When mounted in front of the daytime riflescope, night vision attachment NVS-33 can change zeroing as not more than 3 cm at 100 m. This is connected with changes in the weapon balance, light distortions in the image intensifier tube, technological limits of the adjustment of the night riflescope attachment. This imprecision usually appears as fixed value and can be easily compensated by the adjustment mechanism of the daytime riflescope.

We recommend you to make 10-15 shots with the mounted NVS-33 before practical using it in field conditions. Such test will check NVS-33 by a real shooting impact and thus will increase reliability of the whole system.

DO NOT FORGET TO TURN OFF THE NIGHT VISION RIFLESCOPE ATACHMENT AFTER USE!
