Bismuth has become a favored material in the shot shell industry due to its exceptional performance, particularly when paired with the Raptor BIZ choke. As an integral part of the Raptor Series, this choke represents a culmination of years of product development and technological innovation. Constructed from durable 17-4 PH US stainless steel, it offers unparalleled strength and reliability. Manufactured using state-of-the-art equipment, these choke tubes are precision-machined to tolerances that far exceed the industry's standards, ensuring superior consistency and performance with every shot. Over-Shotguns can have a Raptor choke in only 1-barrel, the design of the choke does not allow for placement in both barrels, ensuring optimized performance in one barrel
