The infringement is on our Right to build a gun from scratch. Naturally, the AFT had to define the line between "scratch" and an actual gun. They originally defined it as 80%. So, there we had it. It was a concrete line with a solid basis for abiding the law.
Now they're moving the goalposts ARBITRARILY and VAGUELY, effectively eliminating that Right.
They are further infringing our Rights by effectively instituting gun REGISTRATION. Right before our eyes, and some refuse to see it, because some think building pistols is icky and doesn't interest or affect them. They diminish and disparage the hobby with trite comparisons to "sanding and polishing." "They just want a serial number on it. That's not infringing your rights."
What if I want to "sand and polish" a rectangular block of aluminum or plastic? What if I want to melt and spray a spool of nylon into a 100% frame?
So, now the tyrants and alphabet agencies want 80% frames designated as "guns" and therefore entered into their system via serialization and 4473 checks. What about 70%? What about 50%? What about ZERO %??
None of that is hyperbole or rhetoric. It's an honest question. Where is the line NOW? Tomorrow?
The early results of the poll on my forum indicate that a majority of hobbyists will be moving to ZERO PERCENT "frames" by printing their own. Building our own guns has been legal since the birth of our nation, regardless of technology. Of course, there is also milling with old-fashioned lathes or even computerized lathes. And now we have 3D printing available to the masses. All of that technology is getting cheaper. Once you have the machine, a frame can be printed for less than $10.
So, THEN what are your tyrants going to do? Ban or register spools of nylon? Blocks of aluminum? Actually, no. Of course not.
But, here's what they WILL do: They will insist that ALL guns be REGISTERED. Any gun that is not serialized and registered in the system will be illegal. We all SHOULD know that. And we all SHOULD know what comes after registration. Every time. 100% of every instance of gun registration has ended in confiscation.
This is not a "Slippery Slope" logical fallacy. They've TOLD us they're going to do it. In no uncertain terms, they have literally said, "We are coming to take your guns."
You may not be interested in building your own guns. But, you should be VERY concerned. Because they ARE coming for YOUR guns. That's also not hyperbole or speculation. They have outright SAID it. When they TELL you they're coming for your guns, you should believe them. When they make incremental efforts towards that goal, you should believe them.
