I have a customer ordering extra arts incase the Zombies attack and was asked if buffers ever break? In 18years in the military and in personal use I have never seen a broken one, you guys?
I have seen them crack where the bumper is cross-pinned
Most common: Walking pins. Easily corrected.
I have seen some soft pins, flaking/peeling, and other indications that it was a junk part overall. Given the origin, it wasn’t surprising.
