic wad adhesion so shot patterns stay consistent round after round. As an extended tube, it protrudes beyond the muzzle for quick, tool-free swaps in the field or on the sporting clays course.

Offering a Modified constriction that delivers a 35% to 65% pattern percentage at standard yardage, this choke is a versatile middle-ground choice suited for upland hunting and a wide range of clay target disciplines. It is designed exclusively for Browning shotguns equipped with the Invector-Plus thread pattern and is not compatible with standard Invector or Invector-DS chokes.
