The owner of an Army surplus store, United States Army Reserve Warrant Officer and commanders adviser on maintenance issues, wrote about his experiments testing how well Magpul PMAGs hold up against some of the chemicals that soldiers sometimes carry.

I look forward to further testing. It makes sense to test how well the polymer magazines you carry hold up against the chemicals you carry, just as it makes sense to see how much abuse your aluminum magazines can withstand.
