- Howa Machinery limits owner disassembly: Bolt and stock removal, and the bolt sleeve/firing pin assembly off the bolt. The firing pin assembly is not to be taken apart and the trigger adjustment screws not touched.
- This work order is written for the Howa Model 1500. It is reported to cover Weatherby Vanguard (built on the same action); Legacy Sports Howa rifles — if the firearm on the bench is one of those, check the torque notes: values do not always carry over.
- No manufacturer torque values are recorded. The values listed are reported by other sources, not the manufacturer — confirm them before use.
Shop difficulty: Tier 1 of 3
About 54 action, trigger and magazine parts plus a stock held by two guard screws; the bolt strips by hand and the trigger stays a unit. The only real trap is the bolt sleeve/firing pin assembly, which Howa says stays assembled unless a gunsmith has the tool. 53 parts (Barreled action, bolt, trigger assembly, trigger guard/floorplate and magazine; the stock is not in the list). Pew-Takedown's rating, not the manufacturer's.
Bench time: strip ~20 min, rebuild ~30 min (estimate). Actual: strip ______ rebuild ______
Special tools:
- Bolt disassembly / cocking-piece tool (or shop-made wedge) — Holding the cocking piece back while the bolt sleeve unscrews
- Inch-pound torque driver — Guard screws on reassembly
Watch for:
- The bolt sleeve/firing pin assembly is held under heavy mainspring pressure; Howa says it is not to be taken apart without the gunsmith's special tool. (both; Legacy Sports International)
- Putting the bolt sleeve back needs heavy pressure and a 1/3 turn to the cocking detent; turned too far, the cocking piece snaps forward and has to be dragged back on a bench edge. (reassembly; Legacy Sports International)
- Gunsmiths strip the same action (sold as the Weatherby Vanguard) with a shop-made wedge that holds the cocking piece back while the shroud unscrews. (both; AccurateReloading.com Gunsmithing forum)
Tools
- Bore guide — Cleaning from the breech without damaging the throat or the crown.
- Hex key or screwdriver matching the action screws — Removing the barrelled action from the stock. Not needed for routine cleaning.
- Torque wrench — Reinstalling action screws to a consistent value, which is an accuracy variable on every bolt rifle.
1. Clear and 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.
- Inspect the chamber and magazine well with a light and physically confirm the chamber is empty.
Warning: Look and feel. Both, every time. - Remove all live ammunition from the work area.
2. Disassemble

Field Strip
- Complete the Clear and Make Safe procedure.
- Make sure the rifle is unloaded and put the safety ON. Howa's disassembly begins with the safety on, not off.
Warning: Wear safety glasses. The manual asks for them in case a part under spring tension escapes your grasp.
Tip: On three-position models the middle position is the one you want: safety ON with the bolt still free to open. Pushed fully rearward the safety is ON and the bolt is locked, and you will not get it out. - Lift the bolt handle and draw the bolt fully rearward.
- With the bolt part way to the rear, depress the bolt stop and withdraw the bolt rearward out of the receiver.
- Clean the bore from the breech using a bore guide, and clean the bolt face, lugs, and chamber.
Warning: Always use a bore guide.
Remove the Barrelled Action from the Stock
- 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.
Tip: They are often different lengths. - Lift the barrelled action out of the stock.
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.
| Component separated | Out | Coated | Back in |
|---|---|---|---|
| Bolt assembly | |||
| Action screws | |||
| Floorplate or magazine assembly | |||
| Stock |
No manufacturer statement of materials or finish is recorded. Identify each part's material before choosing prep and cure.
The manufacturer's full parts list (54 parts) is on the reference page.
4. Reassemble

https://www.youtube.com/watch?v=PloZ-yGZ8mc
Remove the Barrelled Action from the 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.
Warning: Inconsistent 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.
Reassembly
- Confirm the bolt is correctly assembled and the bolt head is properly oriented.
- Align the bolt with the receiver raceway and slide it forward into the action.
- Close the bolt handle and cycle the bolt several times to confirm smooth travel and correct cocking.
- Confirm the bolt release retains the bolt when the action is opened fully.
- Perform the function check.
5. Torque
No manufacturer torque values are recorded for this firearm.

Notes: Howa's M1500 manual gives no torque value for the action (takedown) screws. It says: "The longer takedown screw goes behind the trigger guard. Tighten the two takedown screws alternately until both are snug, then tighten front screw firmly; finally, tighten rear screw." (Howa Rifle Instruction & Safety Manual, p. 25). The 50–55 in-lb figure sometimes quoted for the Howa 1500 comes from Howa's separate Series 1500 Mini Action manual ("torque action bolts to 50 to 55 in-lbs. DO NOT EXCEED 55 IN-LBS. OR DAMAGE TO THE FLOOR PLATE MAY RESULT.", p. 23). The Mini Action is a shorter action with its own trigger guard and floor plate, so that value is not recorded here for the standard Model 1500.
Fit or check on rebuild
- Action screw torque — Bedding and accuracy depend on consistent guard-screw torque
- Bolt sleeve in cocked position — The cocking piece must be in its detent or the bolt will not go back in
- Trigger/safety function — Trigger unit is not to be adjusted; check safety and let-off after reassembly
6. Function check
- 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.
If any check fails, the firearm is not safe to fire. Stop and see a licensed gunsmith.
If it won't go back together
| Symptom | Cause | Fix |
|---|---|---|
| The bolt will not come out of the receiver. | On a three-position safety the lever is pushed fully rearward, which locks the bolt. | Move the safety to the MIDDLE position — still ON, but the bolt is free to open — then depress the bolt stop with the bolt part way back. |
