Carlsons Delta Waterfowl Extended Choke Tubes are built for 20 gauge Browning Invector-Plus choke systems and are manufactured from 17-4 stainless steel. They use an extended parallel section to produce tighter, denser patterns than conventional choke tubes and are laser marked for easy identification. Each tube is knurled at the muzzle end to allow for quick installation and removal, and the set is backed by Carlson’s lifetime warranty. The tubes are designed to be used with steel shot; specific load-size and velocity limitations are noted below.
Key Specifications

Do not shoot steel shot larger than BB or any steel load faster than 1550 FPS through the Long Range constriction; loads that exceed that size or speed should be used with the Mid Range choke. The extended design and durable materials make this 2-pack a practical option for waterfowl applications where denser patterns and reliable construction are required.
