Work order — Vz. 58

Taking the firearm apart for a job such as refinishing, and putting it back together to specification. Generated from the Pew-Takedown entry last updated 2026-10-29. Confidence: medium.

Shop difficulty: Tier 2 of 3

84 numbered parts in the manual's figures, with an unusual striker-fired, flat-spring fire-control group retained by e-clips. CZ reserves complete disassembly for a gunsmith workshop, the fire-control group is hard to remove without knowing the trick, and the return mechanism puts two springs in together. 84 parts (Numbered part callouts in the manual's figures 2–23 (rifle and magazine; accessories, sling and cleaning kit excluded); e-clips counted as items). Pew-Takedown's rating, not the manufacturer's.

Bench time: strip ~45 min, rebuild ~70 min (estimate). Actual: strip ______ rebuild ______

Special tools:

• vz.58 needle (issued tool) — Pins and catches
• front sight spanner — Front sight
• e-clip pliers — Trigger and sear pin e-clips

Watch for:

• CZ says complete disassembly is gunsmith-workshop work, with no owner procedure for the fire-control group, sights or handguard pins. (both; CZ-USA (translation of the Czechoslovak military manual; re-hosted on archive.org))
• Getting the fire-control group out without knowing the method gouges the receiver and leads to a lot of fruitless banging. (disassembly; The Firearm Blog)
• The return mechanism goes in with the return spring and striker spring started into the carrier and striker together, then the cover is pushed down and locked. (reassembly; CZ-USA (translation of the Czechoslovak military manual; re-hosted on archive.org))
• A bolt detail strip (firing pin, extractor, extractor spring and stay) is slow, and the firing pin must be aligned with the extractor. (both; Canadian Gun Nutz)

1. Clear and make safe

1. Point the muzzle in a safe direction and keep your finger off the trigger.
2. Rock the magazine forward and out of the magazine well.
3. Pull the charging handle fully rearward. The bolt holds open on an empty magazine on this design.
4. Inspect the chamber and magazine well with a light, then physically confirm the chamber is empty.
5. Place the safety on and remove all live ammunition from the work area.

2. Disassemble

Field Strip

1. Complete the Clear and Make Safe procedure.
2. Depress the receiver cover catch at the rear of the receiver and lift the cover off.
   Warning: The recoil spring assembly is compressed behind it.
3. Withdraw the recoil spring assembly.
4. Pull the bolt carrier fully rearward and lift it up and out of the receiver.
5. Separate the bolt and its tilting locking block from the carrier.
   Tip: Note the locking block orientation — it tilts to lock and only fits one way.
6. Rotate the gas tube retainer and lift the gas tube and handguard off, then withdraw the gas piston.

3. Refinish

The components the procedures above separate. Coating, masking and cure are outside this database; follow your coating system's instructions. A part the manufacturer marks "factory fit" should not be swapped or reworked.

No manufacturer statement of materials or finish is recorded. Identify each part's material before choosing prep and cure.

4. Reassemble

Reassembly

1. Install the gas piston, then the gas tube and handguard, and secure the retainer.
2. Fit the locking block to the bolt in its correct orientation and assemble the bolt to the carrier.
3. Set the carrier into the receiver rails and slide it forward.
4. Insert the recoil spring assembly and seat it.
5. Fit the receiver cover and press it down until the catch engages.
   Warning: Confirm the cover is latched.
6. Cycle the action several times and perform the function check.

5. Torque

No manufacturer torque values are recorded for this firearm.

Notes: The manufacturer's documents give no torque value. They say: "The functioning of the stock: It should be checked in order to assure that the stock is tightly secured to the receiver, is steady and does not wobble significantly." (Sa vz. 58 Military Rifle Instructions Manual (English; hosted by CZ-USA), PDF p. 27)

Fit or check on rebuild

• Return mechanism locked (audible click) — The cover pin must lock.
• Function check (safety, trigger reset, feeding, extraction) — Standard after any detail strip. No single source.
• Re-zero sights or scope — Sights and optics come off for coating, and point of impact must be re-confirmed. This is a standard check, so no source.

6. Function check

• Verify the rifle is unloaded with no magazine inserted before each step.
• Cycle the action by hand and confirm the bolt locks and returns fully to battery.
• With the selector on safe, press the trigger. The hammer or striker must not release.
• Move the selector to fire, cycle the action, and press the trigger. It should release.
• Hold the trigger back, cycle the action, and release slowly to feel the disconnector reset.
• Confirm the magazine seats and locks positively, and that any hold-open engages on an empty magazine.
• Confirm the bolt holds open on an empty magazine — a feature the AK lacks.

If any check fails, the firearm is not safe to fire. Stop and see a licensed gunsmith.
