How can i animate this arrow loading for bow more efficiently?

Hello, so i am making a bow, that's realistic, yet still fun to use. I'm currently stuck, because i can't figure out a better way to animate arrow loading than just preparing multiple parts to which i would teleport the arrow frame by frame, but that seems super inefficient and i was wondering how could i make it work smoother and that wouldn't use so much of parts. Note that you can't use something like a part.position = part.position - Vector3.new(0,0,1) because the bows location and rotation is constantly changing... and that's why i need help. Would appreciate if someone could suggest a better way.
