Extended Length, Competition Grade Tubes Improve Pattern & Accuracy
Choke constrictions, from Cylinder to X-Full, in .005" (.127mm) increments let you precisely match your load to the shooting conditions. Long tube extends beyond the length of the muzzle, features highly polished interior for less pellet deformation; reduced fliers and tighter patterns. Knurled grasping band speeds installation and removal. Choke constriction is marked on band, no need to remove tube to verify size.
