The Victory Extended Mobilchoke, a competition choke by Beretta, can be used on all Mobilchoke barrels. Made of high quality steel, it features great stress resistance due to heat treatments. It is also subjected to a special coating that guarantees high protection against corrosion. This choke tube is extended by 25mm-0.98" and its 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.These Competition chokes can be used on all Mobilchoke barrels.
