Normally the MM-1’s are 40mm but apparently there were some in 37mm, possibly for riot control purposes. Although it does look like a modern design, it’s based on a much older rotating launcher. The intimidating appearance of the MM-1 has probably lead to more roles in Hollywood movies than actual service issue with police departments or military forces. (GRH)
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.
