Field Strip

1. Complete the Clear and Make Safe procedure.
2. Unscrew the barrel nut and withdraw the barrel from the receiver.
3. Unscrew the receiver retaining nut on the underside of the stock and lift the receiver out.
4. Clean the bore from the breech end of the separated barrel, and clean the bolt face, chamber, and receiver interior.
5. To stow, place the receiver, barrel, and magazines into their moulded recesses in the buttstock and close the buttplate.
   Warning: Confirm every magazine is empty before stowing it.

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.

Reassembly

1. Seat the receiver into the stock and tighten the receiver retaining nut firmly.
2. Insert the barrel into the receiver and tighten the barrel nut firmly.
   Warning: Fully tighten both. Check them before every use — this joint is made and broken often.
3. Cycle the bolt several times and confirm it returns fully into battery.
4. 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: "To secure the action to the stock, hold both firmly in place and rotate the stock takedown nut in the base of the pistol grip portion of the stock until it is firmly and tight." (Henry U.S. Survival .22 Instruction Manual for All H002 Series Rifles, PDF p. 7) "Make certain that the barrel is secured very tightly to the action." (Henry U.S. Survival .22 Instruction Manual for All H002 Series Rifles, PDF p. 7)

Fit or check on rebuild

• Barrel nut and takedown nut fully tight — The joint is made and broken often; a loose barrel shifts point of impact.
• Function check: safety, trigger/sear release, disconnector and feeding with dummy rounds — Standard after any detail strip; a mis-assembled sear or disconnector can double or fail to fire.

6. Function check

• Verify the rifle is unloaded — chamber and magazine — before each step.
• Cycle the bolt by hand and confirm it travels smoothly and returns fully into battery.
• Cock the action, engage the safety, and press the trigger. The hammer must not fall.
• Disengage the safety and press the trigger. The hammer should fall.
• Confirm the magazine seats, locks, and releases cleanly.
• Confirm the barrel nut and receiver nut are both fully tight before loading.

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