I saw the drill the others had to go through with Iron Ridge - from what I read, IR claimed the receivers were fine, this kind of thing was "normal", and the band aid on the buffer was the "fix".
Maybe I am expecting too much, but my thinking is that when someone offers a DPMS receiver, it should actually be made to those specs. Not a "you can use DPMS parts, but midificaitons will be required to get it right".
"DPMS" or "Armalite" style should not make any difference. If the buffer is contacting the buffer retainer when the bolt is locked, then there is a problem with the buffer retainer hole position, or the chamber is allowing the bcg to move to far forward.
I run the back of the bolt carriers over a flat stone to ensure they are free of any burrs. I have never had any wear issues with the buffer face, The anodizing well start to show wear after some time.
I'm surprised IR claimed the receivers were fine, this kind of thing was normal. It is not normal
