If the gun runs off of AA batteries (and 250 fps with .12), chances are it takes proprietary mags. When buyairsoft have parts for their guns they usually list in the sale such as "buy an extra rail, mag, etc for this gun" in the listing. They have every accessory listed except mags. So my guess is you're SOL and won't find any mags that will fit it. You can try, but chances are pretty good that you'll have extra mags you can't use.
Not to shit on you here, but at under 180 fps with .2g (the lowest weight you should use), this gun really is garbage. You would have been better off with the clear junk they sell at Canadian Tire over this thing.
