The bodyguard of North Korean dictator Kim Jong-un have been photographed with enormous helical magazines on their AK rifles. The round capacity could be anywhere between 75-150 rounds. I cannot identify the rifles. They are probably North Korea’s domestically produced Type 88, Type 98 or Type 98-1.
I wonder how that works. Most guns which use helical mags are chambered in pistol calibers rather than rifle calibers as seen above.
