Bolt
The ANSCH†TZ bolt
The ANSCH†TZ bolt is designed to be ex-
tra  strong and reliable and is manufactured
to the closest tolerances. Bolt and cam are
lapped to assure very smooth operation. It
has a double locking device. When the
wing safety is in the down position both the
firing pin and the bolt handle are locked.
When it is in the horizontal position the rifle
may be fired and/or the bolt handle raised
to operate the bolt. Due to a short firing pin
travel and a low-weight firing pin the lock
time is very fast.
To disassemble the bolt
Make sure the rifle is pointed in a safe
direction, remove the magazine and make
sure that the cartridge chamber is
completely clear. Then raise the safety to
the horizontal position and pull the bolt
back towards you as far as possible.
¥Hold the bolt as shown and turn the bolt
handle clockwise and the wing safety
counter-clockwise as far as they will go. ¥Depress bolt stop on left side of receiver
and pull bolt out to the rear. This removes
the bolt from the receiver. 
						

							35
Caution:
¥For rifles in cal. .222 Rem. depress the
catch at the base of the bolt handle as
shown.
¥Hold bolt with safety up and remove
safety with signal pin and spring as
shown.¥Now remove the firing pin assembly. ¥Next remove sleeve 
						

							36
¥Replace the sleeve and make sure that
the slot in the sleeve lines up with the firing
pin lug. ¥Replace the firing pin assembly and make
sure that the lug lines up with the longer
slot in the bolt body and the bottom of
the recess at the bolt handle as shown.
¥Replace bolt handle as shown. ¥Then remove the bolt handle assembly.
To re-assemble the bolt
Follow the disassembly procedure in
reverse order as follows. 
						

							37
¥Replace the safety with the signal pin and
spring and make sure that the safety wing
lines up with the firing pin lug and that the
signal pin is properly seated.
¥Turn the bolt handle counter-clockwise
and the wing safety clockwise as fas as
they will go. The bolt is now assembled
and cocked.¥With the bolt handle slightly above hori-
zontal replace the bolt in the receiver and
close the bolt.
¥The bolt is now cocked and in firing
position. To unclock the bolt lift the bolt
handle as high as it will go, depresse the
trigger as far as it will go and place the
bolt handle down. The bolt is now closed
and uncocked. The signal pin at the rear
of the bolt should not project showing that
the bolt is now uncocked.
Trigger
Warning:
Your ANSCH†TZ trigger offers you a
variety of individual adjustment possibilities.
Please note that your rifle always must be
unloaded when any adjustment is carried
out.
Please see the adjusting range for the
referring model from the trigger chart. It
might be necessary to remove the stock from
the barreled action for adjustments at the
trigger.
Trigger adjustments must only be carried
out by an authorized gunsmith. Modi-
fications at factory-set triggers might cause
severe injuries or death.
Please also see the chapter ãGeneral
handling of rifles and pistolsÒ.

Two and single stage triggers
1. Trigger weight
Adjust the trigger weight with set screw
No. 2:
¥if you turn it to the right (clockwise):
trigger weight is increased (+)
¥if you turn it to the left (counter-clockwise):
trigger weight is decreased (-)
Trigger weight and first stage weight
depend on each other with regard to the
mechanic mechanism. If one of them ischanged there will always be a corres-
ponding change of the other as well.
2. Sear engagement
The sear engagement is the distance bet-
ween the second stage and the release of
the trigger.
Important note:
To protect your precise trigger and to
guarantee perfect operation you should
always close the action carefully. If the sear
engagement of single stage triggers is too
small and the trigger weight is too low or if
the first stage of two-stage triggers is too
short, the trigger might release inadvertently
by a sudden impact or too powerful closing
of the action if the gun is loaded and not in
the ÓsafeÒ position.
Adjustment of the sear engagement for
assembled two-stage triggers with set
screw No. 1:
¥if you turn it to the left (counter-clockwise):
sear engagement is shortened
¥if you turn it to the right (clockwise):
sear engagement is extended
Adjustment of an optimum sear engagement:
Make sure your rifle is not loaded. Cock
your rifle and release the trigger. Check if
the trigger releases as desired.
The sear engagement is too long:
There is a small distance between the
second stage and the release of the trigger.
¥Turn set screw No. 1 counter-clockwise
after cocking and releasing (approxi-
510 8

