The Carlson Optima HP 12ga Sporting Clay Full choke tube combines precision machining in 17-4 stainless with a design that delivers superior patterning for clay target and field use, featuring a 25% larger parallel section to produce more consistent patterns than conventional tubes. This choke is knurled at the end for quick, tool-free removal and laser-marked with the exact constriction for easy reference in the heat of competition or field days. Built to support a wide range of ammunition, it accepts lead, steel, copper-plated, nickel, Hevi-Shotshells and buckshot, giving shooters flexibility across hunting and sporting scenarios. The thin-wall construction enhances flow for tighter patterns, though steel shot cannot be used in the Modified, IM, Full, or EF constrictions due to the design. All Carlson Sporting Clay Choke Tubes are backed by a lifetime warranty, offering long-term reliability and confidence on the range or in the field. Ideal for competitive clay targets and upland or waterfowl setups, this choke delivers improved density and consistency without sacrificing versatility or ease of use.
