The Carlsons Cremator Ported Choke 12 ga. Winchester LR from Carlson delivers precision performance with our brand new Triple Shot Technology (TST), featuring three graduated rings in the taper section to create a smoother transition from bore to constriction for reduced pellet deformation, fewer flyers, and denser patterns that excel on waterfowl across the season. This Cremator design imposes no size or speed restrictions with steel shot in any of the three constrictions, while simultaneously offering all the benefits of an extended choke tube, including a 25% longer parallel section for tighter, more consistent patterns, wrench-less installation for quick removal, and muzzle protection. It is available in ported or non-ported configurations and is precision-machined from heat-treated 17-4 stainless steel in the United States, ensuring durability and a lifetime of reliability. Note that Optima HP and Remington Pro Bore Long Range cannot be used with any steel shot larger than #2. The Cremator line is designed to fit Winchester, Browning Invector, Mossberg 500, Weatherby pre-1993, Ruger Red Label, and Winchester SX-2/SX-3 & SXP models, providing versatile performance across a broad range of popular setups.
