Design
The Interdynamics MKR was originally designed using a 4.5×26mm MKR round using solid brass bullets. Its purpose was to provide a flat ballistic trajectory along with armor-piercing capabilities with low recoil for the user to handle, even when fired fully automatically.
It was to use low-cost ammunition. The 4.5×26mm MKR round was claimed to be ballistically as effective at 300 meters as the 5.56×45mm NATO round.
It was a bullpup design, which means that the magazine is located behind the trigger, and utilized the blowback system of operation. The bullpup design made the firearm smaller and lighter.
