The swordfish MP5 locked up on me last time I went to play. When the battery is plugged in, it just makes a clicking noise, and will not shoot. I tested the motor, and it works fine and the fuse also looks good, so I think there’s some jam in the gearbox. I only play around twice a year, so it’s not worth it for me to fix, but you might have better luck than me, which is why I’m selling it fairly cheap. The two batteries and charger, three high-capacity magazines, four mid-capacity magazines, and both mag pouches are all included.
