The 105 mm Modèle F1 (or CN-105-F1) is a French 105 mm tank gun used with the AMX-30. A shorter version of this gun was also used in the Israeli Super Sherman.
The F1 is fitted with a semi-automatic vertical sliding wedge breechblock, though fitted without a muzzle break. Unlike the similar 105mm L7 tank gun, the F1 uses a compressed air scavenging system instead of a bore evacuator. The recoil mechanism uses two symmetrically opposed hydraulic brake cylinders with a single hydropneumatic recuperator cylinder.
