Shotgun? Proof marks are your best bet. I've found this list to be useful although I can't vouch for its complete accuracy. There's a small square on the bottom of the receiver just above the trigger guard that contains the letters. In the case of my M1's and M2's it appears accurate based on my knowledge of when I got the guns.

Matthew, all I can say is that chart above shows 1989 which was before the 1993 AWB so I'd call it pre-ban. I don't recall any other bans for shotguns. I think the best part is the factory early models can stay that way without having to worry about 922r compliance with changed parts to make the same thing.

I have a couple of M3T's. Those are the top fold tactical folders that are quite uncommon, maybe even rare. I've heard all kinds of numbers for them, with most saying 180 of them in the USA and allegedly used at nuclear power plant facilities. That is all hear-say though so take it for what it's worth. 20200423_120155.thumb.jpg.53c68a573c22c8749dde86296fb02dc2.jpgas for use at nuclear
