Can you us a cross bow in Colorado?

In part through the Louisiana Purchase.

Across bow is a bow! It is not a traditonal bow in that you shoot it like a rifle, but it is a kind of bow. Wether or not you can hunt with them depends on your local state laws as some states will...

technically yes but for a hunter no. if you know they both shoot arrows but different sizes and also you use a trigger like you would on a gun for a crossbow so for hunter no there not the same but...

it's like a bow on it's side, and it does the same thing as a bow... its a medievil weapon used for firing arows by a piece of rope attached to a flexable piece of wood then attached to a pullback...
