Abstract:
A shotgun choke system consisting of four zones, a the first zone being a compression or constriction zone; the second zone being a stabilization zone; the third zone being a second compression or constriction zone; and the forth and final zone being a second stabilization zone. The shot package is compressed and constricted into a tight, uniform shot delivery package, and the wad package is completely separated from the shot package. The shot package therefore leaves the barrel of the choke, first, while gasses from the shot escape through a muzzle break and the wad package exits following the shot package, drastically reducing recoil and improving the shot pattern over prior art choke embodiments.
