Built specifically for serious turkey hunters, the Carlson Bone Collector Remington Pro Bore choke tube delivers the tight, consistent patterns needed for clean, ethical harvests. This .665 constriction is engineered to work reliably across the full spectrum of modern turkey loads—including lead, bismuth, tungsten, and TSS ammunition—so you're not locked into a single shot type. The extended parallel section minimizes flyers and concentrates pellets downrange where they count, while the precision-machined 17-4 stainless steel body and matte black finish resist corrosion in the field. Pattern testing before your hunt with your exact ammunition choice is essential, as different loads and manufacturers will perform differently through any choke tube. Fits Remington Pro Bore shotguns; measure your barrel before ordering to confirm compatibility.
