Terms of Service and Disclaimer

Why does this site exist? was launched in 2003 by Rocky Mountain Gun Owners to restore Coloradoans’ ability to exercise their right to gun ownership and transfer. There have been many insults and barriers erected in regards to this right. The most obvious is the decision by Colorado’s major newspapers to cease accepting classified ads for firearms. They won’t let you place firearm ads there in exchange for your hard-earned money - so RMGO is giving our members the ability to place unlimited firearm ads online.
