I just uploaded V2 of this file. It changes the spin-up/spin-down sounds and adds a bit of an echo after firing. I plan on doing a toned down version as well just in case anyone finds the current sounds to be too loud.

This is one of the sounds from my personal sound mod that I've never released. I'm just now getting around to pulling my files from my old hard-drive and converting them over to FO4. Give it a go (in game) and I'm willing to bet that you will like it.
