Shotgun Choke Tube: This product is a removable shotgun choke tube designed for the compatible shotgun gauge and thread system identified in the title and specifications. It installs at the muzzle of a compatible shotgun barrel and is used to manage the shot pattern for its intended shooting application.Code Black Turkey is engineered to deliver exceptional consistency, reliable performance, and tight, even patterns with a significantly shortened shot-string. By reducing the overall shot-string length, more pellets reach the target at the same moment—resulting in cleaner, more effective kills at extended turkey-hunting distances. Designed specifically for turkey loads, this tube provides up to 70 yards effective range and produces dense, high-energy patterns. While the pattern on paper may resemble tighter constriction, the combination of our Separating Ring technology and proprietary canoe-porting dramatically shortens the shot-string compared to traditional constriction-only choke tubes. Each Code Black Turkey tube is precision-machined from titanium-infused 17-4 PH stainless steel and finished in a durable bronze titanium coating, ensuring long-term strength, corrosion resistance, and field durability. Important: This tube is NOT safe for use with steel shot.
