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.

Winchester Repeating Arms limits owner disassembly The maker's own procedure goes as far as: Bolt removal, and unscrewing the bolt sleeve/firing pin assembly from the bolt (not disassembling the firing pin assembly further than Figure 22).. Winchester tells owners never to take the Model 70 apart further than the manual explains; further disassembly for service or cleaning is for a qualified gunsmith or Winchester's Arnold, Missouri service facility.

Model-specific safety

Removing the magazine does not clear the chamber. Cycle the bolt and check the chamber directly.
The bolt release must be operated to withdraw the bolt. Do not force the bolt out — if it will not come, the release is not engaged or the safety is blocking it.
Clean from the breech with a bore guide. Cleaning a bolt rifle from the muzzle without a guide wears the crown and costs accuracy permanently.
Removing the barrelled action from the stock changes the bedding relationship. Reinstall the action screws to a consistent torque or the rifle will shift its zero.
Pre-1964 and current-production Model 70s use controlled-round-feed with a long claw extractor; many 1964-1992 rifles use push-feed. The two differ in how a cartridge is picked up from the magazine and in how you should handle a single round.
On a controlled-round-feed rifle, do not drop a round directly into the chamber and close the bolt — the claw extractor is designed to pick the case rim up from the magazine, and single-loading can stress it.

If it will not go back together

Common ways this firearm resists reassembly, and what is actually wrong. Forcing a part that will not seat is how firearms get damaged.

The bolt will not come out of the receiver.

Why The safety is in the wrong position, or the firing pin is not cocked.

Fix Put the safety in its INTERMEDIATE position — not fire — and confirm the cocking indicator protrudes at least 1/8 in, then depress the bolt stop and withdraw the bolt.

Tools

Tool	Required	Used for	Substitute
Bore guide	Yes	Cleaning from the breech without damaging the throat or the crown.	There is no good substitute. A rod run into an unguided chamber scrapes the throat.
Hex key or screwdriver matching the action screws	Optional	Removing the barrelled action from the stock. Not needed for routine cleaning.
Torque wrench	Optional	Reinstalling action screws to a consistent value, which is an accuracy variable on every bolt rifle.

Shop difficulty

Shop tier 1 Tier 1 — easy among rifles and carbines, for the full job: strip to the parts that get coated and put it back together working. A classic two-screw bolt rifle with a simple bolt and a bolt sleeve that unscrews. The traps are small: the sleeve is stiff to turn on a new rifle, the claw extractor must be aligned, the three-position safety position matters, and bolts are serial-matched for headspace.

Parts: 50 numbered parts (stand-in: pre-1964 controlled-round-feed Winchester Model 70 and 70 Featherweight per the Gun Digest exploded drawing legend (courtesy James M. Triggs), keys 1-50: receiver, barrel, sights, bolt with ), from The Gun Digest Book of Exploded Gun Drawings (975 isometric views) — Winchester 'Model 70 and 70 Featherweight Bolt-Action Rifle' — Gun Digest Books / Krause Publications (scan on archive.org), p. book p. 967 (PDF page 968) archive.org [4].

Bench time: about 30 min to strip, 45 min to rebuild (estimate). Stock and bottom metal, bolt sleeve, firing pin and safety, extractor, bolt stop. The trigger is left as a unit.

Small parts: 7 pins, 9 springs, 2 detents or plungers (counted by name in keys 1-50 (line items). Pins: 18 breechbolt sleeve lock pin, 22 safety lock stop pin, 25 ejector pin, 29 trigger pin, 37 sear pin, 43 magazine cover hinge pin, 48 magazine cover cat)

What comes off for coating

Stock / bottom metal: action screws, trigger guard / floorplate, magazine box, spring, follower, swivel studs, recoil pad or butt plate
Bolt: firing pin assembly (shroud, cocking piece, mainspring), extractor, ejector and spring, bolt sleeve and sleeve lock, three-position safety and plunger
Receiver: trigger assembly (as a unit), bolt stop and spring, safety (if receiver-mounted), scope bases / iron sights

Special tools

padded vise — Turning a stiff bolt sleeve
torque driver — Action screws

Known pain points

With the firing pin down, the bolt sleeve has to be turned back to its notch. On a new rifle it may need the firing pin gripped in a padded vise. (reassembly)
Source: Winchester Model 70 Bolt-Action Rifle Owner's Manual — Winchester Repeating Arms winchesterguns.com [1] — “On a new gun where surfaces are not yet burnished from use, it may be difficult to rotate the bolt sleeve by hand. If so, carefully grasp the lower section of the firing pin in a padded vise, pull and turn.”
The claw extractor has to be lined up with the right-hand lug or the bolt will not enter, and the safety must be in its intermediate position. (reassembly)
Source: Winchester Model 70 Bolt-Action Rifle Owner's Manual — Winchester Repeating Arms winchesterguns.com [1] — “Make sure the claw extractor is perfectly lined up with the right-hand locking lug.”
Bolts are fitted and serial-etched for headspace. In a multi-gun shop job, bolts must never be swapped between rifles. (reassembly)

Procedures

Clear and Make Safe

Clear & Make Safe

Point the muzzle in a safe direction and keep your finger off the trigger.
Place the safety in the on position.
Lift the bolt handle and draw the bolt fully rearward, extracting and ejecting any chambered round.
Unload the magazine: on a hinged floorplate rifle press the floorplate latch and let the rounds fall out; on a detachable magazine rifle remove the magazine; on a blind magazine cycle the bolt to feed and eject each round.
Removed at this step: Magazine contents
Inspect the chamber and magazine well with a light and physically confirm the chamber is empty.
WarningLook and feel. Both, every time.
Remove all live ammunition from the work area.

