The Yanks have got them on their M240B's (ELCAN M145 series), and we use various types of optics on the MAG 58 and the LSW (C79), but the LSW comes standard with the same otpics as the F88SA1 has.
I know that our so called gurus in the small arms field share alot of info with Canada (I have seen CFTOs and many of the F89 parts have CF NSNs ( op rod for example), and some gauges for inspection are infact Diemaco made (firing pin protrusion gauge for example, it too has a CF NSN right on it), plus I seen some 1982 Ptrn CF spare bbl carriers for the C9, but we developed our own instead in yes, AUSCAM.
Keeping things simple, the optics here are ADI designed, and very robust and durable. Only a 1.5X magnification, with a 'donut' and cross hair as a sighting picture.
Commercially, these optics can be purchased for about $US400.00, as I have seen them advertised occasionally in the USA, etc.
You'll note that the Aussie weapon has no iron sights at all, as the front sight is not even milled for on the gas block, and there is no rear sight at all period. However the optics have an emergency sight on top, and white dots are used for low light etc on them.
I am in the armoury all day tomorrow, and I'll post some new pics after work tomorrow.
Cheers,
