Is this a gun?

I just again looked at the 9 minute Al Jazeera Mavi Marmara video and saw something I never noticed before:



Doesn't that look like a gun that the IHH is firing at the helicopter? Or is it something else - a camera, a mic?

UPDATE: The LGFers pretty much all think it is a camera. I'm intrigued by the possibility that it was one of the initial kidnapped IDF officer paintball guns.
