The reticle is adjusted with tuning knobs situated
on the upper and right side surface of the body. A
vertical and horizontal correction of reticle is of 60
MOA, and one click moves a reticle by 0.5 MOA. The
knobs are protected with metal screw caps which
protect against an accidental switch of connected
with a casing with steel string due to which they
are protected against getting lost.
The LDK-4 sight is compatible with thermal
weapons sight and night vision devices installed in
front of the sight that enable using it at night or
under reduced visibility conditions.
A MK-1 is 1x magnification micro red dot sight with
3 MOA dot. It is powered with one CR2032 battery,
which – in normal operation at temperature of
15°C – ensures not less than 500h of continuous
work of the collimator. The MK-1 has a possibility
of adjusting during test-firing within a scope of +/-
60 MOA in the vertical and horizontal plane. For
making adjustments are two mini-screws situated
on the upper and right side surface of the casing in
the manner that precludes their accidental turning.
A lighting intensity level of the reticle is adjusted by
buttons located on the rear side of the casing (from
the shooter side), which are also for turning on and
off the sight. Weight of the MK-1 without a battery
is up to 70 g.
In the older version of the CKD-1 combo, the MK-1
was assembled above the eye-piece, but during
preliminary tests it turned out that it collides with
a helmet visor, therefore in the new version of the
CKD-1 it was added a front attachment for the
micro sight. Now it can be assembled above an
eye-piece or just behind an object-glass.
