Duh! Just another variation of the MG-34/42 and M-60. Cyclic rate is pretty lame compared to the ripping cloth of the -42.
Notice that the belt was not fed from an ammo can.
H&K is overpriced, over hyped, and arrogant as hell to boot!
Not seeing much in the way of "Air Defense" there, But I'd take one in a heart beat. Must be nice to be able to destroy barrels just for a demo.
