Carlsons Sporting Clays Choke Tube Features The Carlsons Sporting Clays Choke Tube is precision machined from 17-4 stainless steel which gives it a bright stainless finish that resists corrosion and wear from repeated use at the range. Its 25 percent longer parallel section throws more consistent patterns than conventional choke tubes which means shooters see fewer fliers and tighter more predictable spreads on clay targets. The Improved Modified constriction is lasered directly onto the end of the tube so shooters can confirm the choke at a glance without guessing or checking paperwork. A knurled end makes the tube easy to grip for quick removal or installation between rounds or when switching loads. Built specifically for the Stevens 301 in .410 GA with a 1.5 inch flush fit this choke tube is compatible with lead shot steel shot copper plated shot nickel shot Hevi-Shot and buck shot. Shooters should avoid steel shot larger than BB in this Sporting Clays tube since tighter constrictions are not rated for larger steel pellets. Because the parallel section runs longer than a standard flush mount choke this tube throws tighter and denser patterns than typical flush chokes on the market. The Carlsons Sporting Clays Choke Tube is available for sale at GrabAGun for Stevens 301 owners looking to dial in their .410 pattern for sporting clays.
