After-Burst, as per other augmentations, is an add-on to a frame already designed, so the entry lists limiations/requirements as to what kind of a frame you can assign the aug to.
As far as I can see, there is no other limitations in the rules or the errata other than that the weapon may not have indirect fire capability (tho I suppose one might want to interpret this as a stipulation against using the aug in conjuction with indirect fire specifically). So while it can be pretty much anything otherwise available, really, you can't use this augmentation to create an indirect fire anti-vehicle weapon (as per rules, phase weapons do have indirect targeting capability but they aren't counted as IF weapons per se).
