So I'm at the point where I no longer believe that leaving my mags loaded will kill the springs, but I'm now wondering if doing so will damage the feedlips? Or the tube body in any way? I have always been against leaving my mags loaded for long periods so I was just wondering if there was any additional stress I should know about. Also, on this subject, I just got some new Lancer AWMs and the baseplate is polymer like the rest of the mag, I thought they were rubber? Did they change that recently? Thanks for any help!

Ok thanks for the info! I got these specifically because I'd heard PMAGs had issues with feedlips cracking.

The Army's Asymmetrical Warfare Group, CAG, and SF groups have done some long term studies on this in the past few years. They disproved two things.

1. Leaving mags loaded will NOT fatigue the springs or mess up the feed lips.

2. Using the magazine as a mono-pod will not cause feeding issues. I have qualified with my rifle sitting on the magazine for a few years now. I use it that in both the prone "supported" and "unsupported" iterations so that my grip and stabilization is consistent throughout. Works great.

Millions of Pmags vs a handful of internet pictures.

I have a couple loaded uncapped and untouched since 12/2008 with no problems.

This.

Also, I've had USGI mags loaded for upwards of five years before taking them out to shoot and have had no feedlip issues or malfunctions.

I'd load them all if I could. But my stash is currently an unorganized pile of mess. I lose track of what type of ammo is in what mag. So I keep mags loaded for what I need and keep the rest in their boxes.

+1 for the previous post's.

The Lancer L5 and L5A magazines had rubber baseplates the L5AWM's have always been polymer.

I had some usgi mags loaded for 6-7 years. I had forgotten about them. Anywho... they ran fine. Not one hiccup or deformed magazine

Quality gi-style magazines can take decades of setting loaded with no problem. I've had some old GI aluminums sitting loaded (to 28) for literally more than 20 years and they're fine. Still use them on occasion just to have a relatively current 'test' of them, but they get immediately reloaded.

I like L5AWM's and figure that with their feedlips being hardened steel, they're likely to be even more resistant to warping than the aluminum mags are. Can't know for certain, obviously, since they don't have that many years behind them; but in the year or so I've been using them, they've been great and very stable.
