So went and shot my newly built AR and I was getting a lot of nose dives, the problem occured when using both usgi and pmags. When i got home i noticed that my feed ramps didn't line up all the way. I am new to ARs and decided to post the pics here to see what you guys think.
please forgive the pics, they are not the good and the rifle is really dirty:
