2.1.2. INSTALLATION ON MIL-STD-1913 RAIL

NOTE
The optical axis of the PS-40 and the riflescope should be
matched. Difference of the axes position more than 3 mm is not
recommended. Measure the height of the riflescope axis above
the rail. Observe Table 1-2 for the sight axis height above the rail.
If the difference in the axis heights of the PS-40 and riflescope is
more than 3 mm it is necessary to replace riflescope mounting
rings or monoblock by proper ones.
