SBR (Short-Barreled Rifle)
A Short-Barreled Rifle (SBR) is a firearm that has a rifled barrel shorter than 16 inches, or the overall firearm length is less than 26 inches. Due to its compact size, it is easier to handle and conceal but is subject to stricter regulations under law. In the United States, owning an SBR requires registration with the ATF, approval of a background check, and payment of a tax stamp. These restrictions aim to regulate firearms that are more easily portable and potentially more concealable, balancing personal use with safety considerations.
