More like a failure to go into battery, causing a failure to fire or
failure to extract, causing a double feed jam.

He's talking about the AR-15 he "built", and there's really nothing to headspace on one. If the barrel and receiver are properly machined to spec, it has the proper headspace built into the design. When it becomes important is when you are fitting a more traditional barrel and receiver together, and are doing the machining yourself. Let's say you have a Mauser 98 action, and you're building a 30-06 with a Shaw barrel. Then you have to check and machine in the correct headspace, and even then it's not hard to do.


Another fabricated Fat Harry story?


Barrels in sporting rifles don't headspace themselves automatically, and
it is worth taking a few minutes to check it. If JackOff wants to take
the chance of a kaboom, it is fine with me.
