Made from 17-4 stainless and precision machined to produce a choke tube that patterns better than standard choke tubes. These choke tubes feature a 25% longer parallel section in the choke thus throwing more consistent patterns than conventional choke tubes. Each choke tube is knurled on the end to allow for quick and easy removal or installation. Each choke has the constriction lasered on the end for easy reference. Lead shot, Steel Shot, Copperplated Shot, Nickel Shot, Hevi-Shotshells™, and Buck Shot can be used in our Sporting Clay Choke Tubes. Steel shot larger than BB should not be used in any Sporting Clays Choke Tube tighter than Full Constriction. Our Sporting Clays Choke Tubes will throw tighter/denser patterns than Flush Mount Choke Tubes due to a longer parallel section.
