Carlson Cremator Waterfowl Long Range Ported Choke 20ga Browning Invector .597

The Carlson's Cremator Waterfowl Long Range Ported Choke Tube for 20 ga Browning Invector Plus .597 delivers advanced long-range performance with Carlson's brand-new Triple Shot Technology (TST), featuring three graduated rings in the taper that create a smoother transition from bore to constriction for reduced pellet deformation, fewer flyers, and denser, more uniform patterns—ideal for waterfowl season success. This Cremator line imposes no size or speed restrictions with steel shot in any of the three constrictions, while offering the benefits of an extended choke tube, including a 25% longer parallel section for tighter, more consistent patterns, plus wrench-less installation, quick removal, and enhanced muzzle protection. Available in ported or non-ported configurations, these tubes are precision-machined from heat-treated 17-4 stainless steel in the U.S.A. and carry a lifetime warranty, underscoring durability and reliability in demanding field conditions. Note: Optima HP and Remington Pro Bore Long Range cannot be used with steel shot larger than #2. This choke tube is designed to maximize dense, effective patterns on a wide range of waterfowl species throughout the season.
