Back to my original question:

Answer: Reloads, Not factory loads. (fired brass is no longer factory ammo)

So let's try again:

Did you try any factory loads in it? If so, did they work?

This is one of the reasons why gun manufacturers usually have a disclaimer that reloads void the warranty.

IF FACTORY AMMO WORKS, which you haven't answered yet, then:

If you tried an unsized case, then that just means your last AR had a large chamber.

If you tried a sized, but untrimmed case, that means your case length was too long.

If you tried a sized and trimmed case, it means that your chamber is tight (a match chamber, for example) and the die is not sizing the case down enough and you need small base dies. OR you didn't set up the sizing die correctly and the case length is too long.

IF FACTORY AMMO WORKS, All of the above are the fault of the reloader, NOT the manufacturer.
