Specifically designed for top performance when used with lead and copper plated lead shot. The Hunter's Specialties HS Strut Pro Staff endorsed Undertaker Full Turkey Choke Tube gives you maximum consistency with a longer parallel super full choke for maximum performance. Machined for accuracy, it places 90 percent of the shot in a 30 circle at 40 yards. Each choke tube features a blued finish and a knurled end for easy removal (although a final tightening with a choke tube wrench is recommended to prevent the choke tube from loosening while shooting). These 3 long choke tubes fit all 2-3/4, 3, and 3 1/2 chambered shotgun barrels that are listed below.
