State-By-State Warnings Certain states require by law that their own specified warning notices in larger-than-normal type be conspicuously included by the manufacturer, distributor, or retail dealer with firearms sold in that state. Sturm, Ruger sells its products in compliance with applicable laws and regulations. Because our products may be sold in these states, we include the following: California: ! WARNING ! ADVERTENCIA “A los niños los atraen las armas de fuego y las pueden hacer funcionar.
Maine: “ENDANGERING THE WELFARE OF A CHILD IS A CRIME. IF YOU LEAVE A FIREARM AND AMMUNITION WITHIN EASY ACCESS OF A CHILD, YOU MAY BE SUBJECT TO FINE, IMPRISONMENT OR BOTH. KEEP FIREARMS AND AMMUNITION SEPARATE. KEEP FIREARMS AND AMMUNITION LOCKED UP. USE TRIGGER LOCKS.” Maryland: “WARNING: Children can operate firearms which may cause death or serious injury.
New Jersey: “IT IS A CRIMINAL OFFENSE TO LEAVE A LOADED FIREARM WITHIN EASY ACCESS OF A MINOR.” New York City: “THE USE OF A LOCKING DEVICE OR SAFETY LOCK IS ONLY ONE ASPECT OF RESPONSIBLE WEAPONS STORAGE. ALL WEAPONS SHOULD BE STORED UNLOADED AND LOCKED IN A LOCATION THAT IS BOTH SEPARATE FROM THEIR AMMUNITION AND INACCESSIBLE TO CHILDREN AND ANY OTHER UNAUTHORIZED PERSONS.
! WARNING – LOCKING DEVICES DO NOT INSTALL INSIDE TRIGGER GUARD This firearm was originally sold with a key-operated locking device. While it can help provide secure storage for your unloaded firearm, any locking device can fail. All guns are designed to fire if they are loaded and the trigger is pulled. Therefore, never install the locking device inside the trigger guard or in any way that it can possibly pull the trigger! Do not leave the keys in the lock.
FIREARMS SAFETY-YOUR RESPONSIBILITY SAFETY MUST BE THE FIRST AND CONSTANT CONSIDERATION OF EVERY PERSON WHO HANDLES FIREARMS AND AMMUNITION. This Instruction Manual is designed to assist you in learning how to use and care for your RUGER® M-77® MARK II rifle properly. Only when you are certain you fully understand the Manual and can properly carry out its instructions should you practice loading, etc. with live ammunition.

All mechanical components are made of heat-treated chrome-molybdenum or stainless steel with music wire coil springs throughout the mechanism (except the magazine spring). The rifle is available in short, standard, and magnum action lengths, and in right-hand and left-hand versions. The RUGER® M-77® MARK II Magnum Rifles are the first true “magnum length” actions offered by Sturm, Ruger.
SPECIAL SAFETY NOTE M77 MK II TARGET RIFLE ONLY The special model you have selected is specifically designed for long-range precision target shooting. As such, it demands that you take extra safety precautions. The special trigger in the Target version of the RUGER® M-77® MARK II has a two-stage pull, both for safety and precise placement of shots. Initial movement of the trigger is relatively “slack” until resistance is felt after approximately 1/8” of travel.
“Safe” position, the bolt handle is locked in the closed (full down) position, in order to prevent inadvertent lifting of the bolt handle and to ensure that the rifle will be ready to fire when the safety is moved to the “fire” position. Practice (with an unloaded rifle) moving the safety selector to the three positions until you know the position of the safety selector for the three modes– “Fire,” “Load-Unload,” and “Safe.
The safety selector is held in each of its three positions by a plunger that is under spring tension. Therefore, the gun user should frequently check the position of the safety selector to be certain it has not been inadvertently moved.
! WARNING – AMMUNITION Death, serious injury, and damage can result from the use of wrong ammunition, bore obstructions, powder overloads, or incorrect cartridge components. Even the strongest gun can be blown up by excess pressure. Only use correct ammunition loaded to U.S. Industry Standards. Always wear shooting glasses and hearing protectors.
Loading the magazine: (Safety should be in “Load-Unload” position). With the bolt open, load cartridges of the correct caliber directly into the magazine by pressing one cartridge at a time into the magazine. Loading the chamber: (Safety should be in “Load-Unload” position). Do not chamber a cartridge until you are ready to shoot immediately. After loading the magazine, push the bolt handle forward. This will strip a cartridge from the magazine and push the cartridge ahead of the bolt into the chamber.
To fire the rifle: When a cartridge is chambered and the rifle is pointed in a safe direction, put the safety in the “Fire” position. Pulling (squeezing) the trigger will discharge the cartridge. Always be certain that you know where the bullet will strike when you fire the rifle. Never allow the thumb to touch the cocking piece when firing as it can be pinched when the cocking piece moves forward to fire the rifle.
CORRECT UNLOADING SEQUENCE SAFETY IN "LOAD-UNLOAD" POSITION 2 1 3 4 ! WARNING – UNLOADING Removing cartridges from the magazine does not prevent the rifle from being fired! When there is a cartridge in the chamber and the safety selector is in the “Fire” position, the cartridge will discharge if the trigger is pulled. It is absolutely essential for the user to know how to completely unload it. “Completely” means emptying the magazine and removing a chambered cartridge.
–When attempting to extract a cartridge that is “stuck” in the chamber do not use any type of tool that is likely to act as a “firing pin” and discharge the cartridge should the tool impact on the primer. –After clearing a jam, inspect the gun mechanism to determine if dirt might be the cause of the problem. Excess lubricant or grease can cause cartridges to feed sluggishly or fail to extract.
