Adjustment Of The Scope On The Rifle - Dedal-NV 450 Operation Manual

reticle by turning for one click at the distance 100m is 15mm (½ MOA). The dimensions
are indicated in meters at 100m distance.

Adjustment of the scope on the rifle

Before the adjustment of the scope its objective should be adjusted for a distant object
(select infinity) in a dark time with the opened cover of the objective.
Adjustment of the scope can be performed in a daytime with the closed cover of the
objective or in the twilight on the adjusted target or on the remote point.
Adjustment of the scope is performed in the following way:
– fix the scope on the fit of the rifle;
– set a panel with a target or select the point of aiming;
– set the rifle on the scoped machine;
– direct the rifle to the point of aiming by mechanical
sight (bead with a slot) (if it is possible). At this stage it is
suitable to apply laser of cold test shooting inserted in the
barrel of the rifle, which indicates geometrical point of the
barrel position. Such lasers are supplied by the JSC Dedal-
NV;
– unscrew the protective caps of the bias screws of the aimed graticule. Turning the
bias screws of the reticle obtain the matching of reticle crosshairs with the aimed point,
set by the mechanical sight or cold test shooting
– remove the rifle from scoped machine and take out cold test shooting;
– make 2-3 shots. Having examined the target make necessary corrections (for
example, in order to move the hit point downwards and leftwards, screws of the
mechanism should be turned clockwise, in the directions Down and Left
correspondingly. The aiming point is moving upwards and rightwards);
– make a control shot and find out whether the aiming point coincides with the bullet
hit point. (Make the correction again if necessary);
– the shoot in position of windage/elevation mechanism could be set in a zero
position. For that end you should unscrew three screws of the knob with allen key (not
included in the standard set) and turn the knob until the zero position of the knob
coincide with special mark on the body of the scope. Use the same key to fix the
elevation knob with three screws.
– fix the protective caps
– the device is ready for operation;
Note.
In view of speciality of manufacturing technique and design of vacuum technique, it
is not always possible to eliminate all hidden defects, which could appear during
impulse load when shooting. It is recommended to make 10-15 shots during
adjustment fire to make additional control before real operation.
