SAFETY INSTRUCTIONS
Always follow the safety instructions for your own safety and the safety of others.
1. Always handle your firearm as if it were loaded.
2. Never point your firearm at anything you do not intend to shoot.
3. Never take anyone's word that a firearm is unloaded.
4. Always make sure that your firearm is not loaded before laying it down, or handing it to another person.
5. Always store your firearm unloaded with the striking mechanism released.
6. Never abuse your firearm by using it for any purpose other than shooting.
7. Never leave the firearm cocked and ready to fire unattended.
8. Before loading your firearm ensure that the barrel bore, chamber, and action are clean and clear of obstructions. After
shooting, clean a dirtied firearm as soon as possible.
9. Always use only clean, dry, original high quality commercially manufactured ammunition, which is appropriate to the
calibre of your firearm.
10. Never drink alcoholic beverages or take drugs before or during shooting.
11. If possible wear both safety glasses and ear protection when shooting.
12. Always keep the safety on when the firearm is loaded and cocked, until you are ready to fire.
13. Always keep clear of, and keep others clear of the ejection port.
14. Never squeeze the trigger or put your finger in the trigger guard until you are aiming at a target and ready to shoot.
15. Always be absolutely sure of your target, and the area behind it, before you squeeze the trigger. A bullet could travel
through or past your target up to several hundreds of meters.
16. Never shoot at a hard surface such as rock, or a liquid surface such as water.
17. Never fire your firearm near an animal unless it is trained to accept the noise.
26
AUTOMATIC RIFLE MOD. 58 - INSTRUCTION MANUAL
18. Never indulge in “horseplay” while holding your firearm.
19. Failure to fire: always hold the firearm, keeping it pointed towards the target, or a safe open area and wait 30 seconds
when the firearm fails to fire. If a hangfire (slow ignition) has occurred, the round will fire within 30 seconds. If the
round does not fire, remove the magazine, eject the round and examine the primer; if the firing pin indent on the
primer is light, or off centre, or non-existent, have the firearm examined by a competent gunsmith.
20. Always make sure your firearm is not loaded before cleaning, storing or travelling.
21. Always keep and store your firearm and ammunition in separate locked receptacles out of the reach and sight of
children and untrained people.
22. Never alter any parts of your firearm as the safety and proper function of your firearm could be seriously compromised.
23. Always be aware that corrosion, use of damaged ammunition, dropping the firearm on hard surfaces or other “coarse
treatment” could cause damage you may not see. If something like this happens, have the firearm examined and
tested by a competent gunsmith.

AUTOMATIC RIFLE MOD. 58 - INSTRUCTION MANUAL
FIREARM DESCRIPTION AND TERMINOLOGY
Nomenclatures of all Model 58 Automatic Rifle parts are presented in the section Illustration and List of Parts.
Model 58 Automatic Rifle in cal. 7,62 x 39 mm is a weapon of an individual intended for annihilation of enemy
manpower by firing, by means of stock or bayonet, especially in hand-to-hand fighting. The rifle is designed for Mod. 43
cartridge.
The bolt operation is actuated by ignited powder charge combustion resulting in pressure on the piston from gases
generated in the barrel. The portion of gases is tapped off into the gas cylinder, and with the pressure exerted on the
piston head drives the breech block carrier rearwards. At the end of the breech block carrier travel the compressed return
spring forces the bolt and breech carrier to move forward to its initial position.
The automatic rifle is made in the version with wooden stock under denomination Mod. 58 P Automatic Rifle or in the
version with folding stock under denomination Mod. 58 V Automatic Rifle.
The fire can be conducted in single shots or in bursts and that both with the use of sights applying any position of the
shooter utilising rests or without rests and from the hip in the course of march without any halt. The weapon is fed from a
magazine with a 30 cartridge capacity. When the last cartridge from the magazine is fired, the bolt will remain locked
open. The firing is efficient up to 600 metres at ground targets, and as for the targets in the air it is efficient up to 500
meters in single shots and up to 400 meters in bursts. As for group targets, the firing is efficient up to a range of 800
meters.
