The short-barreled rifle, or SBR, is given to any shoulder-fired rifled firearm in the United States that has a barrel length of 16 inches or shorter or an overall length of 26 inches or shorter. The BATFE regulates SBRs as a Title II weapon. If a person meets all requirements and is in accordance with local laws, a citizen is allowed to own at SBR providing they pay the $200 tax for possession of the weapon.
The overall length is determined by measuring between the extreme ends of the weapon, along the centerline that passes through the barrel’s center. Guns with folding stocks must be measured with the stock in intended firing position. The length of the barrel is typically measured by inserting a measuring device into the barrel and measuring from the end of the muzzle to the front of the breechface.
SBRs can be created by trimming a larger rifle down in length or by building a rifle with a barrel shorter than 16 inches. They can also be created by adding a shoulder stock to a handgun that has a barrel less than 16 inches. This would legally change the gun’s status from handgun to a short-barreled rifle. The possession of a SBR must be approved by BATFE and the weapon must be registered with their database. Certain handguns that qualify for SBR status that were produced before 1946 are typically regarded as relics and have been remove from federal SBR restrictions.
