Depends on the gun. A rifle or shotgun that is unloaded MAY be mailed in the US Mail. See Domestic Mail Manual, section 14, restricted mailings. A handgun may only be mailed by a licensed dealer or manufacturer. If the OWNERSHIP of the gun is changing, other than by inheritance, and it is going to another state, the gun must be sent to a licensed firearms dealer in the state of the receiver of the gun.

You can ship everything except the action through normal shipping channels. The proper way to ship a firearm is between FFL (Federal Firearms Licensee) holders. These are usually gunsmiths, or firearm retailers. Barrel, frame, grips, slides, hammers, triggers, sears, springs, firing pins, etc. can all be shipped normally, through USPS or UPS, or the transport service of your choice.

The rate for USPS flat rate envelopes through Priority Mail International is $19.95 to Canada. Depending on how much weight you are shipping, it may be significantly cheaper to ship through standard mail.
