Back on the I24 beta, the assault rifle instant-snipe had a few issues with it. Thankfully, the redraw problem is essentially a non-issue now, but it doesn't fire instantly like it did back then.
AR's snipe in i24 was the fastest in the game at about 0.60ish seconds to fire off, now it takes roughly 3s as your character lines up a shot.
If that's intended behavior for now, fine - but it's not how it worked back then, so I figured something was up. The instant-firing is what was going to make AR paired with either energy or devices a pretty insane combo.
