Do you keep the mags jammed for long periods of time, or do you shoot often enough to cycle through them? While deployed overseas we would keep bags of M4 mags loaded for our "speed balls". Over time the springs will become weak. And cause feeding problems. But those were gov issue mags not high quality HK or Magpull magazines
