What Are the Assault Weapon Laws in South Dakota?
Woody's answers are based on published federal and state law. Not legal advice. Consult a licensed attorney for your specific situation.
South Dakota has no state-level assault weapon laws or bans. The state follows federal regulations only, meaning standard semi-automatic rifles are legal to own, build, and possess without additional state restrictions.
What This Means for You
For builders in South Dakota, this means you're only dealing with federal compliance requirements like the National Firearms Act for short-barreled rifles or suppressors. The state doesn't impose additional magazine capacity limits, feature restrictions, or registration requirements beyond what federal law mandates. This regulatory environment gives builders significant freedom in rifle configurations and modifications.
The Detail
South Dakota takes a hands-off approach to firearm regulation, particularly regarding what other states might classify as assault weapons. The state has no laws defining or restricting semi-automatic rifles based on features like pistol grips, adjustable stocks, flash hiders, or magazine capacity. This means you can legally own and build AR-15 style rifles, AK variants, and other semi-automatic platforms without worrying about state-specific feature compliance.
The absence of state assault weapon laws means South Dakota residents only need to comply with federal regulations. This includes NFA requirements for short-barreled rifles under 16 inches, suppressors, and fully automatic weapons manufactured before 1986. Standard capacity magazines of any size remain legal at the state level, though you should verify current federal regulations regarding imports or specific manufacturer restrictions.
South Dakota also doesn't require registration of firearms or special permits for owning semi-automatic rifles. The state's approach aligns with its general philosophy of minimal firearm restrictions, making it one of the more permissive states for gun owners and builders. However, federal laws still apply, so ensure compliance with ATF regulations on any modifications or builds.
While South Dakota law is permissive, always verify current federal regulations and any local ordinances that might apply in your specific area. Some municipalities could theoretically have their own restrictions, though this is uncommon in South Dakota. Check with official state resources or consult with a local FFL dealer familiar with current regulations.
Build Impact
You can build pretty much any semi-automatic rifle configuration you want in South Dakota without state-level restrictions on features or magazine capacity. Just ensure your build complies with federal NFA requirements if you're going with short barrels or adding suppressors.