The Mod. 58 Automatic Rifle is of simple design and is easy to operate and thus ever-ready for immediate use. The
weight and dimensions of this automatic rifle facilitate successful use especially at trenches, communication trenches,
settlements, mountains, woods and the like.
When properly maintained and used, its firing performance and properties remain reliable and safe even under
adverse conditions. No tools are needed when stripping/disassembling this automatic rifle for cleaning and preserving.

OPERATING INSTRUCTIONS
Ammunition
Use only factory-manufactured standard ammunition of an appropriate caliber, which is in compliance with CIP
regulations (International Proof Commission for Firearms), or SAAMI (Sporting Arms and Ammunition Manufacturers'
Institute Inc. of the United States). The use of other cartridges could damage the firearm or cause malfunctions or injury to
the shooter.
Stock Unfolding
Grasp from below the automatic rifle handguard with your left hand. Place your right hand thumb on the bolt cover and
with the right hand index finger press the folding stock pawl stud up to the stop. Inclining the weapon unfold the stock arm
to the right, release the stud and continue the right-hand unfolding till the stock pawl lug audibly snaps in the cut-out of the
stock arm front head.
Stock Folding
Hold the automatic rifle by the left hand at the fore-end from below and place the right hand on the stock arm from the
left side. Rest the right hand finger against receiver cover and using index finger press the stud up to stop. Using the right
hand continue in folding the stock to the right-hand side of the receiver until the folding stock pawl lug audibly snaps in the
cut-out on the front head of the stock arm.
Removal of the Magazine
Grasp the automatic rifle with the right hand at the pistol grip and using the left hand hold the front wall of the
magazine. Place the left hand thumb on the magazine catch and press it forward (Fig. 2). At the same time tilt magazine
forwards in the direction of barrel, and take it out from the magazine well in the receiver.
29
AUTOMATIC RIFLE MOD. 58 - INSTRUCTION MANUAL
Magazine Loading
With the open end uppermost, grasp the magazine in one hand. Place a cartridge on the magazine follower with its
head towards the rear flat edge of the magazine and press it down until the cartridge is caught under magazine retaining
lips (Fig. 3). Place the next cartridge on top of the previous cartridge and slide in the manner as described above.
Rifle Loading
ALWAYS MAKE SURE THE RIFLE IS POINTED IN A SAFE DIRECTION WHEN LOADING!
Grip the rifle with the right hand by its pistol grip and using left hand insert a loaded magazine into magazine well
located at the bottom of the receiver. Firstly engage the front lugs, located near the mouth of the magazine, with the
recess at the front wall of the magazine well in the receiver. Then tilt the magazine rearwards pushing it home into
magazine well until the magazine catch projection audibly engages with the lug located at the rear rim near the mouth of
the magazine. Afterward grasp the rifle from below with your left hand by the fore-end and place the other hand on cocking
handle of the bolt carrier. Pull cocking handle to the rear up to stop and then release it (Fig. 4). The rifle is now ready to
fire. If you do not intend to fire immediately, ensure the firearm safety as described below in the section The Safety and its
Operation.
Semiautomatic Fire
Semiautomatic fire can be initiated after shifting the safety-selector lever to its “1” position, i.e. rearwards. After pressing
the trigger a single cartridge is discharged. The next cartridge is fired after the trigger is released and pressed again.
Automatic Fire
For fully automatic fire (short - 3 to 4 shots, long - 10 to 30 shots), it is necessary to change the safety selector position
to “30” i.e. forwards. If the automatic rifle is loaded, and the magazine holds a sufficient number of cartridges, then firing
can be initiated at any time by pressing the trigger, and interrupted by releasing the trigger. The length of the burst
depends on how long the trigger is depressed, and can be from 2 cartridges up to the full capacity of the magazine.
30
AUTOMATIC RIFLE MOD. 58 - INSTRUCTION MANUAL
Reloading During Shooting
When the last cartridge has been fired, the bolt stays in its rear (locked open position). Remove the emptied magazine
and replace it with a loaded one. Partially retract the bolt, and release it to snap forward. The rifle is loaded again, and
ready to fire.
The Safety-Selector and its Operation
Rotate the safety-selector lever perpendicularly downwards. This prevents discharge of the cartridge as the firing pin is
blocked and cannot be released. This method of putting the safety-selector lever to Safety-On position does not preclude
any standard operation of other parts of the bolt except the striker, so it is possible to load or unload the cartridge from the
cartridge chamber.
