The Carlsons ported Modified choke tube (brand part number 18895) is a 12-gauge, extended choke built for the Browning Invector Plus system with a .720-inch Modified constriction. Made by Carlsons Choke Tubes from precision-machined 17-4 stainless steel, this choke carries a 25% longer parallel section than a conventional choke tube for tighter, more consistent patterns, finished in blued steel. Vent ports cut into the extended tube help bleed off gas to reduce felt recoil and muzzle jump between shots. It handles lead, copper-plated, nickel, Hevi-Shot, bismuth, and tungsten shot, though steel shot should stay at BB or smaller and under 1550 fps.
