Yeah, definitely has its downsides. One of the tips says to follow the contrails of an SMR to find out where the pilot shot from, but honestly that's the least of my worries when I use it. The smoke more than often blinds my view so I can't really say it's a good weapon. Still, the numbers don't lie, I'm clearly effective with it. I could probably be even more effective with a different weapon, but I'm attached to the SMR now.
