I use it all the time when using the minigun.
I was using it last night with the minigun too(Security tower(pretty sure that's the name), Security side where you have to defend the safe from being hacked, peaking in and out of the glass doorways), pretty awesome.
I knew about it the whole time, just never used it because I like to move and shoot.
