M404 Heavy Rifle



The Kaiga 5.56mm M404 Heavy Rifle is a weapon in Deus Ex: Human Revolution.

Background
The Kaiga 5.56mm M404 Heavy Rifle is a 5.56mm multi-barrel heavy machine gun with high rate of fire, employing Gatling-style rotating barrels. This weapon is made by Kaiga Incorporated Ltd, a Russian weapon manufacturing company.

Characteristics
The weapon uses special 5.56x45mm "Flüssig Kühl- Effekt", Liquid Cooling Effect to increase barrels cooling. This minigun is gas-operated like Russian Gatling guns and didn't need electric motor or an external power source. Due to the fact that this minigun does not need an electric motor, the weapon is much lighter but two 5 kg counterweights each are mounted at the rear to better absorb the huge recoil of the weapon. The M404 feature a high capacity cylindrical helical feed magazine hung below the weapon.

The M404 must spin up before shooting, but it offers a higher rate of fire than the other automatic weapons, the FR-27 and TMP-18.
