Not that I want to offend you, but this picture shows perfectly that people who are trying to play soldiers are just playing. Guess what happens when you fire a real rifle in this position.

You find out how flat that wall behind you is....or how much your butt really hurts when you hit the ground.

Na, I thought about finding out how painfull a scope can be that tries to enter your skull thanks to the rifle that slipped up your shoulder because of the blowback.

That looks like a 5.56NATO rifle and the 5.56 has a low recoil index for individual shots.
Still he would have issues with keeping the scope on target.

Not real obviously :/
