Nicole, yes this has a serial number and can be shipped to CO. Have a great day!

Nichole, yes since this is serialized it is perfectly legal in Colorado and can be shipped. Hope this helps.

Nicole, yes it can to most Zip Codes if Serialized. As of 1/4/2022, the city of Denver prohibits so-called “ghost guns,” defined as
privately-made firearms with no serial numbers or markings. This includes prohibiting
the possession, carrying (open or concealed), wearing, flourishing, use, or
manufacturing of non-serialized firearms (including any non-serialized frame or
receiver). ----------------- Details here : budsgunshop.com/feeds/state_reg/colorado_restrictions.pdf
