Has anyone ever experienced the friction lock on a CTR to stop working the way it should be? What I mean is the movement with the lock disengaged is the same as when it is. I've taken the stock apart and examined the locking panels and they appear to be doing what they are supposed to be doing, but once assembled I cannot tell it is engaged.

Granted this little movement isn't a whole lot and I can live with it, but it is frustrating since I might as well have gotten the MOE stock or something similar. My CTR is a commercial sized if that matters any.

Thanks.
