daytime riflescope. Thus, it is recommended to estimate if adjustment is
required for a night vision sight in combination with daytime riflescope
by bore sighting daytime riflescope with and without night vision
attachment. Value of the required adjustment should be noted in clicks of
the riflescope and shall be used each time when nigh vision sight is being
used.
RECOMMENDATION:
Please make sure that night vision attachment is mounted on the rifle
with the following tolerances related to position of daytime scope axis:
- maximum permissible misalignment of optical axes shall be within ±1
mm in both vertical and horizontal planes
- maximum permissible misalignment of optical axes shall with ±1
degree in both vertical and horizontal planes
Due to manufacturing process and design of image intensifier tubes, it is
not always possible to eliminate boresight alignment of 1MOA at 100 m,
which could appear during shooting. It is recommended to make 10-15
shots during the scope testing as an additional test before operation in
real conditions.
