Frequently Asked Questions

What are the mandatory engraving requirements for NFA Form 1 items?

For NFA Form 1 items like SBRs, SBSs, AOWs, and silencers, you must engrave the entity name and city/state of the new manufacturer. The engraving must be legible, at least 1/16th inch tall and 3/1000th inch deep.

What are the best methods for engraving NFA items?

Modern laser engraving is highly recommended for its precision and efficiency, especially on harder materials like steel. While mechanical engraving and hammer stamping are options, they are less precise and can be more difficult.

Where can I legally place NFA engravings on my firearm?

Engravings must be visible with the firearm assembled. Creative placements include the inner lip of an AR-15's magwell (visible when the magazine is removed) or inside a revolver's crane.

Do I need to engrave the caliber on an AR-15 receiver for a Form 1 build?

No, you generally do not need to engrave the caliber on the receiver of a multi-receiver AR-15 platform. If the barrel is already marked with the caliber, this typically satisfies the requirement.
