Short-barreled rifles (SBRs) and short-barreled shotguns (SBSs) are NFA items that require the same ATF approval process as suppressors. Dealers who stock and sell these items need to understand the specific compliance requirements.

What Makes a Firearm an SBR or SBS

A rifle becomes an SBR when its barrel is less than 16 inches, or its overall length is less than 26 inches. A shotgun becomes an SBS when its barrel is less than 18 inches, or its overall length is less than 26 inches.

Configuration matters more than intent. A rifle with a 14-inch barrel is an SBR regardless of why it was configured that way. Dealers who take in consignment or trade items need to measure and classify what they receive — not assume classification based on what the consignor tells them.

Form 4473 for SBR/SBS Transfers

The firearm description section requires the make, model, caliber, barrel length, and overall length to be recorded. The classification as a short-barreled rifle or shotgun should be reflected in the firearm type designation on the form.

Pistol-to-SBR Conversions

Customers who want to add a rifle stock to a pistol are creating an SBR that requires ATF approval before the conversion. Dealers should not facilitate a pistol-to-SBR conversion without verifying that the customer has received ATF approval for the SBR.
