摘要： An open-framework receiver cannon (10) comprises a barrel (12) and a breech ring (20) mounting the barrel. Intermediate regions of two elongate, rigid tubular support members (14, 16) are received through opposite sides of the ring (20) with longitudinal axes parallel to, equally spaced to sides of, and coplanar with, a barrel bore axis (52). Forward ends of the members (14, 16) are rigidly interconnected with the barrel (12) by a barrel support (22); rearward ends of the members are rigidly interconnected by a detachable recoil buffer (18). Disposed in the members (14, 16) are drive springs (192) for driving an associated bolt assembly (26) forwardly on unsearing, recoil apparatus (46) for causing recoil of a bolt carrier (152) in response to firing to enable unlocking of a bolt (154) from the breech (20) and a plurality of inertia weights (270) for reducing bolt carrier bounce from the breech block (20) on forward impact. Recoil cylinders (28, 30), containing a number of springs (300, 302), are mounted around the members (14, 16).
