Essentially a box that bullets come out of, the MAC-10 SMG boasts a high rate of fire, with poor spread accuracy and high recoil as trade-offs.
It has been chromed then overlayed with a semi transparent hydrographic pattern of nuclear skulls and bones.

This skin is available in wear conditions from 0% (Factory New) to 70% (Battle-Scarred).
The values were set by the game development.
