The pursuit of perfection in shotgunning demands equipment that matches skill with innovation. Here we present a modified 12-gauge choke tube crafted from robust stainless steel, enhanced by a titanium nitride finish. This combination offers not only formidable durability but also unparalleled protection against wear and fouling. The design incorporates an extended taper within the Invector-Plus system, making it particularly suited to back-bored barrels—a testament to its advanced engineering. Meticulously heat-treated prior to machining, this accessory promises longevity under rigorous use. With a surface hardness rated at an impressive 72HRC, expect minimal maintenance thanks to reduced plastic buildup. The precision-engineered concentricity delivers exceptional pattern consistency—an indispensable feature for those who demand excellence. Moreover, practical considerations haven't been overlooked; this component extends beyond the barrel's end, allowing effortless changes when time is of the essence. Whether you're honing your craft or entrenched in competitive pursuits, this piece stands ready as a reliable companion on your shooting journey.
