What gorceries can you name that have been hit with the shrink ray?
Technically AR magazines are throw a waysWhile the military M16 magazines can be reloaded, in combat they're toss asideThey're not really designed to last forever.
Magpul's PMAG magazines are some of the best all-around STANAG-compatible magazines in existenceOn the other hand, I've heard that ProMags tend to be poor qualityYour mileage may vary, depending upon brand and model.
Depends on the brandPersonally I like the Magpul PMAG and EMAGI would say that they are both extremely reliable and better than the standard GI aluminium magazineJust looking at some videos of it, people run over magpul brands and they tend to work even after a lot of abuseI know the military issues pmags and I know at least the British infantry issues emags for their troops to use in their weaponEven with steel/aluminium mags, they tend to contain plastic followers on themSo no matter what you get some plastic in your gunAs far as other plastic brands, I'm not so sureI heard various things about themI only buy Magpul PMAG/EMAGs and the NHMTG aluminium magsI haven't had any issues with either of them and I find the Magpul brands to be somewhat better in the long runIn general, the classification is difficult in the magazine worldGenerally speaking NHMTG, Magpul, Colt, and DH are considered top quality magazinesOther than that there are mixed resultsThe problem with other polymer mags tend to be that they don't have good followers on them or they melt / deform under extreme temps such as putting them into a hot gunA magpul won't do thatEdit: MSAR is considered somewhat okay but most people would agree that for the price you can get one, just buying a quality Magpul one is far betterMost people buy MSAR just for trying out a new product or getting a range magOtherwise, when it's go time, Magpul brands would be what they wantAs I said above (and Mr 357 below said), other plastic brands tend to handle heat differently even though they are made of the same materialJust because Magpul is made of polymer it doesn't mean it's the same thing that is in an MSAR or other brand.
Although some of my friends swear by those magazines, I would much rather stay old school and stick with American made metal magazinesHaven't had a single problem with any of mine.
