History / Summary

This rifle was used by the Australian Special Air Service Regiment when they had the responsibility for urban counter terrorist operations in the 1980s. Marksmen of the regiment were issued with two of these rifles, one like this one for day use and another fitted with a night telescope. A number of these rifles were obtained from the British SAS Regiment who used them for the same purpose as the Australian unit. The choice of the high velocity .22-250 smallbore cartridge was to reduce excessive penetration and eliminate ricochets.
