Hey, I just bought a fresh new pack of Strikers and put them on my arrows when I noticed something that looked a little weird. There is about a fingernail-sized gap between the ferrule and the washers that hold the blades in place. It looks like either the ferrules are a fraction of an inch too short or the blades are a fraction of an inch too long. I screwed the heads in as tightly as I can and fiddled with setting the blades in about for about an hour with the same results. Is this normal? It seems like there shouldn't be any gap between the head and the washers???
