The Carlson Cremator Choke Tubes, built in the United States, bring the brands Crane Shot Technology to your 12 gauge with a Winchester 2-pack that covers close, mid, and long-range constrictions for versatile hunting and target shooting. Carlsons innovative Triple Shot Technology features three graduated rings in the taper that create a smoother transition from bore to final constriction, reducing pellet deformation and flyers for denser, more uniform patterns across the field. The Cremator series delivers no size or speed restrictions with steel shot in any constriction, while extending the choke tubes parallel section by 25 percent for tighter, more dense patterns and a wrench-less installation that eases quick removal and muzzle protection. Choose between ported or non-ported configurations to suit noise and recoil preferences, all precision-machined from heat-treated 17-4 stainless steel to endure field use. These tubes carry a lifetime warranty and are designed for reliable performance on all waterfowl throughout the season. Note: Optima HP and Remington Pro Bore Long Range cannot be used with any steel shot larger than #2.
