Ruger No. 1 Instruction Manual

							Firing a rifle with oil, grease, or any other material even
partially obstructing the bore may result in damage to the
rifle and serious injury to the shooter and those nearby.
Do not spray or apply lubricants directly on ammunition.
If the powder charge of a cartridge is affected by the lubri-
cant, it may not be ignited, but the energy from the
primer may be sufficient to push the bullet into the bore
where it may become lodged. Firing a subsequent bullet
onto the obstructed bore may damage the rifle and cause
serious injury or death to the shooter and those nearby.
Use lubricants properly. You are responsible for the proper
care and maintenance of your firearm.
IMPROPER LUBRICATION
DESTROYS GUNS

3. Use a clean, solvent-wetted patch to remove firing residue and dirt from all
“reachable” surfaces inside the receiver. Use the solvent-wetted toothbrush to
dislodge caked dirt from components and from surfaces inside the receiver
that can’t be reached with a patch. Use cleaning patches or the cloth to remove
the solvent.
4. Wipe all surfaces – internal and external – with a very light coat of oil. Oil and
similar preparations “collect” dirt particles which can interfere with reliable
functioning of the rifle. Therefore, use these preparations very sparingly. A
drop of oil applied to the breech block assembly components, the pivot points
of the trigger mechanism, the safety, the lever, and the latch, will work into all
the parts that need lubrication.
5. Reassemble the rifle and carefully wipe all solvent, lubricating and preservative
preparations from the stock.
!WARNING – LUBRICATION
OIL
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.
STORAGE
GUNS SHOULD NOT BE STORED LOADED!
USE THE LOCKING DEVICE SUPPLIED WITH THE RIFLE FOR STORAGE.
(SEEPAGE5)
Do notstore the rifle in a leather case. Leather, and many cloth cases, attract
moisture even though they may appear to be perfectly dry.
TO RENDER THE RIFLE INOPERATIVE FOR SAFE STORAGE
With the muzzle pointed in a safe direction, open the action and check the cham-
ber to be sur
e the rifle is completely unloaded!Remove the forend screw.
Carefully remove the forend and forend takedown nut. Open the lever and insert  
						

							a pin through the hole in the front of the hammer spring strut. With the muzzle
pointed in a safe direction, pull the trigger and then remove the hammer spring
assembly toward the front of the rifle. Now open the action and unscrew and
remove the lever pivot screw on the left side of the receiver. The hammer can be
removed from the bottom of the receiver. Replace the lever pivot screw, the
forend nut, the forend, and the forend screw.
Store the hammer spring assembly and the hammer in different locations. When
disassembled in this manner, the rifle is inoperable. It is impossible to fire the
rifle until the hammer spring assembly and hammer have been correctly
replaced into the rifle.
To reassemble the rifle for firing, remove the forend screw, the forend, and the
forend takedown nut. Unscrew and remove the lever pivot screw. Reinsert the
hammer into the receiver and secure it with the lever pivot screw. Replace the
hammer spring assembly with the down-turned rear end of the strut facing
downward. Replace the forend nut, remove the pin from the front of the hammer
spring assembly. Replace the forend and tighten the forend screw. Check to be
sure that the lever, hammer, trigger, and safety mechanisms work fully and
freely. The rifle is now reassembled and can be loaded and fired normally.
While the rifle is less likely to be used by unauthorized persons when disas-
sembled 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 ammuni-
tion.
22
Never place or store any firearm in
such a manner that it may be dis-
lodged. Firearms should always be
stored securely and unloaded, away
from children and careless adults. Use
the locking device originally supplied
with this firearm for storage.
The use of a locking device or safety
lock is only one aspect of responsible
firearms storage. For increased safety,
firearms should be stored unloaded
and locked in a location that is both
separate from their ammunition and
inaccessible to children and any other
unauthorized person.
STORE SECURELY & UNLOADED

QUICK DETACHABLE SLING SWIVEL
1. When attaching any QD swivel to its base, make sure the rotating gate is
FULLY ENGAGED on the pin and there is no gap between the rotating gate
and the swivel body. (See illustration below). A QD SWIVEL NOT ENGAGED
CAN ACCIDENTALLY BECOME DETACHED FROM ITS BASE.

