I just got my Colt upper and took it out for a test spin yesterday, and had problems getting the first round to chamber. I'm not sure what is causing this. I don't know it is because the gun is new, or my technique, or possibly the magazine. When I charge it, and pull the trigger, it doesn't fire. I then pull the charging handle again and it ejects the first round but still won't fire. I had this happen several times. Any suggestions as to what might cause this? I'm new to the AR platform, so go easy on me.
