Bismuth is a widely respected material in the shot shell industry due to its impressive performance, and it achieves its peak effectiveness when paired with the Raptor BIZ choke. This choke is a powerful enhancement to the Raptor Series, designed to optimize the performance of bismuth shot. Each choke tube is the culmination of years of development, incorporating the latest advancements in technology. Crafted from 17-4 PH US stainless steel, these chokes are built for superior strength and durability. Utilizing state-of-the-art machinery, they are precision-engineered to tolerances that exceed industry norms, ensuring exceptional reliability and consistency 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
