Long shanked tommy bar for our ultralight 8mm (M6 thread) outside hex nut. If you have the weapon in a vice with the tang pointing upwards a handy tip is to use a small piece of Sellotape to hold the nut in the spanner. This Sellotape will prevent it from falling out when you turn the spanner upside down in order to insert it into the handle. Please note this spanner will not fit inside an Aluminium pistol grip. It can be used with our Carbon Fibre and Mag Tech grips.
