The Carlson's Sporting Clays Modified Choke Tube for 20 ga Beretta/Benelli 20 gauge systems is engineered from 17-4 stainless steel and precision machined to deliver superior pattern density and consistency. Featuring a 25% larger parallel section, this choke tube throws tighter, more uniform patterns than standard options, helping you hit more targets on the clay range. The knurled end allows for quick, tool-free removal, while the laser-marked constriction at the nose provides instant reference for rapid tube changes during competition or practice. Backed by Carlson's lifetime warranty, this choke tube is designed to be versatile across loads, with compatibility for lead, steel, copper-plated, nickel, hevi-shot shells, and buckshot in sporting clays applications, while cautioning that steel shot larger than BBS should not be used in choke tubes tighter than Full Constriction. Its longer parallel section gives it a performance edge over flush-mount designs, delivering denser patterns ideal for sporting clays, trap, and skeet shooting. Fitment to Beretta/Benelli 20 gauge choke systems makes it a reliable upgrade for shooters seeking consistent, repeatable patterns and a durable, long-lasting accessory for serious field and range use.
