That is most likely a magazine or less likely a buffer/ buffer spring issue, not remotely an ammunition issue. If at anytime an AR starts acting up, the magazine is the first suspect.
As for the OP. I wouldn't buy a DPMS unless I had no or very few other options. I certainly wouldn't pay more than $6-650 for one. As mentioned above... To sell rifles for what they do, corners are cut.
