Colorado law requires a background check when an unlicensed seller transfers a gun. See Universal Background Checks in Colorado.
Colorado also prohibits any person from knowingly purchasing or otherwise obtaining a firearm on behalf of or for transfer to a person who the transferor knows or reasonably should know is ineligible to possess a firearm pursuant to federal or state law.1
Colorado specifically penalizes anyone who gives false information in connection with the making a record of a handgun transfer.2 Colorado also prohibits any person, in connection with the acquisition or attempted acquisition of a firearm from any transferor, from willfully making any false or fictitious oral or written statement or furnishing or exhibiting any false, fictitious, or misrepresented identification, but only if the statement or identification is intended or likely to deceive such transferor with respect to any fact material to the lawfulness of the sale or other disposition of such firearm under federal or state law.3
