NFA Engraving Requirements: What the ATF Requires and Why
Updated March 2026 | By Horace Firearms
If you\'re building an SBR, SBS, or suppressor on a Form 1 — or registering an NFA item under a trust — the ATF requires specific markings to be engraved on the firearm. Get it wrong and you\'ve got a compliance problem. Get it right and it\'s one less thing to worry about.
Here\'s everything you need to know about NFA engraving requirements — what to engrave, where to put it, how deep it needs to be, and when it\'s required.
When Is NFA Engraving Required?
NFA engraving is required in two main situations:
Form 1 Builds — When you manufacture an NFA firearm yourself. This includes building an SBR (Short Barreled Rifle), SBS (Short Barreled Shotgun), or a Form 1 suppressor. You can have the engraving done at any time — before or after your Form 1 is approved. Many people get it done while they're waiting for approval so they're ready to go as soon as it comes back.
Trust Registrations — When an NFA item is registered under a gun trust, the trust name (not your personal name) must be engraved on the item along with the city and state.
What Information Must Be Engraved?
The ATF requires the following information to be permanently engraved on the NFA item:
✓ Maker\'s name — Your legal name if filing as an individual, or the trust name if filing under an NFA trust
✓ City — The city where the item was made
✓ State — The state where the item was made
Example (Individual): John Smith, Fargo, ND
Example (Trust): Smith Family Trust, Fargo, ND
ATF Depth and Size Requirements
The ATF has specific technical requirements for the engraving itself. These are not suggestions — they\'re legal requirements:
0.003\"
Minimum Depth
1/16\"
Minimum Text Height
The engraving must be at least 0.003 inches deep and the text must be no smaller than 1/16 inch (0.0625 inches) tall. At Horace Firearms, our laser engraving meets and exceeds these specifications on every job.
Where Should the Engraving Be Placed?
The markings must be placed on the frame, receiver, or barrel of the firearm. They must be conspicuous — meaning visible without disassembling the gun.
For AR-platform SBR builds, the most common placement is on the lower receiver — typically on the magwell area or the flat space near the selector switch. We\'ll help you pick the best spot based on your specific build.

Common Mistakes to Avoid
Waiting until the last minute to get engraved
You can get your engraving done at any time — you don't have to wait for your Form 1 to be approved. A lot of people bring it in while they're waiting so it's ready to go the moment their approval comes back.
Using your personal name on a trust-registered item
If the item is registered under a trust, the trust name goes on the engraving — not your personal name. This is a common mix-up.
Engraving too shallow or too small
Hand engraving or cheap engraving tools might not meet the 0.003 inch depth requirement. A professional laser engraver ensures compliance every time.
Hiding the engraving under a handguard or accessory
The markings must be conspicuous — visible without removing parts. Placement under a rail or handguard doesn\'t meet the ATF requirement.
