Abstract: A modular concept for a gun which uses a breech conversion kit allows the firing of cased and caseless ammunition with the same gun. The cannon has 2 breech mechanism (10) which includes a first sliding breech-block (19) which engages the rear end (15) of a cartridge case in the firing position. Said first sliding breech-block (19) is interchanged for a second sliding breech-block (21) when firing caseless ammunition. Said second breech-block is in contact with a scaling member (23) which is mounted pivotally on an axis (27) which is located on the upper face of breech ring (11).
