Using the Firearm


Read detailed instructions about loading, unloading, and other operation of your Self-Loading Rimfire Rifle With Clip Magazine (22 L.R. and 17 Mach 2).


The instructions in this shaded section apply to the 70PSS only. The rest of this manual applies to all models.

How to Assemble the 70PSS

The 70PSS was shipped “taken-down” in two parts. The stock, action and magazine comprise one part, the barrel the other (See 1).

Match the flat surface on the rear (chamber) end of the barrel with the flat surface in the front end of the receiver, and insert the barrel into the receiver as far as it will go. (See 2).

Turn the knurled takedown nut clockwise with your fingers until tight. If you are going to shoot extensively, tighten the nut securely with the spanner wrench (provided), or a coin (See 3).

  • WARNING: Check the takedown nut frequently to be sure it remains tight. If it loosens, the rifle may not fire.

To disassemble the 70PSS for reinsertion into its case, reverse the above instructions.

Transportation and Storage Instructions for the 70PSS

If your 70PSS will be subjected to rough handling while in its case, we recommend that you use the foam insert provided, for maximum protection.

Do not store the 70PSS in its case for long periods of time, since moisture can be trapped and condense inside, causing rust or corrosion. For long term storage, it should be lightly oiled and kept in a dry, ventilated area, under lock and key.


Before You Use This Firearm

It is very important that you read and understand this manual before using your firearm. Warnings should be read and heeded carefully. Also follow The Ten Commandments of Firearm Safety.

  • WARNING: Marlin firearms are designed and manufactured to handle standard factory-loaded ammunition which conforms to SAAMI (Sporting Arms and Ammunition Manufacturers’ Institute Inc.) standards with dependability and safety. Due to the many bullet and load options available, the element of judgement involved, the skill required, and the fact that serious injuries have resulted from dangerous handloads, Marlin does not make any recommendations with regard to handloaded ammunition.
  • WARNING: It is a violation of federal law to alter or deface the serial number of any firearm.
  • WARNING: Your rifle was shipped completely assembled (except the 70PSS) and should not be used or disassembled without fully reading and understanding the instructions in this Owner's Manual.

How to Operate the Safety

  • WARNING: Prior to firing, know and understand the operation of the safety by practicing with the rifle unloaded.

The safety mechanism is a round button located behind the trigger. To put your rifle on SAFE, hold it in the normal shooting position, pointed in a safe direction, and push the safety button from left to right as far as it will go. The safety is now on SAFE (See A).

To move the safety to the FIRE position, push the safety button from right to left as far as it will go. A red ring around the safety button will be visible when the safety is in the FIRE position (See B). If the magazine is in place and the bolt is forward and the trigger is pulled with the safety in this position, the gun will fire.


NOTE: This rifle is equipped with a magazine disconnector. It will not fire if the magazine is not in place. Do not, however, use the magazine disconnector as the primary safety and never as a reason for unsafe firearm handling.

  • WARNING: Never disassemble the safety. It has been correctly designed, fitted and tested, and is not reversible. Any mechanical device can fail, however, so never rely on the safety to justify careless handling. Never use a firearm with a safety that does not function properly. (See instructions for factory maintenance in this manual.)

How to Load

  • WARNING: Never attempt to load your rifle with ammunition that does not meet the cartridge designation stamped on the barrel. Use only clean, dry, factory-loaded ammunition which conforms to industry standards.

Rifles chambered for 22 L.R. ammunition:

  • WARNING: Your rifle is a self-loading .22 caliber designed for .22 Long Rifle High Velocity cartridges only (not Hyper-Velocity); it will not function with Shorts, Longs or Shot cartridges, and damage or injury may result from their use.

NOTE: Our testing has shown that the following types of 22 L.R. ammunition produce the most consistent functioning and the best accuracy in our self-loading 22 rifles:

  • CCI Mini-Mag
  • CCI Mini-Mag Hollow Point
  • Federal Classic High Velocity
  • Remington High Velocity (Not Thunderbolt)
  • Winchester Super X High Velocity

Rifles chambered for 17 Mach 2 ammunition:

Any commercially available 17 Mach 2 ammunition will function in your rifle.

