With pmag prices hitting all time lows, is there a single reason not to stockpile the crap out them? Gen 3 have been on sale for $8. So why not?

Now that prices are down to around normal are you going to start stockpiling magazines? The way I see it, it is just a matter of time before there is another Sandy Hook and the government starts talking about gun control. Which will spur panic buying. For the first 6 - 7 months of 2013...

I have 20 round mags for my Mini 14 and M1A, but the standard magazine for the AR platform seems to be 30 rounds. Now is definitely not the time to be buying AR magazines, but that is what was thrust upon me. In the unlikely even that I get to choose, I have decided that the Magpul Pmag is right...

I bought myself a half dozen D&H magazines from my local dealer he has me believing that they are the same mags as Colt and bushmaster, is this true? also does anyone have any experience with these D&H mags? and is 18 bucks a piece OTD a good price for them? thanks HDW
