The CN120-25, also simply referred to as Modèle G1 (G1 model) is a French smoothbore 120mm tank gun of 52 calibers designed by the EFAB of Bourges for the export market.
Description[]
Designed by the Établissement d'Études et de Fabrication d'Armements de Bourges (EFAB), the G1 120 mm smoothbore gun has been designed to be interchangeable with the rifled 105 mm CN 105 F1 tank gun. The G1 uses semi-combustible propellant cases and has been designed to fire both French-produced ammunition and German Rheinmetall-produced ammunition.[1] A vertical sliding breech-block is used, the barrel is chrome-plated and autofrettaged.
The 120 mm smooth-bore gun G1 has been fitted to the privale venture Giat Industries AMX-32,[2] AMX-40 and the Brazilian ENGESA EE-T2 Osório main battle tanks, neither of which entered production. This weapon was previously referred to as the CN120-24 gun.
