What Are the Assault Weapon Laws in Wyoming?
Woody's answers are based on published federal and state law. Not legal advice. Consult a licensed attorney for your specific situation.
Wyoming has no state-level assault weapon bans or restrictions. The state follows federal firearms laws only, making it one of the most permissive states for firearm ownership and configuration.
What This Means for You
Wyoming's lack of assault weapon laws means you can build rifles with features that are heavily restricted or banned in other states. You can use standard capacity magazines, install muzzle devices, use adjustable stocks, and build rifles in any configuration that complies with federal law. This makes Wyoming particularly attractive for builders who want maximum flexibility in their projects.
The Detail
Wyoming operates under a constitutional carry framework and has consistently rejected attempts to implement assault weapon restrictions at the state level. The state follows only federal regulations, which means NFA items like short-barreled rifles require federal tax stamps and approval, but semi-automatic rifles can be configured without the feature restrictions you see in states like California or New York.
You can build AR-15 platforms with telescoping stocks, pistol grips, flash suppressors, bayonet lugs, and threaded barrels without any state-level concerns. Magazine capacity is unrestricted at the state level, so you can use standard 30-round magazines or larger capacity options. The state also has no registration requirements for standard firearms, though NFA items still require federal compliance.
Wyoming actually has firearms freedom laws that attempt to exempt Wyoming-made firearms from federal regulation when they remain within state borders, though federal agencies generally do not recognize these exemptions. The state legislature has been consistently pro-gun rights and has shown no indication of moving toward assault weapon restrictions.
For NFA items, you still need to follow all federal procedures including Form 1 submissions for builds or Form 4 transfers for purchases. Wyoming does not add any additional state-level requirements to the federal NFA process, which can make transfers somewhat simpler than in states with additional local restrictions.
Build Impact
You have complete freedom to build rifles in any semi-automatic configuration that meets federal standards. Wyoming's permissive laws mean you can focus on function and performance rather than navigating complex feature restrictions that plague builders in other states.
