I can tell you that the plastic Takka mags are very durable. Ive beat on mine as hard as i can to try to get it to fail. They do feel cheap but it is a great rifle. Its been through more then any other rifle ive owned. I took it bear hunting for 3 days. That is one of the roughest things you can do with a gun besides throw it off a mountain. It came out of the hunt like it was nothing. I would randomly try to fire a round to check the scope and to make sure the gun was working fine. It never misfired.