TO MINIMIZE MALFUNCTIONS (“JAMS”) Firearms of all makes and types are susceptible to occasional malfunctioning due to a cartridge not feeding from the magazine to the chamber, or due to a cartridge or fired case not being extracted and ejected. To minimize the possibility of such occurrences the gun user should: –Use ammunition of the correct caliber and type which is loaded to U.S. Industry Specifications. Do not use cartridges that are deformed, or cartridges that have been reloaded.
Before attempting to disassemble the rifle for the first time, study the parts drawing and parts list so as to be familiar with the relative position, appearance and name of each part. Carry out the disassembly slowly and carefully note the position of the part in the gun before starting to remove it. If a part is under spring tension (such as, the Safety Selector, Bolt Stop, Trigger) remove it cautiously and anticipate the direction the spring and plunger are most likely to “jump.
7. To remove the sear: a. Press out the sear pivot pin. b. Turn receiver upside down and slide sear forward. Sear will drop out of the top slot in the receiver. 8. To remove safety assembly: a. Rotate the safety selector so that the upper section is positioned fully over the center of the receiver tang. b. While holding the safety selector in place with thumb and forefinger, slide the retainer up out of receiver.
5. To reassemble firing pin assembly into bolt: Screw the assembly fully into the bolt. The assembly is properly positioned in the bolt when the flat on the bottom right side of the bolt sleeve (front of bolt facing you) is aligned with the flat on the bottom end of the bolt handle. Note: There is a shallow notch on the rear end of the bolt body – at the end of the cam cut – into which the nose of the cocking piece ‘fits.
CARE AND CLEANING ! WARNING: BEFORE CLEANING, BE CERTAIN THE RIFLE AND ITS MAGAZINE CONTAIN NO CARTRIDGES. A firearm must be free of rust, dirt, grease and firing residues to function safely and reliably. Periodic maintenance, which includes inspection of components to determine if they are in proper working order, is absolutely essential. Firing deposits particles of bullet lubricant and powder in the bore, chamber, bolt, receiver, magazine and other parts of the rifle.
6. If the rifle is to be stored for an extended period, clean the rifle thoroughly. Disassemble to the extent described elsewhere in this manual, taking care to put pins and similar easily mislaid and “rolling” components in a tray. Rewipe all surfaces with preservative oil. Reassemble and store properly.
While the rifle is less likely to be used by unauthorized persons when disassembled in the above manner, it is always safest to store a firearm with the supplied locking device correctly installed, or to store the firearm in a gun safe or other secure location, away from children and unauthorized adults. Guns should always be stored securely, unloaded and separate from their ammunition. ! WARNING – STORAGE Never place or store any firearm in such a manner that it may be dislodged.
External surfaces most subject to rusting from handling, or from exposure to the elements should be cleaned and wiped dry after use or after exposure to adverse conditions. If the rifle is to be stored, coat it with a light film of oil or preservative. Where the rifle is in continuing use, and the presence of oil or grease would be objectionable, then the external surfaces can be coated (after cleaning and drying) with a paste wax formulated for use on metals.
the sight can be moved. Place a short brass rod against the sight base (and only the base) and tap the sight in the direction you wish to move the point of impact, then tighten the slotted screw. NOTE: The ‘rule’ of rear sight adjustment is: Move the sight in the direction that you want the point of impact of the bullet to move. As examples, to raise the point of bullet impact, raise the elevation slide (blade). To move the point of bullet impact to the right, move the sight to the right.

THE BASIC RULES OF SAFE FIREARMS HANDLING We believe that Americans have a right to purchase and use firearms for lawful purposes. The private ownership of firearms in America is traditional, but that ownership imposes the responsibility on the gun owner to use his firearms in a way which will ensure his own safety and that of others. When firearms are used in a safe and responsible manner, they are a great source of pleasure and satisfaction, and represent a fundamental part of our personal liberty.
A safe direction must take into account the fact that a bullet may penetrate a wall, ceiling, floor, window, etc., and strike a person or damage property. Make it a habit to know exactly where the muzzle of your gun is pointing whenever you handle it, and be sure that you are always in control of the direction in which the muzzle is pointing, even if you fall or stumble. Keep your finger off the trigger until you are ready to shoot. 3. FIREARMS SHOULD BE UNLOADED WHEN NOT IN USE.
5. BE SURE OF YOUR TARGET BEFORE YOU SHOOT. Don’t shoot unless you know exactly where your bullet is going to strike. Be sure of the bullet stop behind your target, even when dry-firing with an unloaded gun. If you are in the field hunting, do not fire at a movement or noise. Take the time to be absolutely certain of your target before you pull the trigger. 6. WEAR SHOOTING GLASSES AND HEARING PROTECTORS WHEN YOU SHOOT.
8. DON’T SHOOT AT A HARD SURFACE, OR AT WATER. Bullets can glance off many surfaces like rocks or the surface of water and travel in unpredictable directions with considerable velocity. 9. NEVER TRANSPORT A LOADED FIREARM. Firearms should always be unloaded before being placed in a vehicle. A suitable carrying case or scabbard should be used to carry an unloaded firearm to and from the shooting area. 10. AVOID ALCOHOLIC BEVERAGES WHEN SHOOTING. Don’t drink until the day’s shooting is over.
A BRIEF ACCOUNT OF AN EXTRAORDINARY ACHIEVEMENT: RUGER FIREARMS One of the few American firearms manufacturers whose management has remained in the same family since starting in business, Sturm, Ruger & Company, Inc., had its beginning in a small machine shop occupying a rented frame building in Southport, Connecticut. In January, 1949, with an initial investment of only $50,000 and an idea, William B. Ruger and Alexander M. Sturm started production of a .
WHY NO WARRANTY CARD HAS BEEN PACKED WITH THIS NEW RUGER FIREARM The Magnuson-Moss Act (Public Law 93-637) does not require any seller or manufacturer of a consumer product to give a written warranty.
