Shotgun choke constrictions from Cylinder to Extra Full, in .005 inches (.127mm) increments let you precisely match your load to the shooting conditions, in a black oxidized finish. Long shotgun choke 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. Porting reduces felt recoil by 5%. Shotgun choke constriction is marked on band so there is no need to remove choke to verify size. Helical rifled Diffusion spreader tubes provide a pattern that is more open than cylinder.
**It is not recommended to shoot Federal's Black Cloud or any of their ammunition that utilizes their Flight Control Wad in ported chokes due to interference with its performance
