Colorado law in detail

  • Partial (local) Assault Weapon Ban — There is no statewide assault weapon ban, but Denver and some localities ban assault weapons within city limits.
  • Partial (State Preemption) — The state preempts most local gun laws, but Denver and a few other localities retain some regulatory authority, including assault weapon bans.
  • Yes (semi-autos, since Aug 2026) Permit to Purchase — Since August 1, 2026, buying most semi-automatic firearms with detachable magazines requires a sheriff issued eligibility card and a firearms safety course. A federal challenge is pending.

The federal rule

There is no federal assault weapon ban; the 1994 federal ban expired in 2004. States that restrict them either name specific models or define an assault weapon by features such as a pistol grip, an adjustable stock, a flash hider or a threaded barrel, which is why featureless and fixed magazine builds exist.