  • WARNING: Before loading your rifle, always check the bore and chamber to be sure they are free of grease, oil or any other obstruction.
  • WARNING: Your self-loading rifle is not designed to be single-loaded and IT WILL NOT FIRE unless the magazine is locked in place. Always load cartridges through the magazine as directed. Never use the magazine disconnector as the primary safety or as an excuse for unsafe firearm handling.
  1. Place safety on “SAFE”.
  2. Depress the magazine release latch (See C) and remove the magazine from the rifle.
  3. Pull bolt charging handle back and hold.
  4. Push the bolt control lever up to the “OPEN” position as indicated on the trigger guard (See G).
  5. Insert up to 10 cartridges (7 for the 70PSS) as shown in D. With the rifle pointed in a safe direction, replace the loaded magazine, being sure it locks in place.
  6. Keeping fingers away from the trigger, push the bolt control lever down to the “CLOSE” position as indicated on the trigger guard (See H).
    NOTE: Allow bolt to slam shut freely. Do not attempt to assist the closing of the bolt with your hand.

Cocked and Ready

  1. Your self-loading rifle is cocked for firing as soon as the bolt is closed during the loading operation as described above.
  2. The rifle is ready to fire as soon as the safety is pushed to the “FIRE” (off “SAFE”) position.

How to Fire

  1. Push the safety to the “FIRE” position and, with the rifle pointed at the target, squeeze the trigger. Since your rifle is self-loading, it is ready to fire again after each shot.
  2. If you have not fired all cartridges in the magazine at the target, be sure to move the safety to the “SAFE” position until you are ready to shoot again.
  • WARNING: Because of its self-loading action, if the bolt of your rifle is completely closed, you must assume that it is cocked and loaded.

How to Unload

  • WARNING: Before you unload, be sure that the safety is on “SAFE” and the rifle is pointed in a safe direction. Also, keep your fingers away from the muzzle of the rifle.
  1. Depress the magazine release latch as shown in C and pull the magazine out of the rifle.
  2. Pull the bolt to the rear and lock it in the open position (see “Manual” Bolt Hold-Open Feature.)
  3. Inspect the chamber and magazine well.
    NOTE: If the bolt is in the closed position, pull the bolt charging handle back manually to eject the cartridge left in the chamber (See F).

Bolt Hold-Open Features

Automatic “Last Shot” Bolt Hold-Open Feature

This safety feature, as shown in F, is activated when the last shot in the rifle has been fired (i.e. when the magazine and chamber are empty). The bolt will lock fully open. With the bolt in this position, you should visually check to be sure that the chamber and clip magazine are empty (See E).

NOTE: The “automatic” bolt hold-open will not function unless the empty magazine is still in the rifle.

Manual Bolt Hold-Open Feature

  1. This feature enables you to lock the action open with live rounds in the magazine or with the magazine out of the rifle.
  2. With the safety on “SAFE” and the rifle pointed in a safe direction, pull the bolt charging handle all the way back and hold it.
  3. Engage the lock by pushing the bolt control lever up and, while holding it up, release the bolt charging handle (See G).
  4. To close the bolt, push the bolt control lever down. (NOTE: If the magazine is loaded, this will chamber a round.) (See H)

What to do if your rifle fails to fire


If you have squeezed the trigger and nothing happens, remain in shooting position, pointing the gun in a safe direction. Count to 10,  then unload the rifle completely. (See “How to Unload”).

Underpowered Shot

A “squib” or underpowered shot, should not occur if the ammunition is clean, dry, and factory loaded. You can tell if a shot is underpowered by the unusually low sound it makes.

  • WARNING: Because the bullet may actually still be in the barrel, you must unload completely, (See “Manual” Bolt Hold-Open feature.) and determine, with a cleaning rod, if there is an obstruction. If there is, it should be removed by a qualified gunsmith. Otherwise,  personal injury or damage could result.


Your rifle has been sighted-in and testfired at the factory. Due to individual shooting characteristics, however, sighting should be range verified.

NOTE: Since the Model 7000 was designed for varmint hunters, who use telescopic sights almost exclusively, it was made with a receiver grooved for the appropriate rings. If you would like to have open sights installed, see a competent gunsmith.

Vertical Correction (Elevation)

To raise the point of impact, raise the rear sight, by moving the sight elevator rearward. To lower the point of impact, lower the rear sight, by moving the sight elevator forward.

Horizontal Correction (Windage)

To move the point of impact to the left, tap the rear sight base to the left. To move the point of impact to the right, tap the rear sight base to the right.

NOTE for the 70PSS: During assembly or disassembly of the rifle, if the takedown nut moves the rear sight elevator, it will change the point of impact.

Scope Mounting

Your rifle has a grooved receiver designed to handle tip-off-type 22 scope bases. They are made by Tasco, Weaver, and others, and are available through your local gun dealer. You may also order directly from Marlin Gun Service. Call 1-800-544-8892 for more information.

