Cyberpunk Medium Machine Gun

Ok this thing is stupidly heavy. It was meant to be a Light MG but I think it's too big. Lemmie tell ya why!

 

The stock is huge, the gun uses 75 round belts stored in boxes, of which 2 are kept in the stock. When one is empty, open the hatch, remove the empty one, slide the full one forward and replace the old one.

 

The second reason it's so heavy is that the barrel is cooled by controlled amounts of liquid nitrogen pumped through very small holes in the barrel.

The tank in front of the trigger is the nitrogen tank, it's insulated. What appears to be a gas tube is actually the nitrogen return tube.

 

The tank has two holds, the main hold is used for circulating nitrogen, the second is for re-cooling the nitrogen (with more nitrogen).

If the nitrogen is re-cooled so much that the cooling hold becomes the same temperature as the circulating hold, they are combined in the effort to increase the area of the "liquid" heatsink.

(Same concept that a Full tower uses vs a Mid tower for airflow, More air = better heat dispersion.)
