The RPK-16 is a further development of the Soviet light machine gun RPK-74. The updated design boasts an interchangeable barrel for close quarter and long-range combat. The 4-kilogram, 5.45-calibre weapon has a rate of fire of 700 rounds per minute. In February 2019, Kalashnikov started limited deliveries of the RPK-16 to the Russian Armed Forces. The weapon is currently in experimental service with the Russian military.
It’s literally just an RPK with modern accessories and a quick-change barrel, and 800m firing range for 7.62×39 is fucking laughable, effective range for that cartridge for accurate fire is about 400m at best, 500-600m for suppression.
