u/DUH455T

I've got an AR pistol I've got a pending Form 1 on. I'm interested mostly to avoid any legal issues that could arise due to various attachments (stock, grip, etc). More or less, the more I read about them, the more I'm considering withdrawing the application. Seems I'm trading rules about how I can configure the weapon with rules about how I must store and transport the weapon. Crossing state lines can be troublesome. Needs to be engraved. Supposed to be stored in specific ways. Anything else I should know before following through or withdrawing?
