Model-specific safety
- The safety lever also covers the charging handle slot. With the lever up on SAFE the bolt cannot travel far enough to inspect the chamber properly — rotate it down before clearing.
- The magazine rocks in and out and is not released by a button. Rock it forward and out.
- The recoil spring assembly is under compression and springs rearward when the dust cover is removed.
- Gas system parts are extremely hot after firing.
- Surplus ammunition may be corrosively primed. Clean with a water-based solvent the same day you shoot.
Under spring tension
- Recoil spring assembly
- Magazine spring

Shop difficulty
Shop tier 2 Tier 2 — moderate among rifles and carbines, for the full job: strip to the parts that get coated and put it back together working. An AKM-pattern Romanian rifle, so the shop job is the AK fire-control group. A WASR owner spent two hours routing the pin-retaining spring, which fits several ways but is right only one way. The hammer spring is strong enough to injure, and an MDShooters owner found the spring unlatched after refinishing. There is no timing.
Parts: 66 numbered parts (stand-in: Mitchell Arms 'AK-47 Autoloading Rifle' (semi-automatic Yugoslav-made AK import, same AK/AKM-pattern action as the Romanian WASR-10) per the Gun Digest exploded drawing legend, keys 1-66, in), from The Gun Digest Book of Exploded Gun Drawings (975 isometric views) — Mitchell Arms 'AK-47 Autoloading Rifle' — Gun Digest Books / Krause Publications (scan on archive.org), p. book p. 714 (PDF page 715) archive.org [12].
Bench time: about 45 min to strip, 75 min to rebuild (estimate). AK fire-control group, bolt, furniture, gas tube, rear sight.
Small parts: 7 pins, 13 springs, 3 detents or plungers (counted by name in the same legend (all 66 keys, line items). Pins: 2 rear night sight pin, 5 magazine latch pin, 9 extractor pin, 28 hammer and trigger pin, 37 folding stock hinge pins, 45 front nigh)
What comes off for coating
- Receiver: dust cover, recoil spring assembly, bolt carrier and bolt, retaining spring (shepherd's hook) or plate, hammer, trigger, disconnector and springs, safety selector, magazine catch, rear sight leaf — AK trigger pin punch / slave pin
- Bolt: firing pin retaining pin, firing pin, extractor pin, extractor, spring
- Furniture: upper/lower handguard and retainer, pistol grip screw, buttstock screws, gas tube (lever)
Special tools
- AK fire-control slave pins or punches — Hammer and trigger pins
- AK front sight tool — If the front sight post is moved
Known pain points
- The hammer/trigger-pin retaining spring has three possible anchor points and only one correct routing. It is found by trial fitting the whole group. (reassembly)
Owners report: AK Reassembly - It Took A Lot Of Wriggling — Ballseye's Boomers (owner blog) ballseyesboomers.blogspot.com [11] — “It must have taken me a good 2 hours before I got it figured out. There are three possible anchor points for the retainer spring of which you must use at least two with any spring for an AK.” - The hammer spring legs are wrapped round the hammer under tension to clear the pins and spring loose during fitting. (reassembly)
Owners report: AK Reassembly - It Took A Lot Of Wriggling — Ballseye's Boomers (owner blog) ballseyesboomers.blogspot.com [11] — “A few times, while fiddling with the hammer, the hammer spring (see the 5th pic), the ends of which are wrapped around the hammer to keep them out of the way while working, sprung!”
Fit or check on rebuild
- Retaining spring in both pin grooves — An unlatched spring lets the trigger pin back out.
- Dust-cover tab through the cover — Otherwise the cover comes off.
- 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.

