You may have been able to order special serial numbers from them

This a a gas trap receiver imported by Federal Ordnance. They were just complying with the law in marking an imported receiver. This one has the square notch receiver cut, and the seventh round modification.

The 2,5xx,xxx number gun seems to be correct. That is, serial number matches the drawing number and revision. The other code is the heat lot. Your gas cylinder lock screw relief valve is usually sloppy with M5 bayonets. Not to worry. The modified 98 bayonet is kind of hard to find. I haven't seen too many.

T in the circle means trademark. They continued the numbering from where they left off after Korea. I don't understand the 3 digit number but there's more than meets the eye from what I can make out.
Jim,
When SA, INC. Geneseo, IL., started production on new cast receivers, they were duplicating military M! receiver serial numbers. BATF told them early-on to start a 7,000,000, well after military M1 serial numbering was over. It's unknown how many 3-digits were made, perhaps 500 or so.

That's the first I heard of it. Thanks for the info.
Jesse, I can't tell if your gas cylinder was modified or not but I thought they would have done the bayonets. Maybe not. You can get replacement parts easily through our WTB here. Make sure you state what you have and the guys will come forward with proper parts.

Ramboueille,
So Geneseo started duplicating original M1 reciever numbers by starting over with low numbers and then forced to go to 7M?
Also any idea on what the steel would have been on the earlys? Triple alloy like an 8720, 8740?

Jesse,
Yes.
Unknown what steel they used for the new receivers. I know that a year or two after the directive to use the 7 million block, SA, INC. tried to buy back the 3 digit receivers. A small group of us had already bought several of them and on a routine phone call to SA, INC about obtaining some parts for them, they asked what our serial numbers were and made an offer to buy them back. I don't remember what the offer was. None of us returned them.
