This was the May 30th 2021 remake of the old 2014 ref of the Borz "Derelict" variant.

The 'Borz' was an Armenian/Chechen improvised submachine-gun that saw action during the First and Second Chechen War, in the 1990's. While there are other variants of the Borz, like the K6-92, this variant is likely to have been made before or after the K6-92. This variant uses a 9mm caliber with 9x18mm Makarov ammunition. Rate of fire reaches as high as 1000-1200 rounds per minute, maximum range of this weapon is between 50 and 70 meters. Magazine can carry around 20, 25 or 30 rounds at a time.

In the RP universe, this weapon was adopted by the Mettaurian Federation, and had been modified and improved for better stability. Rate of Fire had been reduced to 900 RPM, and magazine carries only up to 25 rounds. While the weapon did not seem satisfactory to the Mettaurian Army, it became a gangland favorite.
