HEVI-Shot 560124: Hevi-Shot does not only provide top-tier ammunition but also offers premier chokes tailored for your specific hunting needs. Gun specific styles are available for most gun models. These chokes, made from aircraft-grade 17-4 stainless steel, employ the use of the latest patterning equipment to ensure the optimal constriction based on gun type and achieve the best possible pattern. Each Hevi-Choke features a knurled fore-end that can be hand-tightened, allowing for effortless field replacements. The 12-gauge Waterfowl choke tube on offer here is an extended-range model, perfect for distances beyond 35-yards, and is ported. It is compatible with models such as the 31 Extrema, Tekny\'s, Silver Pigeon II, and Silver Pigeon III shotguns.
