Built for Winchester 20-gauge shotguns, this Carlson Bone Collector turkey choke delivers the extended constriction geometry serious turkey hunters rely on for dense, consistent pellet placement downrange. The .565 constriction is purpose-engineered to pattern tight across the full range of modern turkey loads—from traditional lead shot to advanced alternatives like tungsten and TSS—giving you the flexibility to dial in your exact setup. Precision-machined from 17-4 heat-treated stainless steel and finished in a non-reflective matte black, this tube resists corrosion while staying invisible to game. Pattern testing with your specific ammunition before heading afield ensures you know exactly where your shot will land when it matters most.
