you can usually tell buy looking at the gearbox but its not a great idea to pull apart your first gun. you can tell if they are bushings just by looking at them. plastic does not last as long but they will be fine for you to play with.
Please be safe and have fun. hopefully by the time your 18 and play with us you will be a good asset with the practice you had. Good luck
