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.

Marlin Firearms limits owner disassembly The maker's own procedure goes as far as: Lever off, bolt assembly pulled from the receiver, ejector lifted out, butt stock removed. Hammer and trigger assembly stay in the receiver.. Marlin says lever-action centerfire rifles should not be disassembled beyond what the manual describes except by the factory, and that the trigger and hammer are cleaned as a unit without removing them from the receiver.

Specifications

Manufacturer: Marlin Firearms
Origin: United States
Category: Rifle
Action: Lever action
Calibers: .30-30 Winchester, .35 Remington, .44 Magnum (Model 1894)
Capacity: 6 rounds in the tube magazine, typical
Production: 1948–present (in-production)
Also known as: 336C, 336W, Marlin 30-30

Model-specific safety

A tube magazine is unloaded by cycling rounds through the action one at a time. There is no floorplate. Cycle until nothing more feeds, then verify the chamber and look into the loading gate.
The hammer has a half-cock position. Half-cock is not a safety — it is a hammer rest. Later rifles add a crossbolt safety; use it, and still verify the chamber.
Lowering the hammer by hand on a chambered round is how people put holes in things. Unload first.
Tube magazines and pointed bullets do not mix. In a tube magazine, a spitzer bullet tip rests on the primer of the round ahead of it, and recoil can set it off. Use flat-nose or approved polymer-tip ammunition only.
Do not force the lever. If the action binds, something is out of position — usually the bolt or the carrier.

Shop difficulty

Shop tier 3 Tier 3 — hardest among rifles and carbines, for the full job: strip to the parts that get coated and put it back together working. About 64 pieces with the bolt, carrier and lever kept as assemblies; Marlin says centerfire lever actions should not be stripped past the field strip except by the factory, and the hammer, magazine and sear/trigger springs all have to be controlled. Lever-action internals put it at the hard end of the rifle group, though Marlin is simpler than a Winchester 94.

Parts: 60 numbered parts (Complete rifle (one list for 1895 and 336; bolt, carrier, ejector, lever as assemblies; sights vary by series)), from Marlin Model 1895 and Model 336 Lever-Action Rifles Instruction Manual — Sturm, Ruger & Co., Inc., p. 55 marlinfirearms.com [1].

Bench time: about 50 min to strip, 80 min to rebuild (estimate). Estimate: lever, bolt (firing pins, extractor), ejector, buttstock, hammer and mainspring, trigger guard plate (trigger, sear, trigger safety blocker, springs), carrier and screw, loading gate, cross-bolt safety (detent ball and spring), magazine tube/spring, bands and sights. Rebuild longer: hammer spring and trigger plate springs, carrier and lever/bolt timing through the stroke, function check.

Small parts: 4 pins, 3 springs, 3 detents or plungers (counted from the manufacturer's parts list (one per key number unless a quantity is given))

What comes off for coating

Action (receiver): finger lever and lever screw, breech bolt assembly (front/rear firing pin, extractor), ejector, carrier and carrier screw, loading gate and screw, locking bolt, cross-bolt safety, detent screw, ball and spring
Trigger guard plate / hammer: hammer, hammer screw, hammer strut and spring, adjusting plate, trigger, sear, trigger safety blocker, trigger spring and pins, trigger guard plate and screws — drift punch
Barrel and furniture: magazine tube, plug, spring, follower, forearm and bands, buttstock and tang screw, front/rear sights — brass punch for dovetail sights

Special tools

Gunsmith (hollow-ground) screwdrivers — Lever, tang, carrier, hammer and loading gate screws, which burr easily
Pin punches — Trigger, trigger spring and hammer strut pins
Brass/nylon drift or sight pusher — Dovetail rear sight and front sight

Known pain points

Marlin tells owners not to strip a centerfire lever action past the field strip (lever, bolt, ejector, buttstock); the trigger plate, hammer, carrier and safety work behind it is factory work. (both)

Procedures

Clear and Make Safe

Clear & Make Safe

Point the muzzle in a safe direction and keep your finger off the trigger.
If the rifle has a crossbolt safety, engage it.
Work the lever fully open and closed repeatedly, catching each cartridge as it ejects, until no more feed from the magazine.
With the lever open, inspect the chamber and the carrier with a light, and look into the loading gate to confirm the magazine tube is empty.
WarningCheck the chamber, the carrier, and the tube. A lever gun can hold a round in any of the three.
Physically confirm the chamber is empty, then remove all live ammunition from the work area.

Field Strip — Lever and Bolt Removal

Field Strip tools required

Enough for cleaning the bore from the breech, which is the main practical benefit of the Marlin's solid-top, side-eject receiver.

