The ECR-21 is a good weapon, with respectable power and good accuracy, but it's not good for CQC and Full-Auto, due to it overheating problem, resulting in the famous cook-off (The act of exploding a gunpowder cartridge before you pull the trigger, resulting in huge loss of accuracy and firepower). However all this is solved in ECR-21A2, making it better than the original ECR.
