Don't grip the mag well and keep your nose on the charging handle. Another thing when shooting, keep your elbows in, not cocked out like you're elbowing someone. Keep it tight, you'll notice your groupings will shrink. If you want a quick zero, buy the Military M4/M16 zero targets. 30 meters represents a 300 meter target, or when 62 grain M855 hits at point of sight.
