Carlsons Bone Collector Invector Plus 20 Gauge Shotgun Choke

Carlson’s Ported Bone Collector Turkey Choke Tubes deliver a super tight, pattern-tested constriction designed to throw extremely tight patterns with all shotshell ammunition loaded for turkey hunting, including lead, nickel-plated, copperplated, bismuth, hevi-shot, tungsten, and TSS. The extended taper section leading to the constriction ensures tight patterns with fewer flyers, resulting in more pellets on target with every shot. These Invector Plus chokes for Browning 20 gauge shotguns are precision-machined from 17-4 heat-treated stainless steel and finished in non-reflective matte black. Each constriction has been pattern-tested and delivers the best patterns with #4 through #10 shot. For shot sizes larger than #4, a more open choke tube will provide optimum patterning. Remember to pattern your shotgun with the specific shotshell load you intend to use, as different ammunition types and manufacturers will produce different patterns from the same choke tube.
