Short Barrel Rifles: How to Buy & SBR Laws 

Gun ownership is engrained in American history and culture. Each year more than 20 million firearms are sold, and about 1/3 of those are rifles. With an increasing volume of rifles in the hands of responsible gun owners, short-barreled rifle (SBR) ownership has also soared. SBR ownership is expected to see a historic increase in 2023, spurred on by new cartridges optimized for shorter barreled platforms such as 300BLK, 8.6BLK, and 6ARC, the rising popularity of pistol caliber carbines (PCCs), and ATF pistol brace rule updates.

What is an SBR?

A short barrel rifle, commonly called an SBR, is a firearm intended to be fired from your shoulder with a rifled barrel length of less than 16”. SBRs were initially defined and regulated by the National Firearms Act of 1934 (NFA) and are currently overseen by the Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF). An SBR allows for a lighter, more maneuverable rifle which makes them great in certain types of hunting, competitions, and home defense training.  

Fun Fact: The original barrel length was set to be 18”, just like shotguns. However, M1 Carbines used in World War II featured a barrel length of less than 18”, so the regulation changed to make these military surplus firearms legal for returning soldiers and citizens purchasing military surplus firearms.

Are SBRs Legal? 

Yes! SBRs are legal to own for most citizens. Similar to suppressors, short-barreled rifles are categorized as “Class 3” (ATF speak for highly regulated) firearms by the NFA and ATF. You may be wondering, what is required to have an SBR? Factory-built short-barreled rifles require an SBR tax stamp and ATF Form 4 transfer, the same process as purchasing a silencer. You can also elect to build your own SBR by utilizing an ATF Form 1read more about Form 1 specifics.
