Protostar arrows.

I know this is a dumb question but it’s bugging me. How do I use the arrows on my protostar whenever I tighten it the arrows aren’t allined. How do I do it right…?

Its a normal issue for protostars sometimes the protostars arrows are aligned and work but most of the time they wont align so dont try to overtighten it to the arrows. Even my arrows on my protostar dont work lol i just tighten until i feel its about right

Mine and my kid’s Protostars and my Northstar, I just line the arrows back up and they play about as good as they are gonna play. Works fine every time.

same with the grind machine it dosent really matter
