Do you keep your AR-15 mags loaded?

I agree with South Park and keep a couple of P-mags loaded. I have had some cheap mags in the past that developed feeding problems after being left fully loaded for about 6 months, but have had no issues with good quality magazines.

I have a DSA 58 carbine .308 cal loaded with a full 20 round magazine in my safe. It was in there for a year and I took it to the range to cycle my ammo. I never had a problem expending the ammo and all 20 rounds fired. The springs do not weaken if you have a quality mag. The same with my semi-autos. I load my Springfield XD with the full 12 rounds and one in the chamber and never had a problem. Use the magazine to its full capacity.
