Yeah - I think the Autocannon with the Munitions Pack synergy upgrade describes what you want to go for pretty closely. Again, you can flavour the specifics how you please since there's lots of different autocannon models and what's presented is more an umbrella term describing the general idea.

Yeah I'm just really picky about this because an autocannon that fires at 80 RPM is a lot different from one that fires at 200+ RPM
