The Carlsons Sporting Clays Choke Tubes for 12 gauge Browning Invector-Plus Skeet are precision machined from 17-4 stainless to deliver tighter, more consistent patterns than standard choke tubes. Featuring a 25% larger parallel section, these chokes produce denser patterns across a wider range of shot sizes, making them a reliable choice for clays, upland, and field shooting alike. Each choke tube is knurled at the end for quick, tool-free removal and has the constriction laser marked on the end for easy reference in the field or at the range. Backed by a lifetime warranty, Carlsons Sporting Clays Choke Tubes are designed to accommodate Lead, Steel, Copper Plated, Nickel, Hevi-Shot, and Buck Shot, with the caveat that steel shot larger than BBS should not be used in choke tubes tighter than Full Constriction. These chokes will generally throw tighter and denser patterns than flush mount options due to their longer parallel section, enhancing uniformity and predictability across multiple shots. Fits all Browning Invector-Plus 12 gauge choke systems, offering a seamless upgrade for dependable performance on the range or in the field.