Field Strip

Bolt removal is the whole of routine maintenance on a bolt rifle. The bore cleans from the breech with the bolt out.

Complete the Clear and Make Safe procedure.
Confirm the firing pin is cocked — the cocking indicator should protrude at least 1/8 in from the rear of the bolt sleeve. If it is not cocked, cock it with the rifle unloaded and the muzzle in a safe direction by raising and lowering the bolt handle.
TipIf the indicator will not protrude, the bolt has been partially disassembled. Sort that out before going further.
Place the safety in its INTERMEDIATE position.
WarningNot the fire position. The Model 70's three-position safety has a middle detent that locks the firing pin while still letting the bolt be worked, and that is the position the manual specifies for bolt removal.
Raise the bolt handle and draw the bolt fully to the rear.
Depress the bolt stop at the left rear of the receiver and remove the bolt.
Removed at this step: Bolt
Clean the bore from the breech using a bore guide, and clean the bolt face, lugs, and chamber.
TipWinchester notes it is always advisable to remove the bolt before cleaning.
Stop here for routine maintenance.

Reassembly

Use only this rifle's own bolt.
WarningThe bolt is selected and fitted at the factory for correct headspace and is etched with the rifle's serial number. Never interchange bolts. If yours is lost or damaged, the rifle goes back to the factory for a fitted replacement.
Place the safety in its intermediate position and check that the claw extractor is perfectly lined up with the right-hand locking lug.
Insert the bolt into the receiver with its lugs aligned with the lug tracks.
Push the bolt fully forward and lower the handle to the locked position. The safety can now be operated.
Confirm the safety is in either the intermediate or the rear on-safe position, then perform the function check.

Remove the Barrelled Action from the Stock

Detail Strip tools required

For a deep clean or bedding work. Not routine maintenance.

Verify the rifle is unloaded and remove the bolt and magazine.
Remove the action screws from the bottom of the stock, noting which screw came from which hole.
TipThey are often different lengths.
Removed at this step: Action screws Floorplate or magazine assembly
Lift the barrelled action out of the stock.
Removed at this step: Stock
To reinstall, seat the action in the stock, start both screws by hand, then tighten the front screw first and the rear second to a consistent torque.
WarningInconsistent action screw torque is one of the most common causes of a rifle that will not hold zero. Consult your stock maker’s specification rather than guessing.

Torque specifications

Use a calibrated torque driverValues are the manufacturer's, shown in the unit it gives first; conversions are calculated and rounded. Tighten to the stated value — not "until it feels right" — and follow any sequence noted.

Materials and factory finish

As stated by Winchester Repeating 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.

Verify the rifle is unloaded and the magazine is empty before each check.
Cycle the bolt and confirm it cocks and closes fully into battery.
With the action cocked, engage the safety and press the trigger. The firing pin must not release.
Disengage the safety without touching the trigger. The firing pin must not release.
Press the trigger and confirm the firing pin releases cleanly.
Confirm the bolt release retains the bolt.
Load dummy rounds and confirm they feed from the magazine and eject cleanly.

Maintenance

Lubrication points

Bolt lugs and the locking recesses
Bolt body where it rides in the raceway
Cocking cam surfaces
Extractor

Cleaning notes

Clean from the breech with a bore guide. Do not over-lubricate the firing pin assembly — heavy oil there congeals in cold weather and causes light strikes. Keep the chamber dry and free of oil before shooting, since oil in a chamber raises bolt thrust.

Suggested inspection interval: roughly every 500 rounds. This is a general guideline, not a manufacturer specification.

Wear parts to inspect

Extractor · Ejector and spring · Bolt lugs · Firing pin spring · Crown (inspect for cleaning rod wear)

Common issues

Symptom	Likely cause	What to do
Group size opens up after cleaning or transport	Action screw torque changed	Retorque the action screws consistently, front first.
Light strikes in cold weather	Heavy or congealed oil in the firing pin assembly	Degrease the firing pin assembly and run it dry or with a light synthetic lubricant.
Bolt will not withdraw	Bolt release not operated, or the safety is blocking it	Move the safety to fire and operate the release. Do not force the bolt.
Extractor damage after single-loading	Dropping rounds into the chamber on a controlled-round-feed rifle	Feed rounds from the magazine so the claw picks up the rim as designed. see a gunsmith

Notes: CORRECTED on 2026-09-14 against the factory manual. The entry said to move the safety to the fire position. The Model 70's three-position safety has an intermediate detent that locks the firing pin while still allowing the bolt to be worked, and that is the position the manual specifies — telling someone to go to fire instead gives up a safety for no reason. Also added the manual's requirement that the firing pin be cocked first, the claw extractor alignment on reinstallation, and its warning that Model 70 bolts are headspace-fitted and serial-etched and must never be interchanged. Model 70 production spans pre-1964, 1964-1992 push-feed, and later controlled-round-feed eras with meaningful differences in extractor and feeding. Identify which your rifle is before ordering parts or single-loading it.
