There are no 20 or 30 round AR mags to be found for sale on the interwebz. Everywhere you look… Gone. Opportunists seeking to capitalize on “Mayan-Zombie” and/or “Government Thug Confiscator” fearing gun owners have snapped up everything they can.
If you don’t mind being gouged on ebay or gunbroker, you too can by a $15 mag for $60; $50 each if you buy in bulk of 300.
I think I’ll just wait for them to get back in stock at the regular sources and pay something less than the price of a full tank of gas for my truck…
