Its a good sight, but there is a change coming, and that is the sight will be mounted on the RH side, vice the LH side. Its supposed to be different too, but I have only seen it once on the new V3 , A3 or G3, the newest of ADI 'prototype' of F88, depending on who calls it what. DMO Melbourne says the changes are coming.
The big change on the sides issue is the weapon generally is always placed cocking handle down, as to ensure the safety catch can be seen on, and the rifle is often stepped on, and damaging the sight, with it placed on the RH side, it elliminates the problem.
We are having many bent sights, and even though if it is still moved to the RH side, the problem of breaking cocking handles will not change. They are cast, and very weak, and easily broken off, so you literally cannot cockk the weapon. A very poor design fault, which they (DMO gurus) thought they had licked when the folding cocking handle was introduced, but suddenly taken off the fleet, as with certain NV equipment, the rifle could not be cocked, as the eqpt got in the way. The folding CH was a great idea, and would have pretty much solved the problem.
As for the sight, it takes batteries CR2032, which suppose to last 5 yrs, not. With the humidity and extreme heat up to 50C in the shade, plus, its black, we are getting maybe 12 months out of a battery, and its a prick to change. Little bolts, Allen key type, which can easily corrode, and get stripped.
I do like the idea of estimating the range, setting it, and placing the 'red dot' on target.
Cheers,
