Anyone have one of these? My dad has one and the original mag. I recently did a complete redo on the stock and it turned out looking almost new. The only problem it has is that the mag does not stay in place. It holds in the well, but comes down just far enough so that the bolt can't catch the round, the only way to fire it consistently is to actually hold the mag in place which throws off my hold and there for my aim. Anyone had this problem? Is it the mag wearing out or the well? I don't want to spend $30-$50 on a new mag just to have it do the same.
