DESCRIPTION OF ASSEMBLIES
Assembly 1  Receiver with barrel, cocking mechanism and sights
The receiver connects the barrel, cocking mechanism and sights.
In addition, all assemblies are either contained in the receiver or attached
to it (Fig. 7).
The barrel is press-fitted into the barrel extension and fixed in place by
means of pins. The cocking mechanism is located above the barrel and
is employed for manually cocking and loading the weapon and for
securing the bolt in its rearmost position.
The sights consit of the front sight and rotary rear sight. The rear sight
has 4 aperture positions; the apertures, which differ in diameter, all
correspond to a uniform sight setting (sighting shot) for firing at ranges
of 25 and 100 m. Being able to select a particular aperture diameter
permits perfect individual aiming by means of the rear sight aperture,
front sight and the outer circumference of the front sight cover.
The rotary sight can be adjusted for elevation and windage.
