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.
Another interesting feature about the weapon is that it was bullpup in design, which means that the magazine is located behind the trigger, and also utilized the blowback system of operation. The bullpup design was a significant tactical advantage because it increased the firearm's compactness and allowed for a smaller, lighter and more efficient firearm.
