I have many 223 magazines, and more for my numerous pistols. My question is do you need to unload the mags to ease the springs. When I was in the military we never stripped our mags unless the armory wanted to do an ammo count. And when I was a civilian policeman, we only did it when we went to the range to take out our duty ammo and load range ammo. Is stripping the ammo necessary for magazine maintenance?
