2 serial numbers on one firearm???

[Nothingontv]

Looking for some feedback here incase anyone has experience. This is only an issue because the new process requires me to upload a photo of the completed rifle.

I did search for this issue and could not find anything recent on it so here it goes. If you need to move this thread to another, my bad for starting it in the wrong spot.

HERE IS THE DEAL:

Missed the vol reg deadline on 3 of my self-built ARs from 80%ers. They did already have self assigned serial numbers on them which I noted in the application requesting DOJ serial numbers.

Shockingly, I got quick response with the new serials to mark on the rifle.

Here is the potential issue:

• Will the DOJ care if I have two serials on the lower? If they don't, go ahead and ignore the rest of these questions.
• would it help if I have my engraver strike through the old serial #?
• or I leave two on the rifle, I guess I could label the new serial #, "DOJ Assigned Serial # XXXXXXXXX" on the rifle.
• And I guess while I am asking questions, I had one lower that was previously marked multi for the caliber but registered it with 556 to avoid them rejecting a multi caliber rifle. I probably need to strike through this as well and list .556

Any thoughts?

Thanks

Using the AW registration as a guide sensee they required a second serial number, they had me list the original serial number under "other markings". Also, if the receiver is marked "multi" they except that for caliber. Where I had an issue is with a factory receiver with no caliber on it paired with a different brand upper with no caliber marked on it or the barrel. It took several extra pics and go back and forth before they excepted it as a multi.

DOJ does not care if you have 2 serials. Use the one they assigned to you. Put the old serial number in the "other number" box.

Do NOT obliterate the old serial number, that is a federal felony.

Regarding the caliber, I don't believe the vol-reg form even asks you for the caliber, does it? Either way, DOJ usually wants you to select whatever is written on the receiver, in your case "multi".

Your new DOJ serial number will start with "FMBUS" followed by a number, so is easily distinguishable by LEO from your self-applied serial number.

Thank you. I already completed the application. The vol reg does ask for the caliber, that is where i put in 556. I'm just wandering if that is where I'll have problem. If they take "multi" instead of 556 then I'm good.

I am hoping I just need to add the DOJ assigned Serial to my lower - since i already have all of the other info already engraved on it.

The other thing is they are asking for me to mark the manufacturer as "US"

It does, thank you!

This is what they are requiring in case anyone is wondering:

If you applied for a unique serial number to manufacture or assemble a firearm, within 10 calendar days of manufacturing or assembling the firearm, you shall engrave, cast, stamp (impress), or place the unique serial number and additional information in a conspicuous location on the receiver or frame of your self-manufactured or self-assembled firearm. By the end of the 30th day from the date of this letter, you must upload four digital images of the
firearm clearly depicting the firearm and its newly engraved serial number to your existing USNA via the CFARS. By uploading the four digital images to your USNA, you will complete the USNA process.

The following additional information shall be engraved, cast, stamped (impressed) or
permanently placed on the receiver, frame, or barrel:

1. The model of the firearm, if such designation has been made;
2. The caliber or gauge of the firearm;
3. Your first and last name as provided to the Department for recording
purposes; and
4. The city and state (or recognized abbreviation thereof) where you
manufactured or assembled the firearm.

Please upload the digital images as indicated below to your USNA via your CFARS account:
1. One digital image shall be a close-up image of the engraved, cast, stamped
(impressed), or permanently placed unique serial number and additional information, which
shall be located on the receiver or frame of the firearm. This image shall encompass the
entire unique serial number, so the Department can easily read it when it reviews this image.
2. One digital image shall depict the entire side of the firearm. This image
shall be photographed horizontally and taken directly from above in a way that captures the
entire firearm. The image shall encompass either of the following:
(A) If it is a long gun, the image shall capture everything from the end
of the barrel to the end of the stock; or
(B) If it is a handgun, the image shall capture the handgun from the
point furthest from the end of the barrel to the opposite end of the handgun; or
(C) If it is a receiver or frame only, the entire firearm shall be depicted.
3. The other two digital images shall show the left side of the receiver or frame
and the right side of the receiver or frame. These locations are typically where firearms are
marked when manufacturing is complete.

I have this email from the DOJ

Unfortunately, pursuant to California Code of Regulations, title 11, section 5474.2, we are unable to use a customized serial number that may have been engraved on your firearm. The serial number must be one that is assigned by the Department of Justice. It is not required to remove the customized serial number that you have engraved on your firearm nor is it required to label each engraved serial number.

I got mine kicked back for listing MULTI as caliber.

I got mine kicked back for listing MULTI as caliber.

Was this during the application process or after it was engraved?

[sbo80]

other types of registrations also have been kicked back for "multi". It's not in their dropdown as an option. "firearm with interchangeable barrels" is. I successfully did a "new resident handgun" registration when I moved here of a factory AR with "multi" engraved but 5.56 as the caliber, as was stamped on the barrel. The first application they rejected "multi".
I disagree with the "remove the old serial is a crime" advice. For an 80%, I don't think ATF would consider a set of numbers to officially be a serial unless it's used on a 4473 or in a bound book, the same was it is for an FFL when they manufacture. If the FMBUS number is the registered number, the other number is just decoration.

You think, but you don't know. Nobody knows. Anyone can take that gamble if they want to. It's cheaper and easier not to, though.

I’m leaving everything on there at this point.
Just wondering if I should stamp a “Caliber: 556” on there for good measure even though it already says ‘multi’ - I probably will since it’s just on one of them.

My 80% ARs won’t be winning any beauty contests - it will be joke really with all that bs on the side now but at least they will run.

[CandG]

I wouldn't bother. If it says multi on the receiver, then select "firearm with interchangeable barrels" and call it a day.
