6pt, That' s not all that common, but not at all unheard of. Happened to me just last year with one of those Simms Stabilizer Enhancers. Very first shot I took with the thing mounted on the bow, the piece of junk snapped off.

The dealer replaced it and I shot with it for a month or so, but I decided I was just as well off without it. It' s been gathering dust in the junk drawer ever since.
