What are the rules for a model having multiple weapons that cause a mortal wound? The wording on KMB seems weird because it says if you roll "one or more unmodified hit rolls of 1, the bearer suffers 1 mortal wound after all of this weapon's attacks have been resolved" (emphasis mine). As far as I am aware there is no way to roll more than one 1 with a KMB, because it's assault 1 and will only fire a second shot if the first result is a 6 (not a 1). Was this just GW adding unnecessary rules, or is it trying to imply that if you have multiple KMB and roll multiple 1s that you'll only take a single mortal wound?

My gut tells me that 4 KMB can cause 4 mortal wounds in a turn, but the wording they chose (one or more) makes me question it.

Probably just for the sake of consistency, which is good. The bigger kustom weapons, the Kustom-Mega Kannon and the Kustom-Mega Zappa have the same wording, but multiple shots.

Essentially you can only get one mortal wound from each weapon, but multiple weapons can zog you multiple times.

So, if you roll 4x for your dread, it takes take 4 MW.
If you roll 4x for your mek gun with KMK, it takes 1 MW.
If you roll 3x for your Morkanaut's zappa and another for its KMB, it takes 2 MW.

Yes, 4 KMB can cause 4 MW max. Its four weapons, and each weapon can only suffer 1 MW, regardless how many unmodified hit rolls of 1 you make. I dont know why the wording is one or more unmodified hit rolls of 1. Maybe there is a way to get more than one shot from each gun, except for dakka dakka ? I dont know, i dont play orks.

Consistency, and it allows them to add more rules later - strat, scenery etc - that alter the number of shots.

Yes, 4 MW from 4 weapons if you have 4 KMB's, since the limit of 1 MW max is for "this weapon" and you have 4 of them.
