  • One side of the weapon model has high quality textures whereas the other side is low quality.
  • The word "Hecker & Koch GmbH", "Made in Germany", "Heckler & Koch Defense Inc." and "Sterling VA" can be seen on the weapon. The word "Sterling VA" would refer to Sterling, Virginia which is the location of Heckler & Koch Defense Inc.'s HQ is situated.
  • This weapon was a skin for the M4A1 before it was officially released as a standalone weapon.
  • When firing the weapon, a bullet model can be seen clearly when the chamber ejects the bullet. But weirdly, when firing the last round the bullet is still attached in there instead of going out. This also happens to its counterpart, the AKM.
  • Before the Free Update patch, this weapon used to have a level restriction. The players must achieve the required level (depending on each region) or higher to purchase it.
