Incorporates the 510 iris.Iris adjustable over a wide range of 0.5 - 3.0mm Two separately adjustable polarisation filters.Our Gehmann polarization filters offer two key advantages that lead to noticeably better and longer-lasting performance of the aiming eye. Light oscillations ("flicker") can be filtered so that only specific oscillation directions pass through the polarizing filter. By engaging a polarizing filter in which special quartz crystals are embedded, the so-called reflex rays are eliminated. By switching on the second polarizing filter, the position of the quartz crystals relative to each other can be changed so that they achieve a 10 to 90%, continuous, light absorption (changed brightness).Can be used as an iris only - or with one, or both, polarisers.Locking collar allows precise location of the V-mark.Removable steel threaded connector for the opportunity to add, for example the 0.0 dioptre.Light reflection is kept to a minimum by applying a special matt finish to all external and internal surfaces.Laser engraved indications.Thread M9.5x1 for all well-known target rifle brands.Instruction manual included.
