That's true. it looks like that's what happened.
I was able to fix the sound level. Had to replace the noise value with the corresponding vanilla gun as well as the crouch sound modifier. Also, some sounds had a start, middle and end identified by _s or _end on the name, which needed the noise level to be set to 0. Otherwise, if all three are set to the vanilla noise volume, each one will generate that amount of noise making it 3 times as loud.
I'll make a reply on one of his mod's and link this forum post! Thanks for the help, guys.
