The Browning Diana Grade 12GA choke tube is a Light Modified extended choke engineered for Invector-Plus compatibility. Manufactured from stainless steel with a titanium nitride finish, this choke features a longer taper inside the Invector-Plus design for use with back-bored barrels. The stainless steel barstock undergoes heat treatment prior to machining to ensure durability and performance.
The titanium nitride surface delivers 72HRC hardness for excellent wear resistance and reduced plastic buildup. Precision manufacturing ensures absolutely perfect concentricity for superior patterning. The extended design protrudes beyond the barrel for convenient removal and installation.
Specifications: 12 gauge, Light Modified choke, extended style, stainless steel construction with Invector Plus threading, dimensions 1.40 X 4.45 X 6.20 inches (height 1.4000, width 4.4500, length 6.2000).
