Eh, I can't complain about Gun Mods. But that's just me.
Also, those crazy Dwarves probably knew the Alien Blaster wielding aliens from Fallout 3.
No, wait, that's why they disappeared, they entered the Fallout 3 universe and finished their technological leaps!
What? It's possible.
Jokes aside, the Dwarves probably would make Flintlocks, or at the very least mid 1700 style weapons before they disappeared.
I mean, they did make great technological leaps, the ruins have ballistas and in one case a helicopter.
No, really, in Morrowind, it's obvious the Dwarves had helicopters.
Not A-10 Tank killers, or a Huey, etc, but yeah, that had tech.
