As the saying goes, "this too will pass (go away)". I was talking to my buddy I sold an AR to last year, and he wants to purchase 10 mags. My question is why, I gave him 3 mags with the rifle. First you can refill the mags when they run out, second 10 mags will not help you unless you are in a war zone and I would rather have more fingers on the triggers than try to do it all by myself.
Personally, I think this panic buying is silly just wait, there are millions of mags out there and even if there is a ban on new mags the pre-ban mags will hit the market sooner or later.
Just sit tight and don't shoot till you see the whites of their eyes.
