This isn't too huge a deal, right? The damn thing likes to fall out all the time. I was cleaning my rifle and it popped out, I wasn't really paying attention and it got caught under another structure next to my work bench when I went to lay the rifle back on the bench so I could grab the tube. I didn't kink, just a slight bend that I've mostly fixed by bending it back. IMO this isn't a big deal but I'm far from an expert when it comes to guns. The upside to this is the slight bend that remains holds the thing in the magazine and locked into place. The rifle in question is a Winchester 9422.
