Consumers can purchase 5.56 caliber magazines for automatic rifles online through gun and ammunition specialty retailers such as GunMagWarehouse.com, CheaperThanDirt.com and JoeBobOutfitters.com. Auction sites such as eBay.com also commonly contain listings for both new and used 5.56 caliber magazines.
GunMagWarehouse.com allows users to view all 5.56 caliber magazines based on the type of automatic rifle for which they are compatible. Viewing an entire collection displays the listing for each magazine in a grid format, which consists of a picture of the magazine above its name, model and price, as of 2015.
Hovering over a listing with the mouse cursor displays any special notifications about the specific magazine, such as if it is currently on sale. Clicking on an individual magazine launches a more detailed page that contains a more detailed description of the magazines features as well as links to share the listing on various social media platforms. Each listing also contains links to related products, as determined by past user behavior.
