Magpul is about to move their manufacturing company from Colorado because of the crazy anti-gun atmosphere. Before they leave they are going to flood Colorado with high capacity magazines which will be banned by the legislation to be passed this coming Monday.
Check out their facebook page and see what a wonderful opportunity this is for the CO resident.
I have just purchased 15 magazines for my AR15 from Magpul with the average purchase price of $15 each. This purchase is part of the Boulder Airlift campaign being conducted by Magpul. It is only available to Colorado residents. You must go to the Magpul website or its facebook page and follow the links to register. After they verify your CO billing address and shipping address you will be notified to log in to a special magazine purchase page. They have limited the purchases to 5 magazines of each magazine item.
Currently the magazines are selling for $60 to $100 on gunbroker.com and eBay.
