    5. INSTALLATION ON A RIFLE 5.1. Installation with thread usage Your NVS-33 matches to the inner thread M52x0.75 of the objective lens of those daytime riflescopes that can accept daytime filters. If your scope does not match this thread, use mechanical adapters that transform M52 into M54, M55 or M48 threads.
  • Page 13 The manufacturer is not responsible for use of NVS-33 night sight attachment by a threaded connection on the scope models other than those, which were approved by Newcon Optik. There is no need to re-zero daytime scope or perform any additional adjustment when NVS-33 is installed on the rifle.

  • Page 16 Assemble the adapter and mount the night sight attachment as follows (Fig. 3): 1. It’s necessary to select needed quantity of the plastic inserts (6) for a particular external diameter of the objective lens of the daytime riflescope. The objective lens of the daytime riflescope (7) should fit loose, but without apparent drift into the adapter (4) with the installed inserts (6) and loosen adapter screw (5).
  • Page 17 The lens of the daytime scope must be positioned at least 15 mm behind the front edge of the scope body. This excludes mechanical contact of the NVS-33 night sight attachment and daytime scope objective lens. Last digits in the NC540 adapters part numbers correlate with the diameter of the daytime riflescope.

    5.3. Installation on a Picatinny rail The night vision attachment NVS-33 can be installed on a Picatinny rail in front of the daytime riflescope. For this purpose, it has an additional Picatinny rail on the side. Night sight Picatinny rail Fig.
  • Page 19 Quick release Night sight rail Fig. 5 rifle rail clamp clamp with screw Actual height of the adapter must be determined at the moment of ordering of the Picatinny rail adapter. Each rifle and riflescope combination is unique, and it is necessary to know height of the line of sight above the Picatinny mount to produce this part precisely.
  • Page 20 Distance between NVS-33 line of sight and daytime riflescope line of sight must not exceed 2 mm. In case of two different rails are used, the angle deviation between two rails must not exceed 2 degrees. Picatinny rail adapter is attached to the scope permanently by means of a small clamp and screw.

  • Page 25: Operation At Night

    6.5. Operation at night Operation procedure: 1. Check the adjustment of the daytime riflescope (diopter adjustment, parallax adjustment, etc.). 2. Install the battery into the NVS-33 and mount it in front of the daytime riflescope as described above. Being mounted in front of a daytime riflescope, the night vision riflescope attachment NVS-33 keeps all tactical features of a daytime riflescope (zoom level, adjustment step, etc.) intact.
  • Page 26 In order to get the maximum quality of night picture through the daytime riflescope, we recommend using riflescope magnifications from 3 to 12. 6. Aim the rifle to an object and focus the objective of device with the knob (7) (Fig.1) on its top until you get maximum sharpness of the observed picture.
  • Page 27 If necessary, turn on the IR-illuminator (6) (Fig.2) (Special order only). NVS-33 is protected against accidental illuminator switch by the design of the switch handle. Press and rotate the switch (5) (Fig.2) to activate the illuminator. Divergence of IR beam could be changed from 5 to 20 degree by rotating of the IR lens.
  • Page 28 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.
