The Carlson’s Choke Tubes Ported Buckshot Choke (brand part number 18899) threads into the Invector Plus pattern found on Browning 12 gauge shotguns and is purpose-built to tighten downrange patterns with 00 and 000 buckshot. Carlson’s cuts a ported design into the tube to bleed gas and cut the recoil and muzzle jump that come with heavy buckshot loads, a real benefit for a home-defense or law enforcement shotgun that needs to stay on target through multiple rounds. The constriction is engineered to optimize patterns across both large and small buckshot loads rather than favoring one, and the tube extends about an inch past the muzzle. Machined from 17-4 heat-treated stainless steel, it’s built to run lead, steel, or Hevi-Shot loads within the manufacturer’s steel shot limits.
