Does Colorado Have an Assault Weapons Ban?

Statute-cited, last verified 2026-07-10

Legal

No. No assault-weapon feature or configuration ban. From August 1, 2026, SB25-003 adds a purchase-channel permit for specified gas-operated semi-autos, but it bans no feature and no possession.

Litigation Status and Details

SB25-003 (signed April 10, 2025; effective August 1, 2026) requires a safety course and a sheriff-issued eligibility card to buy or transfer specified gas-operated semi-auto rifles, shotguns, and handguns with detachable magazines. It restricts the purchase channel only: there is no possession ban, no registration requirement, and no feature-configuration ban, so any feature combination remains lawful to own and build in Colorado.

Federal baseline

There has been no federal assault weapons ban since the 1994 ban expired in 2004; no feature restrictions apply federally to semi-automatic rifles or pistols. The 2023 ATF pistol-brace rule was vacated by the Fifth Circuit and is not enforced, so braced pistols are not SBRs under federal law. Cargill v. Garland (2024) made bump stocks federally legal. Feature bans are entirely a matter of state law.

Scope: State laws restricting semi-automatic rifles, pistols, and shotguns by configuration features: threaded barrels, pistol grips, folding or telescoping stocks, flash suppressors, forward grips, and similar. Magazine capacity limits are tracked as a separate class.
