Replaces the firing and reloading sounds of the HK 51B with those of the HK 21 from CoD: Black Ops. Okay so this one comes from the same DLC as the Scout and it has similar damned problems with its reloading sounds, where some sounds that shouldn't be used interchangeably are used interchangeably.

Added versions for the Brenner 21 and the Gewehr 3. They have suppressed firing sounds but no reloading.
