I believe this answer hits the nail on the head. Not that I rank up there with IG, but I did experience this in one of my builds and I went crazy and drove my friends crazy on how to get it to eject "better". My AR's run a variety of buffet weights - all Vltor A5's. I have one AR, for whatever reason needs an A5H3 buffer and heavier spring (a Sprinco from Tactical Springs in Austin to cycle properly. Put a standard A5 Spring in the buffer tube - no joy, fails to cycle properly. Tried it all. My point is that I did all that buffer/spring swapping to find the right combo so my weapon would cycle properly. (After I ensured there wasn't a problem with how I built it.) Once I did that (thanks to DocSherm) my weapon cycled perfectly as advertised. Whether it ejects casings at 1300, 1400 is not a factor or reason to start tweaking or trying to fix something that isn't broken. IMO.
