This bug has plagued the ARMA3 ever since first alpha. The feeling of when your gun suddenly doesn't recoil on some or most shots when turning your view, really disconnects the gameplay and ruins a bit of the immersion. The gun literally doesn't recoil at all, not just the model, but even the scope stays perfectly put when you carefully swing your view from left to right while firing.
Let's please get this finally fixed for a lot smoother and polished gun gameplay! :)
The attached video describes the effect completely and shows the effect and how to reproduce it.
