For many years, Turkey hunters have trusted the tried-and-true Undertaker choke in the spring woods. HS has decided to up the game in order to support the ever-changing turkey ammo. Introducing the Undertaker Pro, this modern design has been tested and perfected to keep your pattern tight and on target way down range. Undertaker Pro has a unique internal groove technology that helps separate pellets from the wad and also stops wad spinning and focuses more pellets on target. This extended choke keeps gasses away from the shot string through the radical porting design. Choke is rated for Steel, Led, Bismuth and TSS.
