PK Series Manual (English, 2005) - Forgotten Weapons

Rear Sight Assembly. The rear sight assembly (see figure 1-30) consists of the base,
leaf, elevation knob, leaf spring, and sight bar assembly. The sight base is riveted onto
the receiver cover. On the front of the sight base there is a projection which fits through
the longitudinal rectangular slot in the receiver cover and functions as the cartridge stop.
The top of the base is cut through in order to hold the leaf spring. The leaf and elevation
knob serve to set the firing range. The upper surface of the leaf has an engraved scale
with divisions representing values of 100 meters, in marks numbered 0–15. The “0”
mark is used when engaging targets in the air.
The lower right side of the leaf is serrated to fit the tooth of the knob fastener. On the
front of the leaf is the sight bar slot, which on the rear surface has a scale from 0–16
mils, on which each mark has a value of 2 mils (0–02). The elevating knob consists of
the shank, fastener, and spring. The fastener has a tooth, which the spring presses into
the notches on the right side of the leaf. The sight leaf spring is housed in the base and
holds the leaf in the desired position by pressing its rear edge upward.
