What chaps my ass is gun folks thinking that going right up to, but not past, a legal line that seemed clearly defined, is somehow wrong or foolhardy. This is nothing new. That is why there is a line. If you stay on the legal side of that line that should be enough.
One of my fav hunting honey holes is a 1 mile square of public land surrounded by private land. Last year I dropped an antelope at 638 yards , 80 feet from the unmarked property line. BUT I had been out there with the gps and knew exactly where the line was so I took a VERY legal shot and dropped it where it stood. I was close to a defined line but still on the legal side of it. No foul.....
Furthermore, if you think this is about braces you are delusional. When the ATF pulled this crap with bump-stocks, intelligent 2Aers knew where that precedent was headed. The atf is flexing their muscles to create ambiguity and increase their power. They want to legislate through bureaucracy and on the fly.
2Aers need to fight these new power-grabs with everything we have or this just will not end well for us. We need to find legislators that will help rein in the atf via budget, legislation etc.