mately 1/8 turn each).
¥Repeat this process until you do not feel
the second stage anymore. Then turn
1/4 turn back to the right. Thus the
optimum sear engagement is adjusted.
The sear engagement is too short:
There is no second stage. The trigger
releases un-defined without second stage.
¥Turn set screw No. 1 clockwise  for at least
1/4 turn after cocking. Then release the
trigger and check if there is a second
stage. If not, repeat this procedure until
you feel a second stage.
¥As soon as you feel a second stage
proceed according to the points of the
paragraph ãThe sear engagement is too
longÒ to obtain an optimum sear engage-
ment.
Adjustment of the optimum sear
engagement for assembled single stage
triggers with set screw No. 1:
¥Cock the rifle.
¥Turn set screw No. 1 (first stage) as long
to the right until the trigger releases.
¥Turn set screw No. 1 from this position
approx. 
1/4 turn to the left.
Warning:
Single stage triggers are very sensitive and
must be operated with special care.
The sear engagement of 
5/100 mm is ob-
tained after the action is closed. In
combination with a minimum trigger weight
there might be a malfunction and an
increased risk (independent shot
release).
3. Malfunctions of the trigger due to
wrong adjustment procedure
If the trigger is not adjusted correctly mal-
functions may occur, tampering with the
trigger adjustments will not result in any
success. Therefore proceed as follows:
After every change the function of the
trigger must be checked. When the
malfunction is removed check the desired
trigger values and adjust them again if
necessary.
The trigger catches the cocking piston or
firing pin, but the trigger does not release:
¥Make sure that the safety of the trigger is
released.
The trigger does not catch the cocking
piston or firing pin:
¥The first stage trigger is adjusted too
tightly.
¥Turn set screw No. 1 approx. 1-2 turns to
the left. Procede according to par. 2.
4. Safety
There is a safety lever at the right side of
the trigger. Please see chapter ãCocking,
loading and safety operationÒ.
5. Maintenance
Please see chapter ãCleaning, mainte-
nance, care, oilsÒ.

the trigger immediately. Never walk about
with the trigger cocked.  Before you load
the rifle check that the trigger really does
operate properly.
You should be able to fire a round in these
following three ways:
¥Pull the front trigger until the rifle fires.
¥Push the rear trigger forwards towards the
muzzle until the rifle fires.
¥Normal way as described before under
the description of the operation of the
double set trigger.
Unclocking the double-set trigger when
the rifle is loaded:
Extreme care must be exercised on
uncocking the double-set trigger.
¥Set the safety by pressing down the wing
of the wing safety being located at the
end of the bolt.
¥Press it down until it comes to a stop. The
graduated line must be straight in line with
ãSÒ (safe). Hold the rifle in such a position
that no damage or injury is caused if a
round is fired inadvertently.
¥Unclock the double-set trigger by pulling
the front trigger.
There is a further, silent method of uncocking
the double-set trigger. Here, too, the safety
lever must be set to prevent the rifle from
firing.
¥Pull the rear (second) trigger towards you
with your middle finger to the stop and keep
the trigger in this position.
¥Now pull the front (first) trigger towardsDouble set hunting trigger
The models of the series 1700 ST are
equipped with  a double set hunting trigger.
The purpose of this trigger is to fire the shot
with a minimum of trigger pressure (hair
trigger). The double set trigger is operated
as follows:
¥Pull the rear trigger towards you until it
engages with an audible click. The trigger
is now cocked. CAUTION: If the release
pressure of the double-set trigger is
adjusted too low, the shot could go off
by vibration. The release pressure is
adjusted with the set screw (see picture).
Turn counter-clockwise for higher pressure,
clockwise for lower pressure. The double
set trigger must only be adjusted by an
authorized gunsmith.
¥Once the trigger has been cocked the
round can be fired by merely touching
the front trigger (first trigger). Do not touch
this trigger unless you really do wish to
fire.
Attention:
Do not shake the rifle or expose it to
vibrations once the trigger has been
cocked. Stay at the place you wish to fire
from because otherwise the round could be
fired inadvertently. If you do not fire, uncock

you with your index finger to the stop and
hold it there until you have slowly released
the rear trigger and it has returned to its
normal position.
¥Afterwards slowly release the front trigger
in the same manner.
Note:
In both cases the bolt remains cocked. The
trigger can be cocked again if desired.
Attention:
Exercise the greatest care when performing
the foregoing actions. Practise several times
with an unloaded rifle until you have
thoroughly mastered the procedure and
always ensure that the rifle is pointed in a
safe direction at any time.
After firing, the empty case is ejected by
opening the bolt. A new cartridge is loaded
into the chamber by closing the bolt. Your
rifle is now ready to fire the next round.

