The LM-54 Chord is a common rarity weapon in Crossout.
Weapon can be manufactured from the Engineers Common workbench upon reaching level 1 with that faction. Its production time is 5 seconds.
This weapon cannot be fused due to its rarity, which is white (Common).
The LM-54 is a light machine gun mounted to a turret frame. The gun itself looks to be a Logicer LMG with a large cooling sleeve. A wooden handle at the back of the gun presumably allows operators to aim manually. A motor with a rebar axle holds the gun in place and allows elevation control, this motor is held to the azimuth drive by thin rusted plates. An ammo box with a large belt plugs from the side of the mount into the actual firing chamber, allowing large amounts of ammo to be fired without reload (even if the reload doesn't actually exist in game).
The base of the weapon is made of a collection of curved metal plates impaled and held together by rebar and jittered placement of bolts.
