The Raptor Series Turkey Choke is designed to simplify what you need for turkey hunting due to utilizing a single constriction based off of each individual model. This choke is the ideal option when using TSS or lead. It also works great with any length of barrel. This choke features green as well as machined claw marks for extra grip. The Raptor Choke Series uses new technology to deliver a hotter core pattern at distances that are sure to impress. These choke tubes are built from years of product development and innovations using the highest advanced technology available. They are made out of 17-4 PH U.S. Stainless Steel. We use state of the art equipment and machine to tolerances way beyond the industry standard. *Over-Shotguns can have a RRaptor choke in only one barrel. The design of the choke does not allow for placement in both barrels.*
