Fix it.

Although mags are disposable it's still very interesting to see how they hold up to adverse conditions.

Cool thread, makes me want to check out the tech side again.

I live in a very cold climate, I would like to buy a set of 8 mags for extreme cold weather use. Can someone in the know recommend a extreme cold weTher mag?

I use only P-Mags and GI and have not had a problem due to cold weather ever.
I have dropped plenty of mags on hard surface in all types of weather and the only mag I remember failing is a P-MAG that cracked when I stepped on it after dropping it on a 80* day in a class a number of years ago. Mags can fail, they are not meant to last forever.

If you test multiple magazines against each other, there is bound to be some small variation in impact force and angle, no matter how carefully you set up the test.

In other words:

No, the test isn't perfect.
Yes, it's still interesting.
Yes, the Magpul guys still sound whiny by complaining about it.

The problem with attempting to compare products is that the impact wasn't EXACTLY the same for each of them so product A may perform better than product B in one test but if several iterations are done, it can have the effect of smoothing out test anomalies. In other words, if the test were conducted multiple times with as strict a procedure as possible, the Troy or Lancer magazines might have developed a crack similar to the Magpul and Tapco magazines. Or they might not, but the only way to fairly compare them to each other is to perform multiple tests.


You should do that. A good way would be a secure way to hold the magazine and have a pendulum type device that could vary the amount of force depending how high it was dropped from. I think Fortier had a chute set up that dropped the magazines the same way but people that didn't like the results complained. There was a guy on this forum several years ago that crushed many magazines in a hydraulic press and recorded the results but the people that didn't like the results complained.

This is not a statistically significant sample size.

However, when a person buys a magazine, they are only getting a sample size of whatever they buy. So in that facet, this test is more like what a user might experience themselves.

Id like to see magazines left out in the sun for weeks or months and then tested to see if they became brittle, also chemical testing, just for fun. Maybe I will do that myself sometime. I think there's at least a 50% chance I can mix something up that would melt or soften some magazines.

The amount of UV they were exposed to would be equal to many years left outside.

Interesting, I mean that would make sense of course, I guess I guess I never considered that there was such a thing.

I know personally that's a big concern with polymer mags, or polymer guns in general, that they may handle a few hours in the sun for years, but given enough exposure they will fail early.

I'm guessing this plays into why Magpul only offers Black and Sand now.

Sun exposure test.

Since that one's in GD, and not in a tech forum, it may or may not be followed through on, but is an interesting idea.

Those of us that live in states that no longer allow buying new 30rd mags have a slightly different view on things...

This thread got me wondering about the USSR transition with the AKM to 74 and accompying mags.