Unloading the Rifle
ALWAYS MAKE SURE THE RIFLE IS POINTED IN A SAFE DIRECTION!
In the case that the last cartridge from the magazine has not been fired proceed as follows:
- Shift the safety-selector lever to “Safety-On” position
- Remove the magazine
- Manually retract the bolt up to the stop thus unloading the cartridge from the cartridge chamber
- Shift the safety-selector to position marked „30“, i.e. forwards
- Cock the bolt using bolt carrier handle up to the stop
- While keeping the trigger pressed release the bolt to snap forward, this operation disengages firing pin and its
spring
- Put the automatic rifle again to “Safety-On” mode
31
AUTOMATIC RIFLE MOD. 58 - INSTRUCTION MANUAL
In the case that the last cartridge from the magazine has been fired and the bolt is locked open in its rear position then
proceed as follows:
- Remove the magazine
- Shift the safety-selector to position marked „30“
- Cock the bolt using bolt carrier handle up to the stop
- While keeping the trigger pressed release the bolt to snap forward, this operation disengages firing pin and its
spring
- Put the automatic rifle again to “Safety-On” mode
Sight Adjustment
The tangent rear sight can be adjusted after depressing the rear sight locking piece and shifting the slide to desired
range determined by the lines 1 up to 8, which denominate range of fire in hundreds of meters (Fig. 5). Besides this the
left sight of the rear sight leaf is marked by letter „U“ (universal), for shooting at moving targets and night combat at ranges
up to 300 meters.
The front sight can be adjusted for elevation and windage by the degree of screwing it into the front sight peg. The front
sight rack features in its front face semicircular recess, which exposes middle portion of the front sight pin. The front sight pin
and the rack wall recess are provided with two sighting-in lines. When these two lines are just opposite then it indicates the
correct windage position of the front sight. The correct front sight position regarding elevation is secured by the drop of nitropaint applied to the face of the front sight and its rack. Screwing up (screwing down) the front sight, change in the height by 1
thread (0,5 mm) or shifting the front sight pin to the side by 0,5 mm shifts the mean point of impact by 14 cm at 100 meters.
Bayonet Installation and Removal
Grip the bayonet with your left hand by the handle and put it from below onto rails located on the rack and slide it to the
rear until the bayonet catch engages into slot at the rack. Before bayonet removal press the catch sited at the left side of
the bayonet and subsequently slide the bayonet off the rifle.

33
AUTOMATIC RIFLE MOD. 58 - INSTRUCTION MANUAL
CAUTION:
No further disassembly is needed for routine maintenance and preserving. Never attempt to disassemble your
automatic rifle further. If you assume that your automatic rifle requires adjustment or repair, then entrust this task to a
competent gunsmith.
Assembling the Rifle
1. Using your left-hand grasp the rifle from below by the fore-end. Grasp the piston with the slipped-over spring and insert
its cylindrical part downwards up to stop into opening of the rear sight base. Tilt the piston head to the cylindrical seat
of the gas cylinder and release the piston. Under the spring pressure the piston will be shifted to its front position.
2. Make the tips of handguard front joiner snap in the grooves on the gas adapter and tilt the handguard down. Insert
handguard pin completely to the left thus securing handguard against any inadvertent release.
3. Place the breech lock into seating at the breech block. Put the breech block in recess sited at breech block carrier
near the bridge, whereupon shift it forwards to engage the grooves in the carrier. Shift the striker-hammer partially in
the breech block carrier so that the witness marks on the striker-hammer and the rear wall of the breech block carrier
are oriented opposite to each other (Fig. 11). Then turn the striker-hammer by the full length of the witness mark to
the right and insert it into striker-hammer carrier up to stop.
4. Grasp the assembled bolt by the right hand with thumb placed against the rear face of breech block carrier and the
middle finger against the front face. Using left hand hold the rifle from below by the receiver with muzzle slightly
inclined to the ground. Insert the bolt from above in the rear part of the receiver. Slid the inserted bolt as far as the
extreme front position, whereby the striker-hammer remains retained by the left-hand catch of striker (Fig. 12).
