Was thinking the same thing. So “80%” is no longer a demarcation line due to a fallible argument that all guns need to be on Guv’s radar. That means the prior tongue-in-cheek statement over recent years that we simply move PMF kits to 70% ready, or 60% and requiring an additional hour of shop time to complete, etc…no longer hold water.

That’s about readily as ‘readily converted’ as it gets. Place block of aluminum bar stock in CNC, close door, power on, and press start.

Boom, done.

Not good, people…

The latest example of this dynamic came on Wednesday, when Barrett signed on to the Supreme Court’s decision in Bondi v. Vanderstok. In its 7-2 ruling, the high court’s majority upheld restrictions put forward by the Biden ATF on so-called ‘ghost guns’ that, according to Fox News, Second Amendment advocacy groups have characterized as ‘unconstitutional and abusive’.
