SBR questions

General Firearms NFA
1

I recently picked up a stripped receiver to make SBR out of my LMT MRP. I have used the search and looked at the stickies and still have a few questions.
1 Is the only info that needs to be engraved on the receiver; My name, City, State and caliber?
2 The receiver was registered as 5.56 when I bought it; Can I list more than one caliber on the form such as 5.56 and 9mm?
3 Can the engraving be done on the underside of the trigger cut out?
4 Has anyone used a class 3 dealer to do the application? How much did they charge.
Thanks for any help. I hope to send the receiver out to be engraved in the next month, then start the paperwork.

  1. You need to engrave you name, city, and state. You can use the caliber marking that is already on the lower.

  2. Do not list more than one caliber on the form. It will get sent back with a correction letter. This used to be legal but they put a stop to it. If you want to use more than one caliber, you can send a formal business letter documenting the additional calibers.

  3. Yes as long as it is visible without having to disassemble the gun

  4. They wound charge around $75 to $150. You need to do it yourself so you know what is going on.

  1. Caliber needs to be engraved on the rifle, it’s probably already on the barrel, so you don’t need it engraved again. Typically, after a form 1 you’d engrave the makers name (be it trust or individual), city, and state, exactly as it appears on the form 1.
  2. The receiver isn’t ‘registered’ as any particular caliber, you don’t need to list any additional calibers on the form 1. Actually, if you list more than one, they will reject it. Just put whatever caliber you plan on building the rifle in.
  3. The engraving can be done on the barrel, frame, or receiver. ATF will get up tight if it’s not clearly visible on the assembled rifle.
  4. Not for a form 1. For a form 4, most dealers seem to charge between $50 and $100. Do a bunch of internet homework, and do the form 1 yourself. It’s not rocket surgery.

For a different caliber or different barrel lengths,you only need to notify ATF if it’s a permanent change. And even then you don’t have to wait for a response, just send the letter. You may or may not get an acknowledgement.

Maybe this helps clarify the caliber issue…I’ll repost something I posted on another site:

The important part:

[quote]Held, pursuant to 27 CFR 478.92(a)(4)(i) and 479.102(c), ATF authorizes licensed manufacturers and licensed importers of firearms, and makers, to adopt the serial number, caliber/gauge, and/or model already identified on a firearm without seeking a marking variance, provided all of the following conditions are met:

  1. The manufacturer, importer, or maker must legibly and conspicuously place on the frame, receiver, barrel, or pistol slide (if applicable) his/her own name (or recognized abbreviation) and location (city and State, or recognized abbreviation of the State) as specified under his/her Federal firearms license (if a licensee);
  2. The serial number adopted must have been marked in accordance with 27 CFR 478.92 and 479.102, including that it must not duplicate any serial number adopted or placed by the manufacturer, importer, or maker on any other firearm;
  3. The manufacturer, importer, or maker must not remove, obliterate, or alter the importer’s or manufacturer’s serial number to be adopted, except that, within 15 days of the date of release from Customs custody, a licensed importer must add letters, numbers, or a hyphen (as described in paragraph 4) to a foreign manufacturer’s serial number if the importer receives two or more firearms with the same serial number;
  4. The serial number adopted must be comprised of only a combination of Roman letters and Arabic numerals, or solely Arabic numerals, and can include a hyphen, that were conspicuously placed on the firearm; and
  5. If the caliber or gauge was not identified or designated (e.g., marked “multi”) on the firearm, the manufacturer, importer, or maker must legibly and conspicuously mark the frame, receiver, barrel, or pistol slide (if applicable) with the actual caliber/gauge once the caliber or gauge is known.

So…you can reuse the serial number, model, etc…but you have to add your name and location, and the frame/receiver/barrel needs a caliber. “Multi” is not sufficient. If your barrel doesn’t have it, it has to be engraved somewhere.[/quote]

You don’t need to notify them for any caliber or barrel length change in any way. They ask you to, and recommend that you do, but there’s no requirement to do so or penalty for not doing so.

I’ve had 5320.20s approved with different lengths and/or calibers, so that doesn’t even have to match the registry. The only time it becomes any issue at all is if you transfer it on a Form 4. At that point, you can include a letter with the form in case they send it back saying it doesn’t match the registry.
