Dominate duck and goose season with tighter, more consistent patterns using the HEVI-Shot Hevi-Choke™ Waterfowl Extended Range Choke Tube (Model 85631). Engineered for Browning Invector-DS 12 Gauge shotguns, this precision-machined 17-4 stainless steel choke delivers maximum downrange pattern density and pellet energy — essential for clean, ethical kills at longer distances. Designed specifically for waterfowl hunters, the Hevi-Choke Extended Range model helps you stretch your shooting reach without sacrificing consistency or reliability.
Precision Patterning for Serious Waterfowl Hunters
When hunting over open water, flooded timber, or coastal marshes, every pellet matters. The HEVI-Shot Hevi-Choke Waterfowl Extended Range is engineered to deliver tighter, more uniform patterns — keeping more pellets in the target zone even at extended ranges. It pairs perfectly with HEVI-Shot’s premium tungsten, bismuth, or steel waterfowl loads, ensuring your shotgun delivers optimized performance for ducks and geese alike.
Extended range constriction provides the pattern control needed for long shots.
Improved pellet density means higher retained energy for clean, ethical kills.
Balanced constriction design for consistent performance across a wide range of non-toxic loads.
Rugged 17-4 Stainless Steel Construction
The Hevi-Choke Extended Range is built from 17-4 stainless steel, a high-strength, corrosion-resistant alloy designed to handle the rigors of wet, cold, and muddy waterfowl environments. It resists rust, deformation, and galling while maintaining its internal geometry season after season.
Durable 17-4 stainless steel ensures longevity even under heavy use.
Corrosion resistance for performance in rain, salt spray, or snow.
Precision CNC machining for consistent patterning and smooth barrel fit.
Extended Range Design & Black Finish
This choke features an extended, non-ported profile for better handling and easier removal. The black finish adds an extra layer of corrosion protection while blending with modern shotgun aesthetics. The extended design also allows for quick installation and removal by hand or with a choke wrench, even in the field.
Extended design improves handling and protection of barrel threads.
Matte black finish reduces glare and resists weather damage.
Easy installation/removal without tools in most conditions.
Optimized for Browning Invector-DS Shotguns
This Hevi-Choke is precision-engineered to fit Browning Invector-DS 12 Gauge thread systems, ensuring a secure lockup and repeatable alignment for optimal performance. Before installation, always verify your shotgun’s choke thread pattern — using the wrong choke type can damage your firearm or compromise safety.
