Patternmaster Code Black Duck Choke Tube Browning Invector Plus 20 Gauge

Patternmaster Code Black Duck Shotgun Choke Tubes are a unique in design. The Duck is the same constriction as the classic Long Range. This design ensures quicker release of gas that will result in reduced pressure and recoil that effectively separates the wad faster and produces an even more symmetric shot pattern. Code Black tubes have been coated with a bronze titanium blend to better withstand heat and corrosion. Once again Patternmaster has gone to the limits to make a top-of-the-line shooting accessory for the extreme hunting experience. The ducks had better watch out!WARNING: This tube is not to be used with slug ammunition, or ammunition that contains a wad/shot cup design as "flight control" or "in flight separation." For best results, Ballistic Performance LLC, recommends ammunition velocities below 1550fps.NOTE! Any defective Patternmaster items MUST be returned directly to Patternmaster.