How to Clean Your Rifle

  • WARNING: Never attempt to wipe down or clean a loaded firearm. Follow instructions under “How to Unload” before cleaning.

CAUTION: Before using any solvent or other gun cleaning product, read the label carefully to be sure it will not damage either the finish, or any parts of this firearm.

NOTE for stainless steel models: Although stainless steel is corrosion resistant, it can rust. If the rifle gets wet, dirty, or is subject to excessive handling, wipe down metal parts with oil or a rust-inhibitor.

Minor scratches can be “buffed out” of stainless steel with a “Scotch-BriteTM Very Fine” pad, available in hardware and automotive supply stores.

Cleaning the bore

Since modern ammunition burns very cleanly, with normal use it is not necessary to clean the bore of your rifle. However, if it gets wet, or if any foreign material gets into the action or barrel, cleaning as described below is recommended.

With the safety on SAFE, remove the magazine and clear the action several times to be doubly sure no cartridges remain. Pull the charging handle back and lock the action open.

To clean the bore and barrel, use any standard .22 caliber commercial cleaning rod and cleaning patches. Clean the barrel with powder solvent and wipe lightly with gun oil after cleaning.

Cleaning the action

We recommend that you wear safety glasses while disassembling this rifle.

We recommend cleaning the inside of the receiver, bolt face, extractors, and breech end of the barrel (around the chamber) after firing each 250 rounds. (Frequency of cleaning may depend on brand of ammunition used.) A toothbrush and commercial gun cleaning solvent will simplify the job. (Be sure to follow manufacturer of gun cleaner’s directions, as some chemicals may damage the synthetic trigger guard.)

The steps listed below should be followed carefully to assure proper disassembly, cleaning and reassembly.

Step #1 — With the safety on SAFE, remove the magazine and clear the action several times to be sure the chamber is empty. Close the bolt (See H).

Step #2 — Unscrew takedown screws A and B as shown in I. (For the 70PSS, one end of the spanner wrench is a screw driver.) Remove the trigger guard assembly. Separate the rifle into two segments, the stock and the barreled action.

Release assembly post by squeezing and pushing in slotted end. Pull post free of action. (See J).


Remove action by sliding it to the rear and up (See K).


Step #3 — With the action removed, the bolt, charging handle, recoil spring and spring guide may now be removed.

  • WARNING: Recoil spring is compressed at this point and, if not handled properly, can fly from the receiver.

Pull the charging handle back slightly and, with the forefinger of your other hand, lift the muzzle end of the bolt from the receiver (See L).


As you begin to lift the bolt out, the charging handle will become free and can be removed. The recoil spring and spring guide are now within easy reach for removal (See M).


Step #4 — The barrel, receiver and action are now ready for thorough cleaning. The action should be cleaned in solvent, dried, and oiled sparingly prior to reassembly. Further disassembly of the action is not recommended and should only be attempted by a qualified gunsmith or the factory.

Step #5 — (Reassembly is easier if gun is secured in a padded vise, or held by an assistant.) To reassemble, place recoil spring guide into one end of the recoil spring, then place opposite end of spring into breech bolt. Next, put recoil spring guide into hole at the rear of the receiver. To prevent kinking the spring, hold breech bolt and recoil spring in one hand and use the other hand to support the spring as shown in N, while compressing spring until guide enters breech bolt.


Step #6 — The charging handle can now be positioned through the ejection port. To complete the insertion of the breech bolt,
be sure the charging handle fits into the slot provided for it in the bolt.

Reinstall the action by pulling the charging handle all the way back and locking it in the open position, and reversing the action
disassembly procedure (See O).


When reassembling the barreled action and stock, be sure the receiver is seated as far back in the stock as it will go while tightening the takedown screw. Otherwise, the rifle may not fire.

Reinstall the trigger guard assembly and tighten takedown screws.

When reassembling the barreled action to the stock, take care not to bend or damage the magazine release lever as you insert it through the slot in the trigger guard.

  • WARNING: Never attempt to wipe down or clean a loaded rifle.
For the 70PSS, if you intend to use your rifle after cleaning, replace the barrel as described in “How to Assemble the

Use a very thin coat of light oil during below freezing conditions. Condensation droplets will form soon after the rifle is brought into a warm room, or it may become wet during inclement weather. In any case, all moisture should be removed. Exterior metal finishes may be wiped down with a slightly oiled cloth. For long term storage, lightly oil the bore, barrel and action with gun oil. Your rifle should be completely unloaded and stored in a dry area. Never store your rifle in a carrying case.
