I recently purchased an Automag III .30 carbine. It is in excellent condition and appears to have been used very little, if at all. I owned a Ruger .30 carbine 20 years ago and it was a great pistol so when I saw this gun I had to buy it. I took the Automag out and shot a couple mags through it. The last two rounds of each magazine didn't fully eject. Any thoughts? I don't see any reason for this to happen. Everything appears to be in great condition.
