The Interdynamics MKR was an assault rifle concept of the 1980s using a 4.5x26mm Rimfire round using solid brass bullets. Its purpose was to reach high velocity and effective ballistics with low recoil for the user to handle, even in full automatic. The 4.5x26mm MKR round was claimed to be ballistically as effective at 300 meters as the 5.56x45mm NATO round as well as stopping power with the use of a rimfire round supplemented the reliability of the rifle, however the MKR remained in prototype stage.
