Carlsons Tubes Sporting Clays Choke Tube Features The Carlsons Tubes Sporting Clays Choke Tube uses a skeet constriction to open the shot pattern early giving shooters a wider effective spread for the close fast-breaking targets typical of skeet and sporting clays stations. Built from stainless steel the tube resists corrosion and holds up to repeated cycling without the pitting that can affect softer alloys over a season of heavy use. Its flush design sits inside the muzzle rather than extending past it keeping the barrel s profile and swing weight unchanged for shooters who prefer a factory look. The Invector thread pattern matches the Stevens 301 directly so installation is a simple thread in and tighten with no gunsmithing required. At 1.5 inches long this tube is sized for quick swaps between rounds or stations without digging through a bag for a longer alternative. The stainless construction means it can be run in wet or humid conditions common to outdoor clay courses without worrying about surface rust developing between cleanings. Because it is built specifically to fit the Stevens 301 shooters get a reliable drop-in option rather than a universal tube that may not seat or pattern consistently. For anyone shooting .410 sporting clays or skeet with a Stevens 301 this choke tube is an affordable way to dial in pattern performance for the game.
