Carlson’s Delta Waterfowl Extended Mid and Long Range 20 Gauge Choke Tubes are precision-engineered from 1704 stainless steel to deliver tighter, denser shot patterns compared to standard choke tubes. The extended design features a 25% longer parallel section that produces more consistent patterns downrange. Each tube is knurled at the end for quick removal and carries laser-marked constriction and size designations on both the end and body for straightforward identification.
Steel shot performs exceptionally well through these choke tubes. Do not shoot steel shot larger than BB or any steel load faster than 1550 FPS through the Long Range constriction; loads exceeding this size and velocity should be paired with the Mid Range choke tube instead. The 2-pack is backed by Carlson’s lifetime warranty.
This choke tube set fits Winchester Browning Invector, Mossberg 500, Weatherby Pre 1993, and Ruger Red Label shotguns. Winchester SX-2, SX-3, and SXP models require Browning Invector Plus tubes.
