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).
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.
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.
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.
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:
Any commercially available 17 Mach 2 ammunition will function in your rifle.
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.
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”).
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.
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.
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.
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.
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.
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.
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.
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.
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.
|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.
