Need a little advice on magazines for my AR15.How long can you leave the mags loaded up without weakining the spring in the mag? :usa:

Probably about 30 years. Loading and unloading them will cause more fatigue than leaving them loaded. If you are storing them for long term storage leave them unloaded. If you are keeping some in the closet in case you have to head for the hills keep them loaded and check them every couple of years. Springs are cheap. JMHO.
