LOOKS LIKE HOOKSTER WAS HITTING THE SEND BUTTON WHILE I WAS STILL TYPING

 

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

I have a mossy oak long barrel 12 that I found the serial number, starting with a V and ending in a C. Need some info to sell. Year, model, etc... any help would be great.

Bambihunter.. those are some really nice units there. Is there any chance you could take some photos of the locking mechanism if possible? Probably a long shot but I wanted to try and ask at least. 
thank you. 👍🏻

Sorry for the delay, I've been so busy with life. I haven't been logging in very often anymore.

I sent you a PM, I think you can respond to it with low post count if another member initiates it.

I can next time I get in that safe. I still have them both. The folders lock into the rear sight. I forget exactly, but I think it is in a slightly different location on the barrel (~3/16" if memory serves), and the stock (of course) as is the sight it has the push button detent to lock/unlock. I do know one can't simply take a folding stock and add it to regular HK era M3 and make it work. I don't think there is any chance of making it work on the modern M3 without a fair amount of fitting. I have never seen a M3T folder made after HK era which I believe ended somewhere between '98 - 2001 I think.

Thank you for your reply. I have the HK M3 Super 90 with the folding stock. Looks like someone changed the barrel out at some point.
 

I was just curious if that locking mechanism is part of the barrel or is it fastened with hardware somehow to the barrel. 👍
