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.

Assembly 4 Butt stock
Fixed butt stock
The fixed butt stock (Fig. 17) closes the rear of the receiver. It is conÂnected to the receiver by a locking pin.
The sling holder is attached to the butt stock by means of tubular rivets,
which are also employed for safekeeping of the locking pins when the
weapon is field stripped.
Retractable butt stock
The fixed but stock can be replaced by a retractable butt stock (Fig. 18)
when required.
The two guide rails on either side of the butt stock are guided in grooves
on the receiver. They are secured by a locking catch in both the retracted
