Australia   T2 MKV

About
The T2 MK5 came with a Zytel stock and was the semi-auto variant of the select-fire Leader T2 MK3.

Less than 2,000 total rifles were imported into the United States. The import dates are shown in various places as 1986-1989, but Leader sold the designs to AAA in 1983 which made a few small changes as well as renaming the firearm the SAR.
