Are you really this naive? Pro-gunners will have been fooled, if they think they can deal in good faith with anti-gunners by giving them the opportunity to redefine "full-auto" to encompass bump stocks or similar mechanisms and make them destructive devices that fall within the scope of NFA 1933 (as amended by a "Quasi-full-auto Act" QFA 2017).
I can bump-fire my ARs and AKs without a stock addition. But the ATF won't care about such "subtle" distinctions. They can now classify any SA rifle as potentially quasi-full-auto weapon, because they can be held in such a way that they will fire repeatedly using the same operating concept as a bump-stock.
I wasn't born yesterday.
you’re moving the goal posts now. I never said anything about redefining anything.
