Patternmaster has been focused on improving shotgun performance since 1993, when founder Larry Leutenegger began experimenting with a new approach to choke tube design. Rather than relying solely on constriction, Patternmaster pioneered a patented stud-ring system designed to briefly control the wad and help create shorter, denser shot strings.

That innovation became the foundation of the Patternmaster system. Through years of research and development, the company found that the position of the stud ring inside the choke tube could influence pattern behavior, leading Patternmaster to describe its tubes by functional range rather than traditional constriction alone.

Today, Patternmaster offers a range of game-specific and performance-focused choke tubes, including its Code Black, Classic, Anaconda, Snow Plow, Sport Shooting, and Striker lines. The brand continues to emphasize precision machining, dependable materials, and field-tested engineering for hunters and shooters who want consistent performance across a variety of modern loads and conditions.

At its core, Patternmaster remains focused on the same idea that started it all: use engineering and innovation to help shooters achieve more predictable, effective patterns when it matters most.
