Thanks for the help guys. I did try 2 different types of magazines with the same result. The Scenar loads will not single feed either. Of course they can be single loaded into the chamber, fired, and eject just fine. The barrel and upper have m-4 feed ramps that appear to line up as well anything else I have assembled. I have a friend with a magazine made by AA, I'll try it next and also try the ammo in his gun. The fired cases on the Hornady ammo show two tiny bites on the the neck and the bottom part of the case so they must be hitting also. It may be the magazine not holding the round up high enough or the feed angle is wrong. I'll take some pictures.
The upper and lower are Aero Precision, the bolt is from LBC. What should the height of the mag be in relation to the receiver, maybe there is a problem. The receiver has not been used before. The upper worked fine with a different barrel. I can also try the upper on a Daniel Defense factory built rifle.
Is it possible the feed ramps are too narrow at the top? I was under the impression the bullet normally will not touch the ramps if everything is working correctly.
I'll give some of this stuff a try and give post an update.
