^ so your rear trunnion is safe an your shoulder is OK, but what about the rest of your gun(ie. Op rod, GB).^
It's also a force that's being applied above the bolt carrier's rails. So if it's enough of a shock since it's a very short stroke, I think it could even bend your rails over time, since it is trying to rotate the bolt carrier a certain amount.
A buffer isn't really going to help if it's getting slammed excessively hard, it's more like something to prevent metal on metal contact should the bolt travel that far. I would never think of it as something that makes it ok to over-gas the gun. In fact, I'm willing to bet that mindset is why so many people have issues with them, and why I never have. My buffer was just getting some oil marks off the back of the bolt carrier when I was running 3" mags with the booster piston and auto plug, even with the auto plug set to run winchester AA.
