Carlson's Choke Tubes 07157 Delta Waterfowl Extended Choke 20 Gauge Long Range 17-4 Stainless Steel

The Carlson's Choke Tubes 07157 Delta Waterfowl Extended Choke for 20 gauge shotguns is built for serious waterfowl hunters who need extended range and tight patterns on ducks and geese. Machined from 17-4 stainless steel, this extended choke delivers the corrosion resistance and durability that wetland hunting demands—especially important when you're working saltwater marshes, swamps, or rain-soaked conditions where standard chokes can corrode quickly. The extended length gives you a longer forcing cone transition and helps optimize shot pattern density at distance, giving you confidence when birds are working the outer edges of your effective range.

This choke is designed to fit Beretta and Benelli Mobil-threaded 20 gauge shotguns, making it compatible with a wide range of popular waterfowl guns. The 17-4 stainless construction resists rust and pitting far better than standard steel, so it'll hold up to repeated salt-water exposure and wet-field conditions without degradation. If you're running a 20 gauge for ducks or geese and want to push your effective range or tighten your pattern when conditions demand it, this is the choke built to handle it.

Installation is straightforward on any shotgun with Mobil-compatible threads. Keep one in your gun bag as a dedicated long-range waterfowl tube, or rotate it in based on conditions and distance to your expected shot opportunities.

Frequently Asked Questions

What shotguns will this choke tube fit?

This choke is designed for Beretta and Benelli shotguns with Mobil-compatible threads in 20 gauge. Check your shotgun's manual or choke tube threading to confirm compatibility before purchase.

Why stainless steel for waterfowl hunting?

Waterfowl hunting often means exposure to water, mud, and salt spray. 17-4 stainless steel resists rust and corrosion far better than standard steel, so your choke won't pit or degrade even with repeated wet-field use.

What's the advantage of an extended choke for long-range waterfowl?

Extended chokes have longer length and optimized internal geometry that helps create tighter, more consistent shot patterns at distance. This gives you better performance when birds are working the outer edge of your effective range.
