Description
The Carlsons Cremator Ported Choke Tube is a long-range, extended choke designed for 12 Gauge shotguns using the Winchester/Browning Invector thread pattern. It incorporates Carlson’s Triple Shot Technology (TST), a series of three graduated rings in the taper section that promotes a gradual transition to the final constriction for denser patterns and reduced pellet deformation. The tube is made from heat-treated 17-4 stainless steel with a matte-black finish and is offered in a ported configuration to help manage recoil and muzzle rise.
