Russian arms manufacturer Kalashnikov, founded in 1807, supplied weapons to Russia's imperial tsars and still equips the Russian army today.
Though it is most famous for the AK-47 rifle, the company - whose full name is Kalashnikov Concern - has expanded into a global arms manufacturer for 27 countries.
But some of their latest prototypes appear downright bizarre and have been widely mocked by experts.
There is no hard evidence to suggest that these prototypes are in use yet or fit for purpose. Leonid Bershidsky, a Bloomberg opinion writer, said most Kalashnikov prototypes are just for show.
Take a look at 15 of the company's bizarre new prototypes below - from personal aircrafts to desert buggies with machine guns mounted on top.
