I'm not here to debate about the pistol brace topic. I just want to remind everyone that the Pistol brace 120 day amnesty period has gone into effect today. So be wary if you want to use your pistol braced firearm at a public range or if its your truck gun. However, the ruling has not been accepted into the federal register yet.
If you know people who have pistol braced firearms but don't keep up with firearm/NFA laws, be sure to give them a heads up about this unconstitutional ruling.
Edit: updated some info in my post above.