34
AUTOMATIC RIFLE MOD. 58 - INSTRUCTION MANUAL
5. First of all, insert the striker-hammer spring (operating spring) partially in the cavity of striker and then the return spring
in the opening of breech block carrier (Fig. 13). Shift the Safety-Selector lever to position „1“ or „30“ and squeeze the
trigger. This releases the striker-hammer from the left-hand catch and return mechanism can be moved forwards
without any resistance. Pull the front part of the cover under to engage the grooves in the carrier and by pushing
forwards and downwards slid the projection of base in the recess in the rear part of the receiver (Fig. 14).
Subsequently lock the return mechanism by inserting receiver cover pin until an audible click is heard. If the strikerhammer is not released by squeezing the trigger then it means that the breech block carrier is not in the extreme front
position and the striker is held by the right hand catch.
Assembled Rifle Inspection
When inspecting assembled rifle it is necessary to check
- Function of the bolt
- Function of the trigger unit
- Correctness of the rear sight and front sight
- Fixing of the bayonet
- Function of the shoulder rest
Function of the bolt: On cocking the movement of parts and components must be smooth without any hitch or sticking
with a considerable resistance of the return spring. The bolt when released must move vigorously in the forward direction,
while the breech block carrier must run as far as its extreme front position and lean against the face of casing. When the
empty magazine is inserted into the rifle then the bolt catch must intercept the bolt in its forward movement in the locked
open position. Correctness of feeding, extracting and ejecting is verified by manual cycling of the bolt while using a
magazine loaded with dummy cartridges. In this way also the function of the magazine and magazine catch is checked.
The magazine catch lug must audibly snap in behind the projection at the rear edge near the magazine mouth. Without
depressing the magazine catch the magazine shall not be free to be removed. After checking the bolt function the strikerhammer spring must not remain depressed (under tension).
35
AUTOMATIC RIFLE MOD. 58 - INSTRUCTION MANUAL
Function of the trigger unit: Must be carried out with dummy cartridges only! Dry fire is not allowed! Shift the safetyselector lever to position „1“ or „30“ and repeatedly by hand insert dummy cartridge into the cartridge chamber. The
striker-hammer must be released when the trigger is squeezed and striker-hammer impact on the firing pin must be
clearly audible. If the safety-selector lever is set to the “Safety-On” position, i.e. downwards, the striker-hammer must not
be released by squeezing the trigger. The safety-selector lever must manifest positive positioning accompanied by an
audible click when desired position is reached. A certain force must be exerted for changing of safety-selector lever
position.
Correctness of the rear sight and front sight: It is necessary to check whether the rear sight leaf has no lateral play
and if it is not bent. If the rear sight locking piece is depressed then the rear sight slide shall move easily along the leaf and
in all its positions must be forced down to the rear sight ramp by the force the rear sight spring. The locking piece lug must
properly engage into all notches of the rear sight leaf. As to the front sight it is necessary to check whether the front sight
is not damaged and whether zeroing lines are aligned and if the elevation setting is not displaced (this could be found out
from the integrity red nitro-lacquer drop inside the front sight cover).
Fixing of the bayonet: The bayonet when fixed to the rifle must not wobble too much or move in the longitudinal
direction.
Function of the shoulder rest: For the rifles in retractable shoulder rest version check whether shoulder rest is locked in
the folded position. When the shoulder rest is unfolded it must be steady and must not wobble too much. After depressing
the folding shoulder rest stud the shoulder rest unfolding and folding shall be light and smooth.

38
AUTOMATIC RIFLE MOD. 58 - INSTRUCTION MANUAL
Cleaning the Rifle
Clean the rifle
- Each time you use it
- If you get your automatic rifle wet
- As soon as possible after shooting
- At least once a year in a temperate climate
- As often as once a month in a tropical climate, or other demanding environments
Cleaning and Materials Used
- clean fine cloth/swab suitable for cleaning and lubricating of parts and components
- roughly comb hemp oakum without chaff (only for barrel bore cleaning)
- cleaning gun oil for preparing of water emulsion by mixing on part of cleaning gun oil with three parts of water for
solving dirt and fouling on the parts exposed to propellant generated gases (barrel bore, bolt, piston)
- water solution of SOD cleaning agent is used as a substitute for cleaning gun oil outside cold weather season. The
solution is prepared by solving bag contents (16 g) at one litre of water.
