Loading the rifle
Press magazine catch, and the
magazine will slide out. Insert filled
magazine into the rifle until the
magazine catch engages.
Then retract the bolt all the way
by means of the cocking lever on
the right side of the rifle. The catch
lever located behind the cocking
lever will engage and hold the bolt
open. Depressing the catch lever
slightly will cause the bolt to
snap forward, chamber a round
from the magazine, and lock
into the receiver. The rifle is now
cocked and ready to fire. The
cocking lever does not move
when the rifle is fired.
The cocking lever should not
be held back and prevented
from moving forward when the
bolt closes.

Operating the safety
ll semi-automatic hunting rifles
shown in this booklet, provide
optimum security, thanks to the
striker safety. The safety can only
be engaged when the rifle is
cocked. To put the rifle on safe,
the safety lever must fully cover
the red dot. The safety is off when
the safety lever fully covers the
white dot.
Unloading the rifle
Remove the magazine by
pressing the magazine catch.
Retract cocking lever quickly, tilt-
ing the rifle somewhat to the side
to permit a round that might be
left in the chamber to slide out of
the ejection port into your hand.
Close the rifle and pull the trigger.
The rifle is now unloaded and
uncocked.
Attention!
Whenever having removed the
magazine, check to make sure
that there is no round in the
chamber.

Field stripping
Under normal conditions, it is
only necessary to clean the exter-
nal components of the rifle and to
clean the bore. In the event of
heavy fouling or to remove mois-
ture or water in the rifle, it is ad-
visable to strip the rifle for tho-
rough cleaning. Unscrew the
hexagon socket screw at the end
of the upper receiver all the way.
Remove the upper receiver to the
rear. Remove buffer and recoil
sprin
.
You can now remove the bolt
assembly by passing a screwdriver through the hole for the
screw and forcing the firing pin
forward. It is not necessary to
further strip the rifle for
cleaning (except for the bolt
assembly).

Stripping the bolt assembly
Rotate the bolt head clockwise
one quarterturn, and then remove
it from the locking piece. Finally,
remove locking piece, firing pin
and firing pin spring from the bolt
head carrier by rotating the lock-
ing piece further
To assemble the bolt, proceed in
the reverse sequence. First slide
the firing pin spring onto the firing
pin and insert both into the bolt
assembly. Then press the locking
piece against the firing pin spring
and rotate counterclockwise one
quarter turn. Assemble bolt head
and locking piece as follows:
Place the bevelled surface of the
bolt head beneath the spring-
loaded bolt head locking lever.
Strike the end of the bolt head
lightly with the palm of your hand
to force the bolt head far enough
under the bolt head locking lever
to provide a clearance of 3 mm
(.12 in) between the bolt head
and the bolt head carrier.
Then rotate the bolt head counterclockwise about one half turn,
until the bolt rollers and the cam-
ways in the bolt head carrier are
located at the same level. Then
pull the bolt head away from bolt
head carrier as far as it will go,
so that the rollers recess com-

ttention! When reassembling
the semi-automatic hunting rifle,
do not forget to insert the locking
rollers into the bolt head as
otherwise the shooter's safety
could not be guaranteed and the
bolt system of the rifle would be
completely damaged
Gap between bolt head and bolt carrier
With the bolt in its closed position
-the magazine being detached-
the bottom side of the bolt is
visible through the magazine
well. There must be a very narrow
gap between the bolt head and
the bolt head carrier. You can
determine this, if you can put a
sheet of paper between bolt and
bolt head (see fig., gap >0).
If this gap has disappeared,
please have the weapon checked
by your local gun dealer as this
technical condition would cause
excessive strong recoil forces and
thus damage the bolt system.

Assembling the rifle
Insert the bolt assembly into the
receiver; when doing this, press
in the firing pin and the rollers,
and slide all the way to the front.
Then insert the buffer and recoil
spring into the receiver. Rotate
the hexagon socket screw one full
turn into receiver. Next, slide
the upper receiver onto the re-
ceiver body from the rear until the
collar of the screw is seated
against the recess in the upper
receiver. Tighten screw firmly.
Sights
The sights consist of a hunting
square notch rear sight and a flat
top post front sight. The rear sight
is adjustable for windage, the
front sight for elevation. Our
semi-automatic hunting rifles are
sighted-in optimally at 100 m on a
machine rest
.

Telescopic sight clamp mount
j
Our HK05 clamp mount readily
accepts all standard telescopic
sights. Should you wish to use an
aluminum rail-type telescopic
sight, loosen the two hexagon
socket screws on the bottom of
the 05 clamp mount, slide on the
telescopic sight and tighten the
two hexagon socket screws firmly
at the rails. If you are using a
steel telescopic sight, please also
use the retaining rings.
Mounting the telescopic sight-
First press the tension lever on
the HK05 clamp mount down-
ward. Place the pairs of clamping
aws into the recesses in the
upper receiver of the rifle and
swivel the tension lever upward.
The telescopic sight is now
securely and firmly mounted on
the rifle. The quick snap on / snap
off HK 05 mount is very easy
to use.
