Browning Midas Invector-DS Improved Modified Choke Tube Features The Browning Midas Invector-DS Choke Tube is machined from stainless steel for long-term corrosion resistance in wet field and marsh conditions. Its improved modified constriction tightens the shot pattern beyond a standard modified choke giving hunters extended effective range on birds flushing at moderate distance. Built specifically for the Invector-DS choke system it threads directly into compatible Browning 12 gauge shotguns without need for an adapter. The stainless construction also resists the fouling and pitting that steel shot and modern non-toxic loads can cause over a season of use. This choke tube is a simple direct way to tune shot pattern performance without replacing the barrel or the shotgun itself. Swapping chokes for the target species and distance is one of the most cost-effective upgrades a shotgun owner can make. The Midas line is built to the same tolerances as Browning s factory choke tubes ensuring a consistent fit and reliable performance shot after shot. Hunters who already run Invector-DS chokes can add this improved modified option to round out their pattern density options across hunting seasons.