- paraffin oil for lightening is used for solving and washing of hardened old lubricants (P vaseline), fouling and
corrosion. After using the paraffin oil the parts must be carefully wiped dry with an oakum and then by dry clean
cloth followed by preserving.
- Hairbrush (included in accessories)
39
AUTOMATIC RIFLE MOD. 58 - INSTRUCTION MANUAL
Cleaning the Barrel Bore and the Cartridge Chamber
The barrel bore shall be cleaned from the side of the muzzle. For doing this it is necessary to screw both parts of
cleaning rod and oakum holder together (Fig. 15). Slid the muzzle protection over cleaning rod. Insert the cleaning rod end
with annular groove into longitudinal opening of at the unscrewed oil-can plug and secure it with front sight wrench, which
is put through transversal opening in the oil-can plug. Wind a layer of oakum round the oakum holder so that it could pass
through the bore with a slight resistance in order that it fills the grooves well. Then dip oakum in cleaning gun oil emulsion
or to water solution of SOD cleaning agent and insert oakum holder with wrap around oakum in the barrel bore and
thoroughly scrub in the direction from the muzzle. Slid muzzle cap over muzzle thread protection and rotate in such a way
that the muzzle thread protection lock is engaged in cut-out of the muzzle cap.
Grasp the cleaning rod by the front sight wrench and plug and push-pull the cleaning rod with its attachment
continuously without any undue force seven or ten times through the whole length of the bore. After this remove the
muzzle cap, pull the cleaning rod out and replace the oakum; dip it again in the cleaning agent and again draw several
times the cleaning rod through the bore. Then remove emulsion off the cleaning rod and the oakum holder, and push-pull
a dry clean cloth through. Repeat cleaning with the cloth a few times if the cloth shows some spots from corrosion, powder
residues or fouling. If the cleaning cloth do not come out clean even after repeated wiping then it is necessary to repeat
cleaning using oakum and SOD cleaning agent and then again wipe the barrel bore dry with clean cloth. When the last
cloth comes out without any traces showing residues of fouling or corrosion then clean the cartridge chamber.
For cartridge chamber and piston cylinder cleaning is the oakum holder screwed into the transverse opening of the oilcan plug from the threadless side of the opening. The cartridge chamber is then cleaned in the same way as the barrel
bore, at which the oil-can when in vertical position serves as oakum holder handle.
40
AUTOMATIC RIFLE MOD. 58 - INSTRUCTION MANUAL
Cleaning of Other Rifle Parts
Piston cylinder scrub with oakum wetted with SOD cleaning agent and then wipe dry. Perform cleaning procedure till all
firing residues and/or fouling are removed. Piston cylinder wiped dry is preserved with a thin film of P vaseline.
When cleaning the piston, it is necessary to pay attention to removing fouling or other deposits from the circumferential
groove on its head. After washing over in cleaning agent the piston shall be wiped with oakum. After removing fouling or
other deposits and dirt the piston shall be wiped dry and preserved with a thin film of P vaseline.
Receiver, bolt and the non-disassembled trigger unit, rear sight and return mechanism shall be cleaned using wooden
sticks with wound-up cloth wetted with cleaning gun oil. Openings, grooves, cut-outs and recesses are cleaned using
pointed wood sticks. After cleaning the parts and components shall be wiped dry using a clean cloth and then preserved
with P vaseline. It shall be also checked whether after cleaning of the non-disassembled trigger unit are the positions of
trigger unit parts correct, especially trigger unit spring legs.
The components which are badly fouled with powder combustion residues may be immersed in the cleaning solution
for a time of 30 min. at most, as the longer time is not purposeful. Remnants of cleaning solution shall be carefully
removed. Never leave any gun cleaning solution or its emulsion at the barrel bore.
The wooden parts of the rifle, i.e. the stock, pistol grip and fore-end, shall be wiped with a lightly oil soaked cloth and
then wipe dry with clean dry cloth. From time to time apply light impregnation using wood (linseed) oil.
