Carlson's Choke Tubes 07155 Delta Waterfowl Extended Choke 20 Gauge Mid-Range 17-4 Stainless Steel

The Carlson's Choke Tubes Delta Waterfowl Extended Choke in 20 gauge is purpose-built for mid-range waterfowl shooting—the 25- to 40-yard sweet spot where most duck and goose hunters connect with their birds. Unlike standard choke tubes that can take a beating from steel shot, this extended choke moves the stress point away from your barrel entirely, protecting your shotgun from the wear that comes with repeated steel loads.

What sets this mid-range extended choke apart is its longer parallel section, which does two things: it tightens your pattern for better pellet density at distance, and it reduces flyers—those erratic pellets that drift outside your main shot group. That design also lets you step up to larger steel shot sizes without sacrificing performance, giving you flexibility in load selection when conditions change.

Built from 17-4 stainless steel with a knurled extension for reliable hand-on installation and removal, this tube delivers the durability you need in harsh waterfowl environments. The blue finish resists corrosion from wet conditions and prolonged exposure. Carlson's backs every tube with a lifetime warranty, so you're covered for the life of your shotgun.

Frequently Asked Questions

What shot distance is this choke tube designed for?

The mid-range extended choke is optimized for waterfowl shooting at 25 to 40 yards, the effective range where most duck and goose hunters operate.

Can I use all steel shot sizes with this tube?

Yes, all steel shot sizes can be used in this mid-range choke tube. For the long-range version, shot size is limited to BB and smaller, and velocity must not exceed 1550 FPS.

Why does the extended design protect my barrel?

The tube extends 3/4 inch outside the barrel, moving the main wear and stress point away from your shotgun's bore. This eliminates the barrel damage that can result from prolonged steel shot use.

Is this choke tube right for my 20 gauge?

This choke is manufactured for 20 gauge shotguns. Always verify that your shotgun accepts removable choke tubes and confirm the proper gauge before installation.
