WASR-10

field strip ~2 min · reassembly ~2 min · detail strip ~40 min

Before you begin Verify this firearm is unloaded. Remove the magazine or empty the cylinder or tube, lock the action open, and check the chamber both by sight and by touch. Keep the muzzle in a safe direction and remove all live ammunition from your work area.
What Century Arms says about disassembly Century's WASR manual gives an owner field strip (top cover, recoil spring assembly, bolt carrier and bolt, gas tube with upper handguard) and says no further disassembly is generally needed for routine maintenance; it does not forbid going further. (WASR Type Sporting Rifles Owner's Manual, Cal. 7.62x39mm (Century, ©2009; listed as 'GP WASR-10 Hi-Cap Semi-Auto Rifle') — Century International Arms, Inc., p. 10 centuryarms.com [5])

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)

Procedures

Clear and Make Safe

Clear & Make Safe
  1. Point the muzzle in a safe direction and keep your finger off the trigger.
  2. 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.
  3. Rock the magazine forward and out of the magazine well.
    Removed at this step: Magazine
  4. Pull the charging handle fully to the rear and hold it there. Look into the chamber and the magazine well.
  5. 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.
  6. Ease the bolt forward and remove all live ammunition from the work area.

Field Strip

Field Strip
  1. Complete the Clear and Make Safe procedure.
  2. Press in the recoil spring guide rod tab protruding through the rear of the dust cover.
  3. 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
  4. Push the recoil spring assembly forward to clear its seat, then lift it out.
    Removed at this step: Recoil spring assembly
  5. 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
  6. Rotate the bolt to unlock it from its cam track and pull it forward out of the carrier.
    Removed at this step: Bolt
  7. 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
  1. Set the gas tube and upper handguard into the front trunnion recess, seat the rear, and rotate the lever down to lock.
  2. Insert the bolt into the front of the carrier and rotate it so its lug engages the cam track.
  3. Set the carrier into the receiver rails with the bolt forward, engage the gas piston into the gas tube, and slide it forward.
  4. Set the recoil spring assembly into the carrier channel and push it forward until the guide rod seats.
  5. 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.
  6. 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)

Reported by other sources — not the manufacturer

Not a manufacturer specificationThese values come from the people and publications named beside each one, not from Century Arms. They are recorded with who said them and their exact words so you can judge them — not as a recommendation. Confirm any of them with the manufacturer or a licensed gunsmith before you put a wrench on your firearm; a wrong value can crack a stock, strip a thread or loosen a muzzle device.

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

After every reassemblyPerform these checks on a verified-unloaded firearm. If any check fails, the firearm is not safe to fire — stop and see a licensed gunsmith.

Maintenance

Lubrication points

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
