Frequently Asked Questions

What information must be engraved on a Form 1 NFA item?

Under NFA regulations for Form 1 items, you must engrave the manufacturer's name and the city and state where the firearm is manufactured. If you are converting an existing firearm, you may also need to include the original manufacturer's information.

What are the minimum size and depth requirements for NFA engravings?

The ATF mandates that NFA engravings must be at least 1/16th of an inch in height and 3/1000th of an inch deep. The engraving must also be legible and permanently marked on the firearm.

Where can I place the required NFA engraving on my firearm?

The engraving must be visible with the firearm assembled, but you have flexibility in placement. Common locations include the receiver, magwell (inner lip), or inside the firearm's frame, depending on the firearm type.

Is laser engraving the best method for NFA markings?

Laser engraving is generally recommended for NFA markings due to its precision, speed, and ability to engrave various materials like steel, aluminum, and brass effectively. It offers a cleaner and more durable mark than older mechanical methods.
