No, the mounting mechanism is designed to fit the AD200 (Pro).
I didn't realise that, as it is advertised specifically for the AD200 ("eVOLV 200" with Adorama's branding).
I'm not super excited about such a simple rectangular->round adapter because there is no respective light reshaping (unless you use the dome). For most accessories such as gels, grids, etc. it doesn't matter whether the head is rectangular or round. The only real advantage I see for a round accessory is that the bounce scoop can easily rotate. When you are using an equivalent accessory on a rectangular head, adjusting is not quite as easy, unless the accessory adds a rotating mechanism.
Not sure what you read but here's the text taken directly from the link...
***Take advantage of the Flashpoint S-R1 Adapter and AK-R1 Accessory Kit, which allows you to attach quickly and easily Flashpoint eVOLV 200 round head modifiers to your Flashpoint Zoom and Zoom Li-on speedlights. By mechanically clamping to your flash, the included Flashpoint S-R1 Accessory Adapter provides a round platform for instantly snapping on included magnetic modifiers. This gives you a fast change of light pattern between one scene to the next. Among the round head accessories shipping in the kit are a four-leaf barndoor, diffusion dome, a 30° honeycomb grid, a wide-angle diffuser, six color filters, two filter holders, a spot lightsnoot, and a requisite Bounce Scoop.
