N18 Weapons with shock and rapid fire question

[OrderForm]

The Heavy Blaster has shock and rapid fire (2). Does this mean that all the results of the rapid fire dice automatically hit on a six?

 

[TopsyKretts]

I would assume a hit that includes a 6 would trigger auto-wound on all yes. Rapid Fire is all or nothing and when combined shock piggybacks on top of that. But I think you're wrong about a 6 auto-hits. Because some shots require more than 6+, for example 7+ (improbable shots). Shock pressumably requires the first roll to be 6+ for Improbable Shots to trigger the auto-wound?
