My .308 started acting up at the range again yesterday. Out of the box the mag was loose. I had to send it back to Cabelas for a replacement. I also purchased a second mag. After 100 rounds both are starting to slip at the rear.First noticed when my rounds weren't loading. I can bend the tab but it would only be a matter of time. I consider this an inherent flaw in the design. Hopefuly, my fix will be a small bit of stiff rubber fitted and Gooped on the side of the mag to hold the metal tab more open. Keeping the mag tightly snapped in all depends on that little hook resting on to of the ledge inside. That is until the front clip gets weak.
