Built for serious turkey hunters, this Carlson Bone Collector choke tube delivers the tight, consistent patterns needed to put more pellets downrange where they count. Engineered specifically for 12-gauge Beretta Optima HP shotguns, the extended .680 constriction is optimized for shot sizes #4 through #10, handling everything from traditional lead to modern alternatives like bismuth, Hevi-Shot, and TSS loads. Precision-machined from heat-treated stainless steel with a non-reflective matte black finish, this tube combines durability with a refined, extended taper design that minimizes flyers and maximizes on-target performance. Before your first hunt, pattern your specific ammunition through this tube to verify its fit with your chosen shells—different loads will perform differently from the same choke. Ships ready to install on compatible Beretta models.
