I was asked this question by another shooter who was using this weapon the other day at a local range. He asked my group "what would be causing the AR-15 to Stove Pipe a round while shooting?" He also stated that he was shooting Hornady and stated that the firearm was clean. He also said that the firearm was produced by Hi-Point, I believe, which I had no idea that they had an "AR" line. Since I know jack about "AR's" that's no surprise. No one in our group had a legitimate answer for him. So, what could be the cause, bad ejector? I know very little about this platform and if the question ever came up again, I would at least have some good information to pass on. Thanks!
