I think the mag is just behind the forward hand grip. It is the black thing partially obscuring the blue t-shirt, emergeing from behind the strap.

That's probably something on bystander's shirt. If what you're saying is true, then the magazine does not connect to the rifle. Pay attention to where the magazine seats on the M4. If you don't know where that is, find a diagram on google, you'll see what I mean.

Okay, I can't see where there's a magazine where it should be. Still, why would a smoke puff and spent casing be photoshopped in, but no mag? Are there shorter magazines?
