Is that the bottom of the magazine below the strap? If so, then it is proof postive that it is faked since the part of the magazine above the strap is missing and the bottom part just floats there.

It looks to me like the magazine is light gray with ribs on it with a black mag extender attached on the bottom.

However, even when I zoomed in, I couldn't tell for sure if it was a gray magazine or just the light blue shirt of the guy in the background.

However, if would be hard to paste in the guy and not paste in part of the magazine in the process, so I think that it's likely just a gray magazine with a black extender on the bottom.
