Handling maybe? Slower lugging that thing out, zooming ect? Could work... More stagger when getting shot while scoped has beem suggested in the past as well, which wouldnt be unreasonable I dont think either (cant say how many times ive been killed/ got kills while under heavy fire that quite frankly went deserved...) Another great possibility would be sway instead of holding it perfectly still, dead centre, head level on that door way...
