NOTE:  Winchester SX-2 & SX-3 use the Browning Invector Plus choke tubes

Waterfowl Extended Choke Tubes manufactured from 1704 stainless steel and designed to throw tighter and denser patterns than conventional choke tubes. These choke tubes feature a 25% longer parallel section in the choke, thus throwing more consistent patterns.

2-Pack consists of one Mid Range, one Long Range Super Steel Waterfowl Choke, and one choke tube wrench.

Steel shot may be used with exceptional results. Do not shoot steel shot larger than BB or any steel load faster than 1550 FPS through the Long Range Constriction.  Loads that exceed this size and speed should be used with the Mid Range choke tube.

Each choke tube is knurled on the end to allow for quick and easy removal.  Constriction and size are laser marked on the end and body for easy reference.
