You might be missing some information. Expose only increase the primary weapon firepower. The only thing that increases autoblaster is Kavil for out of arc shots.
Kavil + Veteran Instincts + Autoblaster Turret + Unhinged Astromech + Engine Upgrade is a lot of fun.
You gave me a thought:
Kavil + Expose + Autoblaster turret + Unhinged + Experimental Interface.
You get 4 autoblaster dice plus a focus or TL from your first action. You would only use it if you aren't in danger of getting ripped apart that round, but the 1 defense die is nigh useless anyway. Alternatively, take Expert Handling for better positioning + survivability. Unhinged droid still helps drop the stress.
We cleared this up like 2 posts after mine.
