The Carlson’s Browning Invector Plus Choke Tube in Modified constriction is engineered as a replacement for 12-gauge Browning shotguns used in Sporting Clay applications. This choke tube features Modified constriction with a .720″ diameter and is constructed from 17-4 heat-treated stainless steel in a flush-style design.
Built from 17-4 stainless steel and precision machined for improved patterning performance, this choke tube incorporates a 25% larger parallel section that produces more consistent patterns compared to conventional designs. The knurled end enables quick choke changes when needed. The tube is compatible with Lead, Copperplated, Nickel Hevi-Shot, Bismuth, Tungsten, or Steel Shot ammunition.
Carlson’s manufactures every choke tube in the United States and backs each one with a manufacturer’s lifetime warranty. For best results, pattern your choke tube with the specific shotshell load you will be using in the field.
