Airsoft Information Question?

I just bought the UTG MK96 Sniper Rifle package and I was wondering what gram BBs I should use with it. I think since it's a sniper rifle and its meant to shoot long distances that it should have slightly larger BBs than that used in AEGs right? I use .2 gram BBs in my Jing Gong AK-47 so would those work in the MK96?
