Avian-X Waterfowl Crusher Choke Tube Features The Avian-X Waterfowl Crusher twin pack gives the waterfowl hunter both a Light Modified and a Heavy Modified choke tube covering a wider range of shot distances and calling scenarios than a single constriction can handle. Built from steel and cut to the widely used Rem Choke pattern the tubes drop into any shotgun threaded for that standard without additional fitting. The gold-colored PVD finish is both functional and stylish resisting corrosion from repeated exposure to wet marsh and field conditions. Having two constrictions on hand lets a hunter adapt quickly as birds work closer or hang up at distance. Swapping between the Light Modified and Heavy Modified tubes takes only a moment in the field letting the hunter tailor pattern density to the specific shot presented rather than compromising with one all-purpose choke. The durable steel construction stands up to the rigors of a full waterfowl season without losing its finish or function. Because the tubes share the Rem Choke thread pattern they fit a wide range of popular waterfowl shotguns already in a hunter s lineup. The Avian-X Waterfowl Crusher twin pack is a practical adaptable addition to any serious waterfowl hunter s gear bag.
