I know this has been brought up several times to the point of jambog, but I have a question. How long can you keep a USGI mag loaded without failures? I know its the compression/decompression that makes the springs weak, but how long have you guys kept your mags loaded for and have them still be reliable? I tried to search function but my search-fu is not so sharp at 0229. Thanks capt Wanna kill these ads? We can help!
