Seen that on none collapsible stocks also. Question, was the latch engaged when this happened? That is the one thing that worries me about the ATI, if you don't engage the latch, it will slip. I will shoot these a little more and decide, but I would be interested in this, since I looked at the stock early when I got it, and it feels very solid. I will walk through them to be sure though, I don't tend to ignore warnings without looking.
One problem with youth stocks vs something like the ATI, having the correct length of pull for a youth is critical to reduce felt recoil. With that in mind, a youth stock does not fit kids from 12 to 17, ranging in size from under 5 ft to over 6'4". Anyway, thanks for the pic Tim, I will go and do some research and look at the stock. Deer is over here for the year, so this isn't going to get much more this year.
