Steel shot choke tubes pattern steel shot extremely well. These choke tubes feature a longer parallel section allowing for less 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. 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.
