Abstract From the Canadian patent
Disclosed is a gun barrel disposed within a barrel shroud. The rearmost ends of the shroud and barrel are supported in the gun frame and the opposite end portions of the shroud and barrel are interconnected and mutually supporting. A barrel support ring is disposed intermediate opposite ends of the barrel and includes an aperture for receiving the barrel and margins resiliently bearing against the inside surface of the shroud to provide a friction fit. The barrel ring supports the intermediate portion of the barrel within the shroud and prevents loss of straight-line dimension along the length of the barrel.

Why it's free to use

- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
