Smart firing platforms are basically a stationary drone (but without the Rigger Interface, which means no Jumping In). They have Pilot 3, Targeting Autosoft 3, can be upgraded with additional Autosofts (which would include Smartsoft). The basic write-up on Core pg 433 doesn't say anything about benefitting from the Smartgun bonuses on their own, but does specifically call out that someone controlling them remotely can benefit if they have an implanted Smartlink.
Which again, makes no sense in my mind. Since Smartlink is an Eyeware function, which has zero relevance inside VR.
