Every AR-15 or rifle that takes an AR-15 magazine should ship with one of these. These Magpul mags are solid, lightweight, durable, lock into place easily, drop free, and don’t rattle like GI style aluminum magazines do.
Magpul mags are a great item to stock up on for a gun lover or even a prepper. After all, it’s hard to use your ammo stockpile if you have to load it all one magazine at a time. Plus, in the event of an assault weapons ban, you’ll want magazines that have a very long life so you can keep shooting your guns as intended (presumably, you’ll want to be able to pass these down or sell them off later, too.)
The included plastic cover is a neat feature for storage and pops on and off easily. The mags also come apart easily enough for replacing worn springs and followers (to greatly extend the life of the magazines).
These non-windowed magazines aren’t as fancy, but they are every bit as sturdy and you’ll save a few bucks a piece. So, it wouldn’t be a bad idea to stock up on these to save for a later time or to use in intense training and shooting events without feeling bad about damaging them.