Complete the Clear and Make Safe procedure, and put on eye protection. Work on a bench covered with an old blanket or a piece of shallow-nap rug, and keep a shoebox to drop parts into as they come off.
WarningThe manual asks for eye protection and warns that parts under spring tension — the hammer, the tubular magazine components, the sear and trigger assembly — will jump when released.
TipA covered bench stops the rifle sliding and catches pins and springs before they reach the floor.
Open the action by rotating the lever downward and forward until the bolt is fully rearward.
Engage the safety by moving the safety button fully to the shooter's right. The red band must not be visible.
TipThe manual's sequence uses the safety button, not the hammer's half-cock notch.
Look into the ejection port and check the chamber, loading port, and magazine for cartridges.
Rotate the lever halfway through its stroke, so the bolt sits about halfway closed.
TipThe lever mounting screw will not clear with the lever fully open or fully closed.
Remove the lever mounting screw by turning it counter-clockwise.
Removed at this step: Lever mounting screw
Pull the lever down and out of the bolt assembly and receiver.
Removed at this step: Finger lever
Lay the receiver flat with the ejection port facing up, then pull the bolt assembly rearward out of the receiver.
WarningEjection port up. Turn the receiver over and the ejector moves out of position.
Removed at this step: Bolt assembly
Lift the ejector out through the ejection port with a pair of pliers, taking care not to damage it.
Removed at this step: Ejector
Stop here for cleaning. If you also need the butt stock off, remove the tang screw behind the hammer and pull the stock straight back off the receiver.
WarningLever-action centrefire rifles should not be disassembled beyond what the manual describes, except by the factory.

Reassembly

Check that the barrel is free of obstructions and the chamber is empty before the bolt goes back in. Eye protection stays on.
Insert the ejector into the ejector slot with its closed end to the rear. The post must rest in the hole at the rear end of the slot, and the flat spring must sit in the slot pointing toward the muzzle.
TipGet this orientation wrong and the rifle will not eject. Check it before the bolt goes in.
Check that the locking bolt is down, in the unlocked position. If it is up, push it down from the rear of the receiver with a small screwdriver.
TipThis is the step people miss. A locking bolt left up will not let the bolt assembly seat.
Hold the hammer down and insert the bolt assembly into the rear of the receiver with the extractor to the shooter's right.
TipBoth hands are busy here. Keep the rifle flat so the ejector stays in its slot as the bolt goes past it.
Push the bolt forward about halfway to closed — the bolt should occupy about half the ejection port.
From the bottom of the receiver, insert the lever up through the lever slot in the bolt assembly until the lever's mounting hole lines up with the receiver's.
Insert the lever mounting screw from the shooter's right and tighten it hand tight. Do not over-tighten.
If the butt stock was removed, fit it onto the rear of the receiver and tighten its mounting screw snug. Do not over-tighten.
Check that all receiver screws are tight — three on the shooter's right (hammer, carrier, loading gate) and the trigger guard plate support screw on the left — without attempting to remove or loosen them.
TipThe manual gives Torx bit sizes and torque figures for these; use them rather than feel.
Leave the safety engaged, then perform the function check.

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.

Notes: From the torque table in the Ruger-made Marlin Model 1895 and Model 336 instruction manual (p. 58), which covers rifles fitted with Torx screws — Ruger's words are "models so equipped". Earlier Marlin rifles with slotted screws are not covered. Every value is a range in inch-pounds; key numbers refer to the exploded view on p. 56. Read this before refinishing: the reassembly procedure (p. 41) tells owners to tighten the four receiver screws — hammer, carrier and loading gate screws on the right, trigger guard plate support screw on the left — without over-tightening, and says "Do not attempt to remove or loosen these screws." Their values are listed here because Ruger publishes them, not as an invitation to take them out.

Reported by other sources — not the manufacturer

Not a manufacturer specificationThese values come from the people and publications named beside each one, not from Marlin Firearms, and where they differ from the manufacturer's values above, the manufacturer wins. 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.

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.

Completely unload the rifle and check the chamber, loading port, and magazine through the ejection port before testing anything.
Open the action fully and engage the safety.
Rear firing pin test: push on the rear firing pin from the bottom of the bolt, then release. It must return to the downward, disconnected position without hesitation. If it does not, the rifle is not safe to fire — it goes back to the manufacturer, not to the range.
Look into the ejection port and confirm the firing pin tip is NOT protruding from the bolt face. A protruding firing pin means the rifle is not safe.
With the safety engaged, cycle the action fully open and fully closed.
Disengage the safety and, with the rifle pointed in a safe direction, pull the trigger fully rearward. The hammer should release.
Confirm the trigger returns completely forward each time it is released.
Cycle the action and repeat the last three steps several times.

Cleaning notes

Clean from the breech with a bore guide. Keep the inside of the magazine tube dry rather than oiled — oil there collects fouling and slows the follower.

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

Wear parts to inspect

Extractor · Ejector and its spring · Carrier · Loading gate spring · Magazine spring

Common issues

Symptom	Likely cause	What to do
Lever will not rotate back into place	Bolt not positioned so the lever lug can engage	Adjust the bolt position slightly and rotate the lever in without force.
Rounds jam on the carrier while cycling	Short-stroking the lever, or a worn carrier	Work the lever fully open and fully closed. If it persists with a full stroke, have the carrier inspected. see a gunsmith
Rifle will not fire even though the hammer falls	Lever not fully closed, engaging the lever safety	Close the lever completely. This safety is by design.

Notes: Verified and expanded on 2026-09-14 against the Ruger-era factory manual. The outline was right but the entry was missing the steps that make it work: rotating the lever halfway before the mounting screw will clear, laying the receiver ejection-port-up so the ejector stays put, and removing the ejector at all. Reassembly was missing three requirements — ejector orientation, the locking bolt being down, and holding the hammer down as the bolt goes in — without which the rifle does not go back together. The function check now carries the manual's rear firing pin and protruding firing pin tests, both of which are pass/fail conditions for whether the rifle is safe to fire at all. Marlin lever guns were produced across many decades, and Remington-era and Ruger-era production differ in detail. Crossbolt safeties were added in the 1980s. Confirm screw locations and safety features against the manual for your rifle.
