Federal law requires that a shotgun have a minimum barrel length of 18" and a minimum overall length of 28". Colorado law is not more restrictive.
Yes, it meets the minimum overall length requirements. Since it is a single shot there is no minimum length required for the barrel.
The legal minimum length of a non-rifled gun barrel in the united states is 7 inches.
It can be, depending on the action the gun uses. It can also be illegal if you cut the barrel length below the legal limit. In the US, a Title 1 rifle must have a minimum barrel length of 16 inches, and a Title I shotgun must have a minimum barrel length of 18 inches.
The usual minimum length is 18 inches measured from the face of the closed bolt. It is possible to own and possess a shotgun with a shorter barrel, but this requires obtaining a federal tax stamp ($200). Also shortening the barrel causes a loss of accuracy and a reduction in velocity of the shot.
Depends on what you want to do with it and if you want to go to the trouble of getting the appropriate federal approval.
Must be a minimum of 26 inches in length, with a barrel no shorter than 18 inches. That's federal law.