Lacquered parts of the rifle, such as the external surface of the barrel, receiver, trigger guard, receiver cover and
buttplate are not preserved but rubbed with grease cloth and then using clean dry cloth wiped.
In the winter season use only paraffin oil when temperatures go below -2° C (28°F).
41
AUTOMATIC RIFLE MOD. 58 - INSTRUCTION MANUAL
Preserving
Preserving Material Used
- preserving vaseline designated as P for the rifle metal parts protection. This vaseline is applied for the whole year
provided that the temperature is not below -10°C (14°F). Vaseline P must not contain any moisture. If there is a
suspicion of moisture in the lubricant the vaseline and oil must be made free from moisture by warming up to
temperature in the scope of 105 to 115°C (221 to 239°F). The vaseline when not pre-heated may be used only for
the short term preserving.
- gun oil to lubricate the matching (friction) surfaces that are in use
- wood or linseed oil to impregnate wooden parts of the firearm
Before beginning of the barrel bore and cartridge chamber preservation pull a cloth soaked with P vaseline through cutout in the oakum holder. The cloth must be of such a size so as to pass through the bore snugly. Push-pull the cleaning
rod with attachment two or three times through the entire length of the bore so that the preserving agent is well adhered to
the grooves and lands of the bore and cartridge chamber and forms a thin continuous layer. Excessively greased parts
collect dirt very rapidly and for this reason it is necessary to apply only a fine layer of preserving agent using a grease
soaked cloth. When lubricating recesses, grooves and slots it is necessary to roll the cloth round a wooden stick.
Preserving the barrel bore with the gun oil protects against corrosion only for a few days at most. If the bore wiped out dry
is left without preserving agent for more than an hour, it collects damp due to the effect of ambient air and the preserving
agent must not be applied to until the bore is re-wiped out dry with a dry clean cloth. When preserving the rifle in the
course of regular use during winter season in frosty weather with temperatures below -10° C (14°F) apply a mixture of gun
oil and P vaseline in 3:1 ratio. If the temperature drops below -30° C (-22°F), apply for a short time preserving a pure gun
oil. The oil can be applied only to the -40° C (-40°F), temperature but is not any guarantee for the long-term resistance
against corrosion.
42
AUTOMATIC RIFLE MOD. 58 - INSTRUCTION MANUAL
Checking the Zeroing of Rifle and Zeroing-In
The zeroing is checked only in the situation when in the course of fire an unusual or abnormal deviation of impacts,
spread/dispersion occurs or in the cases when replacement of parts and/or components or repair has been carried out
which as a consequence could impair rifle zeroing. For checking of zeroing and zeroing-in, only the Model 43 cartridges in
cal. 7,62 mm are allowed to be used. All cartridges must be of the same production series. The automatic rifle zeroing is
checked for a range of 100 m, at which the rear sight is set to the range „3“. Firing is carried out either with the fixed
bayonet or without bayonet at the white target at 1 metre (3,28 ft) in height and 0,5 metre (1,64 ft) in width. The point of
aim is in the middle of the bottom edge (black rectangle) of the shooting-in target, which is to be approximately on a level
of rifleman’s eye. The normal position of the mean point of impact shall be marked on the vertical line passing through the
aiming point. This mean point of impact, when the rear sight is set to „3“ should be at the height 28 cm (11in.) above the
aiming point and at the same time it is the checking point when determining the accuracy of the automatic rifle zeroing.
Round the checking point, the checking circle of 10 cm (3,9in.) in diameter is circumscribed. Firing is carried out in prone
position (lying) with a rest. When firing the hand holding the rifle must be placed against the rest. Then 4 cartridges
individually, accurately and steadily aimed are shot at the middle of the bottom edge of the black rectangle while the
rifleman in the course of shooting is not changing neither the position of his body nor of the hand.
The rifle is considered to be zeroed-in if all the four hits - in extreme case 3 of the hits (if one of the hits shows a great
deviation from others; so called flyer) - may be covered with the circle of 18 cm (7,08 in.) diameter and if, simultaneously,
the mean point of impact is not deviated more than 5 cm (1,96 in.) to any side from the checking point.
