Disassembly / Reassembly the Mauser 98k
* ** *** **** ***** **** *** ** *
The first steps to take are safety oriented…
Lift the safety lever to the upright, or vertical position.
Open the bolt and remove it from the rifle by opening the bolt
release lever located on the left rear side of the receiver.
Check to see that the magazine is empty, the chamber is empty
and that you can see that the barrel is unobstructed inside.

the rear and to reassemble, you work from the rear toward the front.
Remove the front sight hood. It is a spring-steel sight-hood that

forward with a piece of wood and it will move forward until it

Next, remove the wide front barrel band. Notice that it is connected
the narrow rear barrel band by a steel bar that is actually a long
spring located between the barrel bands on the right side. The long
spring has a raised surface just aft of the front barrel band. Its
purpose is to enable the unlocking of the barrel bands.

surface of the long spring and encircle the stock just behind the
band. Exert enough pressure until you see that the locking pin is

Now tap the front barrel band forward with a piece of wood. Do not
use a metal tool. It will come forward easily. Tap it all the way
Relax the vice grips.
Next, grasp the long spring and lift it out.
Next, remove the rear barrel band. It has a sling slot on the left

only one direction so remember which way it fits by marking the
‘lead’ end of it with a red marker. Tap the bayonet lug straight
and it will come right off.
Next, turn the rifle over. You can see the trigger guard and
Remove the floorplate. Do so by using a small round piece of wood
(like a wooden pencil; DO NOT use a screwdriver!) and depress the
plunger in the hole at the rear of the floorplate. It will only move

aware of which end of the zig-zag follower spring holds the
floorplate and which end holds the follower. They look alike but
are not. They only go on one way. Otherwise you risk feeding
Next, remove the trigger guard. It is held in place by two large
and two locking screws. Remove the locking screws and remember
where they came from. They are NOT interchangeable. The front lock
screw goes only in the front locking hole and the rear lock screw
goes in the rear-locking hole. Remove the front and rear screws from
the trigger guard.
Grasp the trigger guard and lift it out of the stock. It will come
out. Lift the stock away from the action and barrel. It will lift
The barrel assembly will them be free of the main stock assembly
and will be laying right in front of you!
Next, remove the upper handguard. Do so by first removing the screw
located in front of the rear sight. Grasp the rear underside of the
upper handguard and push it straight away from the barrel. It will
resist you because it has a spring-clamp that you can see that holds
fast to the barrel. Overcome the spring-clamp by pushing the rear of
the upper hand guard loose as mentioned above and lift it free of
barrel. It is easy to damage the front of the upper handguard while
free of the barrel because the front of it is thinner than the rear
The recoil lug remains in the stock. It is normally not removed. If
choose to remove it, you must also replace it during reassembly. On
the right side of the stock you will see a round plate with two
designed for a special spanner wrench. The spanner wrench is
needed to remove (and replace) the round plate because it is tightly
threaded onto the recoil lug. The special spanner wrench is
from us. With the wrench, fit its two prongs into the corresponding
holes and turn the plate counter-clockwise until it backs all the
out. Once out, drive the recoil lug straight out of the stock with a
piece of wood.
Now everything is exposed for cleaning or for ‘dropping-in’ a
stock (that we can supply). Notice that there is one cylindrical
associated with the rear guard screw that generally, but not always,
comes out of the stock with the trigger guard screws. This spacer is
very important. It controls the relationship of the trigger guard to
receiver. You may remove it from the stock if you wish but it is
normally not necessary. Do not lose it! It is vital. The equivalent
spacer is actually ‘built-in’ to the front of the trigger guard;
you can’t lose it.
Next…if you wish, you may take out the trigger assembly. Do so by
driving out the trigger hinge pin around which the trigger
Naturally it doesn’t ‘rotate’ very much. About 10 degrees. The hinge
pin comes out easily but still must be driven out with a small
Once out, the trigger frame and assembly will literally fall out of
receiver; it is that well designed. It has a small coil spring that
small cavity in the trigger frame. The spring is small and easy to
lose. It is also expensive to replace so be careful. The spring is
trigger return spring and without it the rifle will fail.
You can replace the combat trigger with a special hunting /
competition trigger assembly that we can supply. The new trigger
assembly is fully adjustable while combat triggers are not. The new
trigger assembly will ‘drop-in’ in place of the old trigger
Next…if you wish, you may take off the bolt release assembly. It is
located on the left rear of the receiver. It is held in place by a
screw and it fits through two raised lugs built in to the left rear
receiver. You can’t see them until you remove the bolt release
assembly. Just remove the screw in the normal fashion and lift off
assembly but don’t lose it. It is expensive to replace.
Congratulations…you have now detail-stripped the Mauser Model 48.

Leave the bolt out of the rifle at this time.
Attach the bolt release assembly onto the receiver locking it in
with the pointed screw. Make sure it is spring powered and swings
and returns freely; with no drag.
Restore the original trigger assembly onto the receiver making sure
that the spring rests in its cavity and the hinge pin is put
place. Test the movement of the trigger and make sure that it does
not bind in either direction. The trigger-return spring is built-in

floorplate onto the other end of the follower spring. Then reinstall
entire follower assembly into the magazine well.
Notice that the floorplate has two hook-like surfaces that engage
magazine well. Hook the front one first and then depress and slide
forward the rear part of the floorplate. You will be overcoming the
spring-loaded plunger that you depressed to remove the floorplate.
Make sure that the plunger ‘clicks’ audibly into position.
Reinstall the bayonet lug. Do so by sliding it onto the front of the
stock and reinstall its retaining pin. The bayonet lug does not

Reinstall the upper handguard. Snap the clamp over the rear of the
barrel making sure that it ‘goes home’ securely.
Reinstall the rear barrel band. Make sure that the sling-slot of the
barrel band is on the left side of the rifle. Tap the rear barrel
back as far as it will go making sure that it butts up against the

Insert the rear part of the long locking spring under the rear
band within its slot in the stock. Reinstall the front barrel band

order to depress the raised surface of the long locking spring. The
spring must be depressed low enough to be sure the front barrel

Reinstall the front sight hood. It must fit into the grooves on
side of the front sight base. It is a strong spring-hood. Force the
rounded edges into the grooves and then tap it all the way on with a
piece of wood. There is a special tool that will grasp the hood and
allow you to easily ‘spread’ the hood so that you can easily slip
hood onto the front sight base.
Install the bolt assembly into the receiver. Make sure the safety is
the upright, vertical position.
Make sure your rifle is coated with a light coat of high quality gun
Congratulations…you have now properly reassembled your rifle
