The Carlson's Sporting Clays Improved Cylinder Choke Tube for 20 ga Beretta/Benelli .615 delivers tighter, more consistent patterns thanks to 17-4 stainless construction and precision machining, with a 25% larger parallel section that outperforms standard choke tubes. This design means shooters can achieve denser, more uniform patterns across a range of target presentations, making it ideal for sporting clays, trap, and field shooting where consistent performance matters. The knurled end allows quick, easy removal between stations, while the laser-marked constriction on the end provides immediate reference for optimal choke selection in variable field conditions. Backed by a lifetime warranty, Carlson's Sporting Clays Choke Tubes are built to endure the rigors of regular use, and they are compatible with lead, steel, copper-plated, nickel, Hevi-Shot, and buckshot within sporting clays guidelines, with the caveat that steel shot larger than BBS should not be used in any choke tighter than Full. Fitment to Beretta/Benelli 20 gauge choke systems ensures a secure, reliable upgrade for improved performance on game or clay ranges.
