Work order — Remington Nylon 66

Taking the firearm apart for a job such as refinishing, and putting it back together to specification. Generated from the Pew-Takedown entry last updated 2026-10-29. Confidence: low.

Shop difficulty: Tier 3 of 3

About 59 key numbers (79 rows), but the action lives inside a moulded nylon stock-receiver with small loose parts under a stamped cover; gunsmiths report it is the rifle most often brought in disassembled 'in a coffee can' that owners cannot reassemble, parts are scarce, and screws strip easily into nylon. Widely reported miserable to reassemble. 59 parts (Remington Nylon 66 parts list (RF 22), standard model; 59 key numbers, 79 rows incl. Apache/Black Diamond variant rows and accessories; Gallery Special sub-list left out). Pew-Takedown's rating, not the manufacturer's.

Bench time: strip ~60 min, rebuild ~110 min (estimate). Actual: strip ______ rebuild ______

Special tools:

• Punch set incl. small pin punches — Trigger group pins
• Fitted screwdrivers — Screws into nylon (strip easily)

Watch for:

• Gunsmiths report the Nylon 66 is the gun most often brought in as a box of parts that the owner (and sometimes a 'gunsmith') could not put back together. (reassembly; Accurate Reloading Gunsmithing Forum)
• Removing the receiver cover risks losing small parts, and few gunsmiths now have the experience or parts to fix one. (both; Accurate Reloading Gunsmithing Forum)

1. Clear and make safe

1. Point the muzzle in a safe direction and keep your finger off the trigger.
2. Engage the safety.
3. Open the loading port in the buttplate and withdraw the inner magazine tube from the buttstock.
   Warning: The magazine spring is compressed inside. Withdraw it under control.
4. Tip the rifle muzzle-down so any remaining cartridges roll out of the buttstock tube, and count them out.
5. Cycle the bolt several times to eject any chambered round and confirm nothing further feeds.
6. Hold the bolt open and inspect the chamber with a light.
   Warning: Check the chamber and confirm the buttstock tube is empty.
7. Physically confirm the chamber is empty and remove all live ammunition from the work area.

2. Disassemble

Field Strip — Bolt Access Only

1. Complete the Clear and Make Safe procedure.
2. Remove the receiver cover screws and lift the sheet-metal receiver cover off the moulded receiver.
   Warning: Note the cover orientation. It carries the rear sight on many rifles.
3. Withdraw the bolt and recoil spring assembly rearward out of the receiver.
   Warning: The recoil spring is under tension and the assembly is not captive.
4. Clean the chamber, bore, bolt face, and the accessible receiver interior.
5. Stop here. Going further into the fire control and feed mechanism is where Nylon 66 reassembly becomes genuinely difficult.
   Warning: If the rifle is malfunctioning, take it to a gunsmith with a parts diagram rather than exploring.

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.

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 (79 parts) is on the reference page.

4. Reassemble

Reassembly

1. Insert the recoil spring assembly and bolt into the receiver and seat them.
2. Cycle the bolt by hand and confirm free travel and full return to battery before closing the receiver.
3. Fit the receiver cover in its correct orientation and install its screws.
   Warning: Do not overtighten screws into the nylon receiver.
4. Reinstall the inner magazine tube and perform the function check.

5. Torque

No manufacturer torque values are recorded for this firearm.

Fit or check on rebuild

• Receiver cover screws just snug — Over-tightened cover screws make the bolt stick and strip the nylon.
• 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 inner magazine tube latches securely in the buttstock.

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