  • Improved Cylinder
  • Nickel chrome moly
  • Extends beyond end of barrel for easy removal and even tighter patterns
  • Proprietary differential banded gas seal eliminates residue build up and makes chokes easy to remove and install
  • Integrated spring suspension holds the seal tight, yet allows expansion against the barrel wall for a perfect fit and a smooth transition for the shot column entering the choke
