Nick, I have a question as well. Last year at the Harrisburg sportsmans show I purchased a dozen turbo nocks. I told the lady at the counter that they need to fit on a dozen easton axis arrows that I would be recieving. She handed me a pack and told me that they would deffinately fit. Needless to say when I got the arrows they weren't even close to fitting. Now I have a dozen nocks that won't fit on anything I own. How do I go about getting the right size since I bought them at the show?