1. Trigger weight
Adjust the trigger weight with set screw
No. 10 (silver screw):
¥if you turn it to the right (clockwise):
trigger weight is increased (+)
¥if you turn it to the left (counter-clockwise):
trigger weight is decreased (-)
Trigger weight and first stage weight
depend on each other with regard to the
mechanic mechanism. If one of them is
changed there will always be a corres-
ponding change of the other as well.
To move trigger cam No. 11:
¥lowest position of the trigger cam:
lowest trigger weight
¥highest position of the trigger cam:
highest trigger weight
If the trigger weight is to be more than 200 g,
the trigger cam No. 11 must be adjusted to
iuo

the highest position (turn it by 180° and fix
it then). To do this you need a 2 mm hex
key and perhaps tweezers.
¥if you turn it to the left (counter-clockwise):
You release the screw
¥if you turn it to the right (clockwise):
You tighten the screw
Attention:
Please ensure the trigger cam is positioned
correctly. Be very careful tightening the
small cam screw as it is easily broken!
Please check the sear engagement accor-
ding to paragraph No. 3 when you have
finished this process. It might have to be
adjusted as well. The precise adjustments
of the trigger weight and first stage weight
are carried out with the set screws No. 10
(trigger weight) and No.9 (first stage weight).
2. First stage weight (only for two-stage
triggers)
Adjust first stage weight with set screw
No. 9 (black screw):¥if you turn it to the right (clockwise):
first stage weight is increased (+)
¥if you turn it to the left (counter-clockwise):
first stage weight is decreased (-)
Trigger weight and first stage weight
depend on each other with regard to the
mechanic mechanism. If one of them is
changed there will always be a corres-
ponding change of the other as well.
Attention:
Do not reduce either trigger weight screw
to zero or lower as the trigger pull may
become erratic.
3. Sear engagement
The sear engagement is the distance bet-
ween the second stage and the release of
the trigger.
Important note:
To protect your precise trigger and to
guarantee perfect operation you should
always close the action carefully. If the sear
engagement of single stage triggers is too
small and the trigger weight is too low or if
the first stage of two-stage triggers is too
short, the trigger might release inadvertently
by a sudden impact or too powerful closing
of the action if the rifle is loaded and not in
the ÓsafeÒ position.
Adjustment of the sear engagement for two-
stage triggers with set screw No. 5:
¥if you turn it to the right (clockwise):
sear engagement is shortened
¥if you turn it to the left (counter-clockwise):
sear engagement is extended

Adjustment of an optimum sear engagement:
Make sure your rifle is not loaded. Cock
your rifle and release the trigger. Check if
the trigger releases as desired.
The sear engagement is too long:
There is a small distance between the
second stage and the release of the trigger.
¥Turn set screw No. 5 clockwise after
cocking and releasing (approximately
1/8 turn each).
¥Repeat this process until you do not feel
the second stage anymore. Then turn
1/5 turn back to the left (counterclock-
wise). Thus the optimum sear engagement
is adjusted.
The sear engagement is too short:
There is no second stage. The trigger
releases un-defined without second stage.
¥Turn set screw No. 5 counter-clockwise
for at least 
1/4 turn after cocking. Then
release the trigger and check if there is a
second stage. If not, repeat this proce-
dure until you feel a second stage.
¥As soon as you feel a second stage
proceed according to the points of the
paragraph ãThe sear engagement is too
longÒ to obtain an optimum sear engage-
ment.
For the adjustment of the sear engagement
for single stage triggers with set screw
No. 5 see point 7:
4. First stage (only for two-stage
triggers):
The single stage is the distance betweenthe trigger blade from zero position to the
second stage.
Adjustment of first stage with set screw No. 4:
¥if you turn it to the right (clockwise):
first stage is shortened
¥if you turn it to the left (counter-clockwise):
first stage is extended
Caution:
Set screw No. 4 (first stage) can be turned
past the second stage function. In this case
the trigger does not work anymore. Dan-
ger! Do not under no circumstances remove
the first stage completely in order to change
the two-stage trigger into a single stage
trigger.
5. Trigger stop:
The trigger stop is the distance from the se-
cond stage to the stop of the trigger blade.
Adjustment of the trigger stop with set screw
No. 8:
¥if you turn it to the right (clockwise):
overtravel is shortened
¥if you turn it to the left (counter-clockwise):
overtravel is extended
Attention:
The trigger stop set screw No. 8 can be
turned over the second stage or first stage
function. Malfunction (the trigger does not
release)!
