This 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 centralize, and it has a fully threaded tunnel to accept all metric thread foresight accessories both 22mm and 32mm. 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 Picatinny/Weaver Rail mounted 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 60 minutes of elevation movement.
A Rain Guard Kit is also available as an upgrade. This is available for both the front light tube and rear light tube. It is easily disassembled for cleaning.
The barrel sleeve fitting is common for both 22mm and 32mm sights.
In all cases the complete tunnel assembly can be removed for safe transportation or storage.
There have been problems with the Centra 32mm Irises when the rear light tubes have been fitted. The installation of the rear light tube requires the removal of the knurled ring on the back of the Iris so that the light tube may be screwed on. The recoil shock of fullbore rifles can cause another locking ring in the rear of the Iris to unscrew. This was originally prevented by the knurled ring (the one removed for the rear light tube) which has a flange. Unfortunately, the light tube does not have a flange inside so the locking ring can come out allowing the Iris to fall apart. Through the quick action of Centra GmbH, we now have available a ring which is inserted between the Iris and the rear light tube to prevent these problems from occuring in future.
If you have an HPS 32mm Foresight and are using a rear light tube, please contact us for one of these rings.
