The Carlson Cremator Ported Choke 12 ga. Remington LR represents Carlsons precision engineering with Triple Shot Technology (TST), featuring three graduated rings in the choke taper that create a more gradual transition from bore to constriction for reduced pellet deformation, fewer flyers, and denser patterns, making it exceptionally effective on waterfowl throughout the season. The Cremator series imposes no size or speed restrictions with steel shot across its three constrictions, while adding the advantages of an extended choke tube that delivers a 25% longer parallel section for tighter, more consistent patterns, plus wrench-less installation, quick removal, and muzzle protection. Available in ported or non-ported configurations and manufactured in the United States from heat-treated 17-4 stainless steel, these chokes carry Carlsons lifetime warranty and are designed for enduring accuracy. Note that Optima HP and Remington Pro Bore Long Range cannot be used with any steel shot larger than #2, a detail to consider when selecting the appropriate constriction for your preferred load.
