Re: US made compliance parts
Did you get it in writing? Asking someone on a point of law, and then, because they said it was okay, doing it, is foolish. Six months down the line, when you get arrested, and you say, "Agent Smith said it was legal", it's your word against his. You got something saying it's legal, on ATF letterhead, signed by a real person, you're covered.
