Another solid product - Safariland 7742 AR-15 Magazine Doubler 7742-215-2

This grips both magazines securely. I tried it with my MagPul Magazines, but it didn't fit so I had to use standard metal ones. It staggers the magazines and makes reloading fast and easy. The "top round protector" is a little odd, but after a few minutes of practicing with it, it easily pops off and clears out of the way. Safariland always makes a quality product and this is no exception.
