Browning Invector-DS Choke Tube Features The Browning Invector-DS Modified extended choke tube fits precisely into the Invector-DS system found on select 16 gauge Browning shotguns delivering a consistent repeatable pattern shot after shot. Modified constriction strikes a balance between tight and open patterns making it well suited to upland birds that flush at varying distances throughout a hunt. The extended design protrudes slightly beyond the barrel s muzzle giving shooters a visual cue of which choke is installed at a glance. Stainless steel construction ensures the tube resists corrosion and wear even after repeated exposure to weather and powder residue. Finished in black the extended profile also makes the tube easier to grip and remove with a choke wrench compared to flush-mounted tubes. The added length provides extra surface for the shot column to stabilize before leaving the barrel which can help tighten pattern consistency. Hunters who move between dense cover and more open fields will appreciate the versatility Modified constriction offers across a single outing. The Browning Invector-DS Modified extended choke tube is a practical addition for 16 gauge shooters who want reliable all-around pattern performance.
