Carlsons Delta Waterfowl Extended Mid-Range Choke Tube 20 Gauge

Carlsons Delta Waterfowl Extended Mid-Range Choke Tube for 20 Gauge is designed for shooting situations at 25 to 40 yards. Carlsons’ steel shot choke tubes are engineered to pattern steel shot with excellent results. The extended design features a longer parallel section that reduces flyers and produces denser patterns. These tubes extend 3/4″ outside the barrel, protecting your barrel from damage caused by prolonged steel shot use. The longer parallel section enables the use of larger steel shot in tighter choke constrictions. Constructed from 17-4 stainless steel with a knurled extension and blue finish, each tube is backed by a lifetime warranty. All steel shot sizes may be used in the close and mid-range choke tubes. Do not use steel faster than 1550 FPS or steel shot sizes larger than BB through the Long Range choke tube. Fits Winchester Browning Invector, Mossberg 500, Weatherby Pre 1993, and Ruger Red Label. Winchester SX-2, SX-3, and SXP use Browning Invector Plus tubes.
