Dude, even I made it to the nexus hotfiles back in the skyrim days. It was a ported TW2 mage robe, all I had to do was fix some shit in nifskope
I honestly don't understand why some people like some mods that much
It was a female CBBE mod, of course
Yes, exactly, I was wrong
but still, it's a weapon that relies more on DMG/s rather than shooting heavy calibers
real miniguns shoot .30 so I guess the 5mm rounds are similar.
Wait, I'll give you some links then!

Loads of Ammo (this adds a few extra mods to some rifles, it's not what you wanted but you can switch the calibers to some, adding FMJ rounds, armor incendiary piercing rounds, etc
also new under barrel mods like flamethrowers and granade launchers, very fun mod)

Gee, will this be enough? And these are only the ones I like. I also hate the lack of heavy weaponry this game offers.
