Iver Johnson Choke Tube Features The Iver Johnson Choke Tube is machined in a true skeet constriction opening the shot pattern early so shooters have maximum coverage on the close fast-moving targets found on a skeet range. Built from stainless steel the tube resists corrosion and wear from repeated cycling and exposure to powder residue and weather. Its extended profile sits just proud of the muzzle making it easy to identify and remove compared to a flush-mounted tube. The Mobil choke style threading matches the pattern used on many Beretta and Benelli pattern shotguns giving shooters a direct factory-style fit. Because this tube uses the widely adopted Mobil thread pattern it is a straightforward upgrade or replacement for shooters who already own a compatible 12 gauge shotgun. The stainless steel construction is built to hold up under the high round counts typical of competitive skeet shooting. Its skeet-specific constriction makes it a dedicated choice for shooters who want a tube optimized for one discipline rather than a general-purpose option. Clay target shooters looking to fine-tune pattern performance for skeet will appreciate having a purpose-built tube in their choke selection.
