The System Gemini Ladder Foresight gets over the problem of poor location for refit after removal by not using a clamping type mechanism, The sight has a sleeve that is permanently fitted to the barrel, a locking ring then clamps the ladder to the barrel, precision flats on the sleeve make sure there is perfect alignment, this makes the sight easy to remove for transportation of the rifle, there is no risk of bending the ladder frame and guarantees return to an exact windage zero.

The sight has been designed to give a round foresight image, this makes the sight easier to centralise, it has a fully threaded tunnel to accept all metric thread foresight accessories both 18mm and 22mm (although some may reduce the lower travel of the ladder foresight.) Because the locking collar for the sight is on the barrel and not on the tunnel, the exact positioning of an ‘Eagle Eye’ is guaranteed, because it is fixed permanently.

The long travel on the ladder allows the sight to be used with Weaver style rear sights which naturally have a higher sight line and on military style rifles with high sight lines, the tunnel also sits very low to the barrel line to give maximum elevation, the sight has 150 minutes elevation.
