I've owned my super 90 m1 for over 25 years, and put more than 11000 rounds through it, and never come across any of these problems. Actually, when I pull it apart and clean it, it looks more or less as it did +25 years ago... Scuffs and marks and some shiny spots on the blackened parts of cause, but overall as new. The very few times it has missed, it always has been ammo failure.(wet, stored improper, aso) Have I've just been lucky or what?