Procedures
Clear and Make Safe
Clear & Make Safe- Point the muzzle in a safe direction and keep your finger off the trigger.
- Rotate the safety lever down to the fire position so the charging handle can travel fully rearward.WarningWith the lever on SAFE, bolt travel is deliberately restricted and you cannot properly inspect the chamber.
- Rock the magazine forward and out of the magazine well.Removed at this step:
Magazine - Pull the charging handle fully to the rear and hold it there. Look into the chamber and the magazine well.
- Physically feel the chamber to confirm it is empty.WarningMost AK variants have no bolt hold-open, so you must hold the bolt back yourself. Keep fingers clear when you release it.
- Ease the bolt forward and remove all live ammunition from the work area.
Field Strip
Field Strip- Complete the Clear and Make Safe procedure.
- Press in the recoil spring guide rod tab protruding through the rear of the dust cover.
- Lift the rear of the dust cover up and pull it back and off.WarningThe recoil spring assembly is compressed behind it. Keep a hand over the rear of the receiver.Removed at this step:
Dust cover - Push the recoil spring assembly forward to clear its seat, then lift it out.Removed at this step:
Recoil spring assembly - Pull the bolt carrier fully rearward to the cutout in the receiver rails and lift it up and out.Removed at this step:
Bolt carrier and bolt - Rotate the bolt to unlock it from its cam track and pull it forward out of the carrier.Removed at this step:
Bolt - Rotate the gas tube lever upward until vertical, then lift the gas tube and upper handguard off.Removed at this step:
Gas tube and upper handguard
Reassembly
Reassembly- Set the gas tube and upper handguard into the front trunnion recess, seat the rear, and rotate the lever down to lock.
- Insert the bolt into the front of the carrier and rotate it so its lug engages the cam track.
- Set the carrier into the receiver rails with the bolt forward, engage the gas piston into the gas tube, and slide it forward.
- Set the recoil spring assembly into the carrier channel and push it forward until the guide rod seats.
- Set the front lip of the dust cover into its recess, then press the rear down until the guide rod tab snaps through its hole.WarningIf the tab is not protruding through the dust cover, the cover will come off under recoil.
- Cycle the action several times and perform the function check.
Torque specifications
No sourced torque values from the manufacturer are recorded for this firearm. Where a fastener has a specified torque — action screws, scope bases, muzzle devices, barrel nuts — get it from the manufacturer or a gunsmith rather than estimating it.
What the manufacturer does say: The manufacturer's documents give no torque value. They say: "When tightening or loosening screws, hold the screwdriver firmly to prevent damage to the screw heads." (WASR (Century) owner's manual (older edition) — archive.org 'gunmanual_Century_Wasr', PDF p. 3)

Materials and factory finish
As stated by Century Arms. Prep, masking and cure depend on these; a polymer or aluminium part, a nitrided or anodised finish, and a blued steel part are each a different job. Variants with other finishes may exist — check the maker's page for the exact SKU on the bench.

Function check
- Verify the rifle is unloaded with no magazine inserted before each step.
- With the safety lever on SAFE, confirm bolt travel is restricted and the trigger does nothing.
- Rotate the safety to FIRE, charge the rifle, and press the trigger. The hammer should fall.
- Hold the trigger back, charge the rifle, and release slowly — you should hear the disconnector click.
- Confirm the dust cover is locked down and the recoil spring tab protrudes through it.
- Confirm the magazine rocks in and locks positively.
Maintenance
Lubrication points
- Bolt lugs and body
- Carrier rails
- Cam track in the carrier
- Gas piston (a light film only)
- Hammer and trigger pivots
Cleaning notes
Corrosive surplus primers leave salts that rust a bore within days. Flush the bore, gas tube, piston, and bolt face with hot soapy water or a water-based solvent the same day, dry completely, then oil. Keep the firing pin channel dry — a firing pin held forward by congealed grease causes slam fires.
Suggested inspection interval: roughly every 1000 rounds. This is a general guideline, not a manufacturer specification.
Wear parts to inspect
Recoil spring · Firing pin (check it moves freely) · Extractor and spring · Gas piston · Rivets and trunnion on high-round-count rifles
Common issues
| Symptom | Likely cause | What to do |
|---|---|---|
| Dust cover flies off when firing | Recoil spring guide tab not seated through the dust cover hole | Reinstall and confirm the tab protrudes and locks. |
| Slam fires or doubling | Firing pin stuck forward in a cosmoline-packed or fouled bolt | Stop firing. Strip the bolt, clean the firing pin channel until the pin rattles freely, and reinstall dry. see a gunsmith |
| Rust days after shooting | Corrosive primer residue | Clean with a water-based solvent the same day, dry, and oil. |
