Factory says 17-19, or 18 can't remember. But in reality maybe 14-15, consistently. In terms of rate of fire, you can adjust from semi-auto, 3 round burst, 6 round burst, and full auto.
well on that type of gun (not dissing anyones gear) the board cant handle high rates of fire consistantly you could shoot 17 on it for a second and keep shooting it 17 but the board will drop it down 2-3bps because jt focuses more on cosmetics than they do the quality of their boards
