Some mounting plates are equipped with spring loaded anti-twist pins.

They are a pretty new development; they've only been around for 40 or 50 years now.

I think it is more than that long, but point taken. Normally I remove those pins if possible since they are not needed with dedicated A-S style plates.

I merely indicated that they exist. I didn't state that they were a new development. That's a matter of you reading something that that doesn't exist, for no other reason than to be critical.

My comment was a general one, intended mainly for the person who had never heard of them.
