The HEVI-Shot Hevi-Choke Waterfowl (brand part number 85631) is engineered specifically to get the most pattern performance out of HEVI-Shot ammunition, built for 12 gauge shotguns running the Browning Invector-DS thread pattern. Machined from aircraft-quality 17-4 stainless steel, it’s developed using state-of-the-art patterning equipment to dial in the optimum constriction for each gun-specific application. The extended, ported profile helps tame recoil and muzzle jump, and a knurled fore-end lets you hand-tighten the choke for quick, tool-free changes in a duck blind or field.
