Carlson's New Gold Ported Sporting Clays choke reduces recoil and at the same time reducing muzzle jump making follow up shots quick and easy. These chokes feature a 25% longer parallel section in the choke which allows for tighter, denser patterns, with less flyers another words more pellets on the target. The extended portion of the choke tube allows for quick and easy removal and insertion. When using steel shot do not shoot steel larger than BB through any choke tighter than full. These choke tubes have a Gold finish and carry our full lifetime warranty.
