There are plenty of people out there that stock piled various firearm magazines in the last 2 years, especially after the Connecticut shooting when everyone thought that President Obama would have the Political climate to ban the AR15. I won’t ask all of you reading this, to raise your hands if you actually thought that would happen. I found it embarrassing to watch people panic. I had a friend who recently picked up his first AR15 a Colt 6920 and got a pretty good deal but it looked like it was sitting around for awhile from a Y2K panic buy, apparently the seller had large quantities of magazines for sale and he asked if it was a good deal.
I told him to buy whatever he wanted but if he was buying large quantities of them he better test them out before he thinks they are all going to work in his AR. Gun magazines are like wine, they need to be store properly, and all are made on different dates. There is truth to the fact that a Magpul Pmag will not be durable 30yrs from now just based on it’s material break down, and metal magazines won’t if stored properly, but how bad is your outlook on life if you have to worry about that? If you got a good buy on bulk magazines take atleast a half dozen of them and test them on the range and make sure they drop free, rotate the magazines when you use them, and when they need to be tossed out, open up the packaged ones and test them out again. Don’t expect the brand spankin newly wrapped magazines to work, I’ve one too many times seen people have issues with magazine dropp
