Designed to throw denser and tighter patterns than conventional choke tubes, Carlson's Waterfowl Chokes have a 25 percent longer parallel section, allowing them to throw more consistent patterns. They are manufactured from 1704 stainless steel and are knurled on the end for quick and easy installation and removal with no need for a choke wrench. Constriction and choke size are laser marked on each tube.
