Re: AR15 madizines
PMAG 10 pack $99.99 + $18.50 shipping, which is absurd, but right now all you can do is compare final prices after shipping.

Re: AR15 madizines
I've used hexmags with no complaints when magpul was scarce.

Re: AR15 madizines
Speaking from both experience as both a USMC infantryman and a civilian AR15 owner, the important difference between PMags and aluminum mags (assuming a quality manufacturer) is the ability to leave them loaded.
I had a lot of problems with my M16A2 and a lot had to do with double feeds. The double feeds were caused by aluminum mags with deformed feed lips. The deformed feed lips were caused by mags being loaded at or near capacity and the spring putting pressure on the rounds, pushing the feed lips out. Then multiple rounds push out the top. Sometimes even when the mag was inserted or handled roughly.
One of PMags' most important contributions was the storage caps. The storage cap actually applies pressure to the top round to push it down so it doesnt apply pressure to lips.
So can aluminum mags be reliable? Yes
Is it a good idea to buy Aluminum mags with an unknown history or use them to keep stored and stacked with ammo? Probably not
Buy quality aluminum mags if you want, use them and maintain them, but IMO stack ammo in "Ready to Go" PMags and use the top cover. This will give you the best odds of success.
YMMV

Re: AR15 madizines
I swear I read something that said that stuff about dust covers "relieving pressure" on pmags for long term storage us an internet myth.
I have to see if I can find it, but I thought it came from Magpul themselves.
I have been wrong before though.

Re: AR15 madizines
Honestly, this is one of those questions that simply cannot be answered definitively and ends up being personal preference. One's usage may indicate one or the other, but I still maintain that for most of us civilians, either polymer or good quality aluminum will be just fine. We have to realize both are disposables, and you have to monitor them and relegate questionable ones to range use only.
Chauncey is right, that using polymer mags with pressure relieving covers is probably ideal, not least of which because the cover may help protect feed lips in a drop on them. Aluminum mags are prone to feedlip spreading when dropped, polymers are prone to cracks when dropped on the feedlips. Other than Chauncey's post I have not read any complaints about feedlips actually spreading simply from being loaded, and not also being dropped. I'm not saying it cannot happen, I just think there is a lot of Internet echo about this and it may be more urban legend than actual fact.
I've always loaded my mags with 28, not recommending it, just what I do. But I'd leave aluminum mags loaded with 28 rounds for years and grab them when BLM-tifas roll by and be perfectly happy using them, YMMV, of course. I do think polymer mags with covers on is probably the best way to go, lose the covers if BLM-tifas start shit in your vicinity, they won't go bad in a matter of weeks, that's for sure, and you can replace the covers later when things cool down.
I'm keeping all my good mags, both metal and polymer and not replacing any of them unless they show signs of damage. I'm really indifferent to which I use.
I mentioned the instructor who recommends loading only 29, I found him, video below. Starts with typical YouTube time wasting, start at 2:30 for just the facts, ma'am.
