The scope body is sealed and filled with nitrogen, which prevents fogging of optics and was designed to function within a -50 °C to 50 °C temperature range. For zeroing the telescopic sight the reticle can be adjusted by manipulating the elevation and windage turrets in 5 centimetres (2.0 in) at 100 metres (109 yd) (0.5 mil or 1.72 MOA ...
