I looked around....and found a couple things. First off I am in Denver city and county. I saw that the Colt AR-15 was banned by name. As well as assault...eh hem....sporting rifles with mags over 20 rounds. Can anybody verify this? Just looking to remain in the confines of the law while still being able to get what I need out of the weapon. Looking at various weapons but no COLT ARs. Please confirm or advise. Thanks.
