The KS-23 is a Russian shotgun although because it uses a rifled barrel it is officially designated by the Russian military as a carbine. KS stands for Karabin Spetsialniy Special Carbine. It is renowned for its large caliber firing a 23 mm round equating to 6.27 gauge using the American standard of shotgun gauges and approximately 4 gauge using the current European standards (based on the metric ‘CIP’ tables) making it the most powerful shotgun in use today.
