Beretta (HP) Ported Black Oxide Shotgun Choke - 20 Gauge

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. 

 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.
