Carlsons Delta Waterfowl extended choke tubes are supplied as a two-piece set for Beretta/Benelli MobilChoke systems in 20 Gauge. They are engineered to yield tighter, denser patterns than conventional choke tubes by using an extended parallel section. Each tube is knurled at the end for easy removal and is laser marked with its constriction and size on both the end and body. The tubes are compatible with steel shot when used within the stated size and velocity limits.
