Abstract
A breech/receiver assembly for automatic cannon incorporates a rotating chamber and a recoil and counterrecoil buffer integrated within the breech. The breech, including the buffer means, recoils with the barrel and because the mass of the buffer is added to the breech and barrel, recoil forces transferred to trunions mounting the breech/receiver assembly are significantly reduced. The configuration of the breech/receiver assembly, including the rotating chamber and integrated recoil/counterrecoil buffer, enables a shorter receiver, thereby enabling a vehicle-mounted cannon utilizing the breech/receiver assembly of the present invention to elevate to high angles while still maintaining a relatively low gun silhouette.
