The Carlson's Delta Waterfowl Extended Choke Tube in 20 gauge is purpose-built for long-range waterfowl hunting—specifically designed to deliver tight, consistent patterns when steel shot connects beyond 40 yards. If you're pushing your effective range on ducks and geese, this long-range choke tube gives you the shot density and reliability that makes the difference between a clean harvest and a miss.
What sets this choke tube apart is its extended parallel section, which concentrates the shot string for denser patterns and fewer flyers downrange. The 17-4 stainless steel construction resists corrosion from saltwater environments and repeated steel shot use, while the extended design projects 3/4" beyond the barrel—protecting your shotgun's threads and bore from the wear that comes with high-volume waterfowl hunting. The knurled extension makes it easy to install and remove by hand, even in cold weather with gloves on.
This is Carlson's premium long-range offering, engineered to handle the velocities and shot sizes typical of modern waterfowl loads. It's a solid choice if you shoot steel loads regularly and want proven patterns at the distances where most pass-shooting opportunities happen. The blue finish and stainless construction mean it'll hold up season after season in the marsh.

Frequently Asked Questions
What shot sizes and velocities can I use in this long-range choke tube?
Steel shot loads up to BB size are compatible, but do not use steel shot faster than 1550 FPS through this long-range choke tube.
Will this choke tube work on any 20 gauge shotgun?
Yes, this is a standard 20 gauge choke tube and will fit any 20 gauge shotgun with removable choke tubes.
What's the advantage of the extended design?
The 3/4" extension projects beyond the barrel, protecting your shotgun's bore and threads from damage caused by prolonged steel shot use. The longer parallel section also creates denser patterns with fewer flyers, which improves consistency on distant waterfowl.
Is this choke tube good for close- and mid-range shooting too?
This tube is optimized for long-range performance (40 yards and beyond). For versatility across multiple distances, Carlson's offers close- and mid-range steel shot choke tubes as separate options.
