Ok, I've watch this thread grow, but I don't know what an anti-tilt buffer is, someone mind explaining?

All AR's can have bolt bounce where the bolt carrier doesn't go straight back into the buffer tube. Piston guns are more prone to this because the force pushing the BCG back comes from the top instead on the middle of the bolt carrier group. An anti-tilt buffer reduces any bolt bounce that can cause wear on your buffer tube.
