The Patternmaster Classic Mid Range is a unique tube that was designed to bridge the gap between our Short and Long Range tubes. There is no Code Black version of our Mid Range tubes. Internally they feature our patented Stud Ring technology to shorten the shot string and provide a more useful pattern while still being able to be effective out to 50 Yards. The Patternmaster Classic Mid Range is for the shooter who’s looking for a Modified pattern with the added impact of a short shot string. Patternmaster Classic Mid Range tubes come with a Matte Black Nitride coating for improved durability and glare resistance. All Patternmaster Classic tubes are crafted out of American made 17-4ph stainless steel, are heat treated to the optimum level for best performance and are safe and effective with Non-Toxic shot.
