The Carlsons Cremator Ported Choke 12 gauge for Remington MR combines Carlsons brand-new Triple Shot Technology with close, mid, and long-range constrictions to deliver a smoother transition from bore to final choke and produce denser patterns with fewer flyers, thanks to three graduated rings in the taper that reduce pellet deformation. This design, paired with an extended 25% longer parallel section, yields tighter, more uniform patterns across the seasons waterfowl ranges while offering the practical benefits of an extended choke tube, including faster wrench-less installation, quick removal, and enhanced muzzle protection. Available in ported or non-ported configurations, the Cremator Series is constructed in the United States from precise, heat-treated 17-4 stainless steel and carries a lifetime warranty, ensuring rugged performance in field use. The system imposes no size or speed restrictions with steel in any of the three constrictions, making it a versatile choice for varied hunt conditions, and it is specifically noted that Optima HP and Remington Pro Bore Long Range cannot be used with steel shot larger than #2.
