F88T Austeyr (.22 Steyr AUG)

[imschur]

The F88T Austeyr was developed by ADI Limited (now known as Thales Australia).  It is, as far as I know, the only variant of the Steyr AUG chambered in .22 Long  rifle. A page on the, now offline, ADI website described the weapon as:

ADI has developed a .22 calibre training rifle for use by the Australian Army.  The weapon provides an economical training alternative, with very low ammunition  cost, which can be used in environmentally sensitive training areas and indoor  areas for special force training with reduced risk to trainees and instructors.
