The MA-0K02 was the second version from the Micro-Abrasion series. It took less time to cool than it's predecessor, though the barrel would explode after extended use of the weapon. This would often critically injure, or kill, the weapon's carrier. The weapon was discontinued soon after production began. A year later, the MA-0K03 was released.


The weapon was the same size as its predecessor, but the weapon used a thinner metal to make it lighter. The weapon was made to use both incendiary and normal, armor piercing rounds, but this caused the barrel to expanded which would result in the gun exploding after extended use.
