Scene from The Walking Dead. What's wrong with the above picture? Read on to find out.

So what's wrong with the above picture? First, notice the character's off hand. He's holding a pretty sharp knife in it, while attempting to support his rifle at the same time. Not a very good idea.

Next, notice how he's intently peering through the sights. Wait, did I say sights? I should have said "sight". If you look closely at the picture, notice that the rifle is missing the rear sight! This person must be one heck of an expert shot to not need a rear sight!
