to an Allison MT-653 transmission. The original 75 mm Gun M6 L/39 was replaced with a French D-925 90 mm low pressure gun, with a co-axial 0.50-inch (12.7 mm) M2 heavy machine gun. The bow gunner position was eliminated in favor of ammunition stowage. A new fire-control system was installed, complete with a Simrad LV3 laser rangefinder. Norwegian firms also converted eight M24 light tanks into light armored recovery vehicles to support the NM-116. The NM-116 were retired from service in 1993. Other variants The Chilean Army up-gunned their M24s in the mid-1980s to the IMI-OTO 60 mm Hyper Velocity Medium Support (HVMS) gun, with roughly comparable performance to a standard 90 mm gun. Chile operated this version until 1999. Uruguay continues to use the M24, modernized with new engines and 76 mm guns which can fire armor-piercing, fin stabilised, discarding sabot (APFSDS) rounds. In the mid-1950s, in an attempt to improve the anti-tank performance of the vehicle, some French M24s had their turrets replaced with those of the AMX-13 light tank. AMX-13 variants with Chaffee turret also existed.
