The first thing I've noticed about the scorpion is that the amount of slots it takes to carry is much bigger than it's actual size. These are my pictures to compare. As you can see the scorpion takes up the same amount of space as the ak74u, but is only about 1/3 the size. That being said it should only take 4 slots instead of 12. Also, it can also be said that the scorpion is inferior to the rak because the magazine size is small, but if the scorpion would cost less inv. space, then it would actually be more efficient to carry.
