The Carlsons Delta Set (brand part number 15529) packages close-, mid-, and long-range extended choke tubes for 20-gauge shotguns threaded for the Beretta/Benelli Mobil system. Carlsons machines each tube from 17-4 stainless steel specifically to produce tighter, denser patterns, using a 25 percent longer parallel section than a standard choke. That extra length also reduces pellet deformation and shortens the shot string, which means fewer stray flyers on the pattern’s edge.
