does anyone know how to lower the volume of the new sounds?

I am sorry that you are having trouble with them.
To coincide and go well with the sounds that came with the mod, I adjusted the gun sounds to a believable sound level.
When I have enough time, I will lessen the sound levels for you, if you wish, but I am wondering what sounds you had already that made my new gun sounds appear so loud.

I just think the 50s are very high pitch. and was wondering how to lessen the high pitch of it.

Please remember that this sound was recorded, not in a sound studio, but this is still pretty good. I can use my sound editing software (I use GoldWave) to run the sound through and using the built in equalizer, decrease the high pitch sound, or add more bass.
You have tried the sounds in game and think the 50 cal is high pitch?
If I get more of the same opinion from others, I will remake the 50 cal sound and have that for download.
