Whenever I ADS with Scarab+Reflex sight and fire, the weapon movement is really sluggish. It's been like this since the very beta, and I couldn't quite put my finger on it till today.

It appears there is indeed some kind of lag, at least for me with this weapon. Whenever I (aim down)shoot it feels like one of these things:input lag,micro-stutter,slow ADS mouse sensitivity. But I'm talking about milliseconds of this occurrence. I get this problem only with this gun, other weapons fully auto or not, they fire and move just fine in ADS.
