Yes that only 'disadvantage' of popping up, shooting and then falling prone is that you can't aim. There are a few feats that add bonuses if you aim. Also I don't see it much different between that and hiding behind full cover and popping out to fire and then moving back to full cover. This could also lead to people 'Readying' and shooting you as you stand...
I will all be great until a bunch of melee folks run up and stab you on the ground with advantage though
