Beretta OEM chokes are made to the same high standards as your Beretta shotgun. Great care is taken in machining these chokes to match Beretta shotguns perfectly, with the highest possible concentricity and a smooth finish. Color-coded knurled ends and corrosion resistant coatings set Beretta Victory chokes apart from the rest. These Competition chokes can be used on all Mobilchoke barrels. Made of high-quality steel, they are of great stress resistance due to heat treatments. They are subjected to a special coating that guarantees high protection to corrosion. They are extended by 25mm-.98 and their external shape has been studied in order to guarantee installation and de-installation without specific tools. The end of the choke is identified by a colored alloy stripe for fast and easy indication of the constriction.
