A later UK light tank using a ranging gun is the FV101 Scorpion, which uses a 7.62mm L43A1 machine gun. This is mounted as a normal co-axial machine gun and may be used as such. it is a development of the standard British L8 Tk MG, used on a number of AFVs and Artillery Pieces. It has an additional barrel bearing that is used to mount the gun. This bearing, rather than mounting by the receiver as for the L8, gives a more consistent point of impact between a cold and hot barrel, which is important for use when ranging.
