The Carlsons Cremator Ported Choke Tube 20 ga. Winchester MR, LR 2 pk. delivers Carlsons signature Cremator performance with Triple Shot Technology (TST), featuring three graduated rings in the taper that create a gradual transition from bore to constriction for reduced pellet deformation, fewer flyers, and denser, more uniform patterns ideal for waterfowl across the season. The Cremator Series offers no size or speed restrictions with steel shot in any constriction, while adding the benefits of an extended choke tube, including a 25% longer parallel section for tighter, more consistent patterns, and wrench-less installation for quick, tool-free removal and muzzle protection. Available in both ported and non-ported configurations, these tubes are precision-machined from heat-treated 17-4 stainless steel in the United States and carry a lifetime warranty, ensuring durable performance in demanding field conditions. The design fits popular platforms such as Winchester, Browning Invector, Mossberg, Weatherby, pre-1993 models, Ruger Red Label, and Winchester SX-2/SX-3 & SXP when using Browning Invector Plus tubes, providing versatile compatibility for versatile waterfowl setups.
