The Carlson's Delta Waterfowl Extended Choke 20 Gauge is purpose-built for duck and goose hunters who demand tighter, denser patterns downrange. Made from 17-4 stainless steel, this mid-range/long-range choke tube leverages a 25% longer parallel section than conventional designs to deliver more consistent shot patterns—a real advantage when birds are working your spread or crossing at distance. Whether you're hunting from a blind, boat, or field, this choke gives you the density and reliability steel shot demands.
The extended parallel design means pellets stay grouped tighter as they travel, translating to cleaner passes and more confident shots on waterfowl. The knurled end allows quick removal and installation without tools, and laser-marked constriction and gauge labeling on both the end cap and body eliminates guesswork in the field. Carlson's engineered these tubes specifically for steel shot performance—a critical detail for modern waterfowl hunting—and they've backed that commitment with a lifetime warranty.
This choke is compatible with Winchester, Browning Invector, Mossberg 500, Weatherby pre-1993 models, and Ruger Red Label shotguns. If you run a Winchester SX-2, SX-3, or SXP, note that those shotguns use Browning Invector Plus tubes, which differ from this standard Invector pattern. Always verify your shotgun's choke system before purchase. Follow Carlson's recommendations: don't shoot steel larger than BB or loads exceeding 1550 FPS through the long-range constriction; use the mid-range tube for heavier or faster loads.
