Yes. You are allowed to have a suppressor on your gun while traveling, but you must have the appropriate paperwork and permits.
A suppressor, also known as a silencer, is a device that attaches to the barrel of a firearm to reduce the amount of noise it makes when fired. While they are not illegal, they are heavily regulated by the federal government. To possess or use a suppressor, you must first obtain a special permit from the Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF).
