Ported System (Holes): The part of the choke that protrudes from the barrel has rows of holes. These allow some of the gases to escape outward before the shot exits.
Result: Reduction of recoil (kick) and limitation of barrel rise, allowing the user to bring the gun back on target more quickly.
Barrel Extension: The choke screws internally into the barrel, but its body protrudes by 2 centimeters. This extension helps in the gradual tightening of the load, often leading to a more uniform distribution of the shot.
Surface Treatment: It features a special stainless matte coating. This property is functional, as it eliminates light reflections on the metal (glare), so the user's field of vision is not disturbed.
