The Carlson's Cremator Waterfowl Long Range Ported Choke Tube for 20 ga Benelli Crio/Crio Plus .592 delivers precision performance with Carlsons Triple Shot Technology, featuring three graduated rings in the taper to create a gradual bore-to-constriction transition that reduces pellet deformation and flyers for consistently dense patterns on waterfowl throughout the season. This Cremator series has no size or speed restrictions with steel shot across its three constrictions, and it includes the benefits of an extended choke tube with a 25% longer parallel section for tighter, more uniform hits, all while offering both ported and non-ported configurations to suit your preferred recoil management and muzzle protection. Built in the USA from heat-treated 17-4 stainless steel, these chokes are precision-machined for lasting performance and come with Carlsons lifetime warranty, ensuring reliable field usage. The design supports quick, wrench-less installation and easy removal, helping you adapt to changing field conditions without sacrificing pattern density. Note that Optima HP and Remington Pro Bore Long Range models cannot be used with steel shot larger than #2, making this Cremator choke an ideal choice for waterfowl hunters seeking enhanced long-range performance with compatible ammunition.
