MFT Magazines. FYI

[JPB4BAMA]

Probably lots of discussion in the past about storing loaded magazines and it being bed for the spring, but never heard anything about the feed lips. So just today I was doing some straightening and had a couple of MFT mags that had been stored with a full compliment, when I dropped one by accident it basically stripped itself bare. Closer examination shows the feed lips have stretched out and no longer provide a tight fit. Looked at the second one and it was actually starting to "flip" the top round out without anything on my part. I have a magpull that has been camping out with these other two and it looks to be just fine.
Not intended to be a discussion on the merits or not of storing loaded, just and FYI for anyone that has these to take a look and make sure they seem OK.

Plastic, aluminum, or steel bodies?

These are plastic mags I picked up probably about 6 or 8 years ago. But only store loaded about a couple of years. Steel and the magpul plastic are fine. My guess is these were cheaper plastic, and to be honest the lips do look a little thinner than on the magpul.

Never store plastic lip mags loaded. Thats a bunch of pressure

Thus I have learned, and some seem to be worse than others.
