I don't own the rifle so I'm mostly speculating, but when doing some research on the SR25 platform myself I came across this comparison of the different gearboxes.
SR-25 Guide, The one and only guide you need for all airsoft SR-25.
From what this says/shows it looks like the ares pretty much has a standard V2 other than maybe where the hop attaches. Remember this is largely speculation, but it looks like you could get the p* gearbox to work with minimal trouble The Prowin hopup might not be an option tho.