To Attach Swivel To Base:
a. Press plunger.
b. Rotate gate.
c. Insert pin into base.
d. Rotate gate until pin enters hole in gate, then release plunger.
e. Make sure spring plunger fully engages pin, leaving no gap between gate and
swivel body.
f. To detach swivel, reverse the above procedure.
2. Each time you use your rifle with a sling, be sure the QD swivel is fully
engaged. Also, be sure to check the swivel periodically in the field to make cer-
tain it is fully engaged.
3. Brush, tree limbs or other obstructions can pull at the swivel, sling, carry
strap, scope or the firearm itself. If this happens, always check the swivel
IMMEDIATELY to be sure it is fully engaged. 
						

							24
4. NEVER CLIMB OVER A FENCE, JUMP A DITCH, SCALE STEEP HILLS OR
ROCKS, OR CLIMB A TREE OR TREE STAND WITH A LOADED FIREARM.
PRACTICE THE RULES OF FIREARM AND HUNTING SAFETY.
(See pp. 35 - 38)
Failure to follow these safety rules could result in a swivel accidentally becoming
detached from its base. If this happens, the firearm could fall, causing damage to
the firearm or scope, and even accidentally discharge resulting in injury or death
to yourself or others.
ATTACHING RUGER SCOPE RINGS
Each Ruger telescope ring is a mated assembly of a top and a base. Do not mix
the parts of the two ring assemblies as they are not interchangeable. On the
underside of each mounting ring assembly there is an integral lug, located off
center with respect to the front and back sides of the mount. The lug is nearer to
the front surface. By reference to the lug, the mounting ring can be correctly
assembled with the front of the ring toward the muzzle of the rifle.
1. Disassemble one ring and reassemble over the scope body between the turret
and the eyepiece. Remember - the lug on the base should be on the front side
of the scope.
2. Install the four top screws. Do not tighten.
3. Disassemble the other ring and install it on the forward section of the scope
tube with the lug forwardly also. Install the four top screws. Again, do not
tighten.
4. Assemble the rings to the receiver with the lugs engaging the recesses in the
top surface of the receiver. Tighten the clamp nuts so that the rings are locked
to the semicircular cuts on the sides of the receiver.
5. Rotate the scope until cross-hairs are aligned properly and slide scope to
desired eye relief. Then tighten the eight top screws each a bit at a time to grip
the scope body.
6. Sight in according to the directions with your scope.

SUGGESTED SIGHT PICTURE
Top of front sight even with top of
rear sight slide. Front sight cen-
tered in notch of rear sight slide.
Target bull’s-eye centered on top
of front sight.
SIGHT ADJUSTMENT
(For Standard Rifles Equipped With Open Sights)
The folding leaf rear sight is adjustable for elevation. The slide must be moved
one graduation to change the point of impact by approximately one inch at 25
yards. Shooting to determine the slide setting for ‘zero’ at a particular distance
should be done from a bench rest and over a measured distance. Use only a small
screwdriver with a blade tip that exactly fits the screw-head. Loosen the screws
only slightly so the slide doesn’t move too freely. Move the slide in the direction
you want the point of impact of the bullet to move. When the slide is positioned
at the desired height, carefully tighten both screws.
Lateral (windage) adjustment is made by “drifting’ the sight base in its slot. 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.

The Federal Gun Control Act, as well as the laws of most States and localities, do
not prohibit an individual (who is not otherwise barred from purchasing or pos-
sessing a firearm) from shipping a firearm directly to the manufacturer for
repair. However, before you ship your rifle to us, be certain that your State or
locality does not have a law or regulation which will prohibit you from receiving
the rifle from us after it has been repaired. If such receiving is prohibited, then
please have a Federally Licensed firearms dealer ship the gun to us. If your rifle
is sent to us by a dealer, it will be returned to him after being repaired. If a hand-
gun (pistol or revolver) is shipped by an individual who does not hold a Federal
Firearms License, it must be shipped via U.P.S. (Next Day Air). Persons who do
not hold a Federal Firearms License are prohibited by Federal law from shipping
a handgun by Mail. Handguns mailed in violation of the law are impounded by
the Post Office.

DESTROYED IN SHIPMENT.Please do not include rifle case, sling, telescopic
sights or custom accessories with a firearm being shipped to the factory for serv-
ice. Rifles and shotguns may be shipped via Parcel Post. Always insure your ship-
ment.
Enclose a letter which includes your name, address, telephone number, serial
number and model of the firearm. Describe in detail the trouble you have experi-
enced with your firearm, or the work you wish to have done. Merely stating that
the firearm “needs repair” is inadequate information.

shipping and handling charge. The charge for rebluing the Ruger No. 1 rifle is
$50.00 plus a $12.00 shipping and handling charge. Custom gunsmithing service
