Ruger Mini 30 Rifle Instruction Manual

1. Fold rear sight down. 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 screw each a bit at a time to grip
the scope body.
6. Sight in according to the directions with your scope. 
SIGHT ADJUSTMENT
Shooting to determine the setting of the elevation slide (aperture) should be
done from a bench rest and over a measured distance.
The rear sight is adjustable for both windage and elevation. Lateral (windage)
adjustment is made by loosening the Rear Sight Windage Lock Screw (with the
hex-head wrench provided with the rifle) until the sight base requires finger pres-
sure to be moved. (See illustration below). Move the sight in the direction you
wish to move the point of impact. Before moving the sight, pencil mark an index
line on the sight base and on the receiver so that the amount of sight movement
can be detected. After desired positioning of the sight base has been achieved,
tighten the lock screw firmly.

WINDAGE ADJUSTMENT:To move the bullet impact point to the left, move
the rear sight base to the left. To move the bullet impact point to the right
,

e to retighten lock screw after
adjustment.

SUGGESTED SIGHT PIC-
TURE
The front sight is aligned in the
center of the rear sight aperture
(“peep”) and the target (bullseye) is
positioned to appear as if it is sit-
ting on top of the front sight.
ELEVATION ADJUSTMENT:To move the bullet impact point upor down, move
the elevation slide (the “peep”) by loosening both its screws (using a small
screwdriver with a blade tip that exactlyfits the screw-head) 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 retighten both screws.

Guns should be sent prepaid. We will not accept collect shipments.
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.
DO NOT SEND GUN BOXES OR LITERATURE THAT YOU CONSIDER TO BE
COLLECTOR’S ITEMS – THESE ARE INVARIABLY DAMAGED OR
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.
Work performed will bear a net minimum labor charge of $20.00 plus a $12.00
shipping and handling charge. The charge for rebluing the RUGER
®MINI
THIRTY RIFLEis $50.00 plus a $12.00 shipping and handling charge.
Custom gunsmithing service or nonstandard alterations are NOT AVAILABLE

Company policy is to proof-test and/or function fire all barrels after fitting to the
receivers in which they are to be used. This procedure ensures maximum protec-
tion to our customers. The special proof-test ammunition used in this testing is
sold only to bonafide firearms manufacturers and is not available to gun shops,
gunsmiths, or individuals.
Because the receiver of the RUGER
®MINI THIRTY RIFLE is a serial
numbered component, it is defined as a “firearm” by Federal law and is not sold
as a separate component.
