Shotgun Choke Tube: This product is a removable shotgun choke tube designed for the compatible shotgun gauge and thread system identified in the title and specifications. It installs at the muzzle of a compatible shotgun barrel and is used to manage the shot pattern for its intended shooting application.

CODE BLACK SNOW PLOW tubes will extend out the end of your barrel 1 ½" and have an effective range out to 70 yards. The only difference between the Patternmaster CODE BLACK SNOW PLOW and Patternmaster CODE BLACK GOOSE is the color. Patternmaster applies a StrongBond White Powder Coat to the end of the SNOW PLOW tube to better conceal the tube during the fun, fast paced, Snow Goose mass casualty event. This is a ported tube.
