A BH will want the Ion Blaster.
If you're doing Armstech, you'll some rifle/pistol schematics that come with Aim and some that come with Cunning. Pistols with Aim are for Bounty Hunters, rifles with Aim are for Vanguards, pistols with Cunning are for Smugglers, rifles with Cunning are for Operatives. (Some tanking companions, such as Kaliyo and Corso, can use either pistols or rifles with Aim.)
Is it because of the Aim?
