Carlsons 07777 Delta Waterfowl Retay 12 Gauge Long Range 17-4 Stainless Steel Black

These choke tubes feature a longer parallel section allowing for fewer flyers and denser patterns. These choke tubes extend 3/4 outside the barrel eliminating damage to your barrel caused by prolonged steel shot use. The longer parallel section allows for use of larger steel shot in tighter choke constrictions. They are made of 17-4 stainless with a knurled extension and a blue finish. Do not use steel faster than 1550 FPS or steel shot sizes larger than BB through the Long Range choke tube.
