R9-Arms submachine gun

The R9-Arms submachine gun is a select fire submachine gun chambered in 9×19mm Parabellum. The R9 is notable because some of them are marked "R9-ARMS ", although no such firm exists. It was made for sale to criminal organizations around the world. Unlike most improvised firearms, the R9 is not a copy of an existing weapon design, nor a low quality insurgency weapon such as the Błyskawica submachine gun.
The R9 markings on the gun claim that it is from the United States, but are likely an attempt to gain credibility or baffle local law enforcers.

Speculation as to the gun's origin.
There is much speculation as to where the gun is being produced, if it is still being produced. The most plausible theory is that they were produced in Croatia, due to the number of R9-Arms submachine guns confiscated there. Furthermore, Croatia is and has been the home of a number of illegal arms manufacturers, such as Mirko Vugrek and his son, Ivan Vugrek.
