im level 13 14 or 15 and ive only came across 1 minigun and it was completlydestroyed and i cant find any ppl who sell them ive checked crimson gun runners 188 trading post bos plz help

black mountain. the super mutes have em. If you start from neils shack you can make it a quest.

i went through there and only found incinerators and marksman carbines

me too, the first time i went there. but when i fast traveled there i was swarmed by them and thats about all i got. a couple flamers etc, but i got at least 3 miniguns

go get the unique one.

Kill the Chukapara with automatic weapon (lol).

If you have Wild Wasteland you can try your luck at the Big One as well.

Or even dump it in near by Mojave Express Post box.

The NCR dude in the Mojave Outpost does repair to 100%, so even if you find only one you can get it back up and running, if you've enough caps.
If the NCR hate you, just put on a uniform before going there, then they regard you as neutral - just don't change until you've left the area

Just make weapon repair kits, the stuff to make them is plentiful and it's cheaper than getting it repaired at a merchant.

This, and you can steal your caps back from him (it takes a while, save before trying).

He's also a great way to make money. Go kill/loot/pillage, take your stuff to him to repair, steal you caps back, go sell your now 100% stuff for a huge profit.

I have 4 almost perfect condition miniguns by now... and the special one. Got a few at black mountain, and 2 or 3 from Novac. The Super Mutant that's cloaked that kills the farmer Brahim... he kept respawning now and then, killed him 2 or 3 times and he always has a minigun on him.
