The Chain Links on the ammo are very sturdy allowing them to be reused.

The trigger has two actions, single action and full auto, the single action was used to simulate a single rifle. This tactic was used to draw the enemy into the field of fire, while the thought it was just one rifleman.

This guy like the M60 has a distinctive sound. The MG 34 makes a spraying sound and upon letting up of the trigger it makes a shhhhhuck metallic clacking noise.

The M60 makes that same sort of noise, but its initial fireing sound is a deep shooooook. Firing it prolonged it sounds much like a chinook starting its rotation.
