Rob of AK Operators Union performs a small torture test of the Magpul AK47 Gen 3 Magazine with his AK. He drops the gun onto concrete so that it falls and hits the magazine.
Then he drops them in dirt and covers them up before using them in his DDI AK.
The final test is a creek bath with a nice dose of mud.
He performs these tests with a normal Magpul magazine and another with a ranger plate. He experienced a malfunction but that was due to the recoil spring. The test is short and sweet. I would have liked to seen a larger pool of data rather than just three tests on 2 magazines.
