Ruger Mini 30 Rifle Instruction Manual

A cartridge can be “discharged” before it is cham-
bered if its primer receives a sharp blow. If a car-
tridge hangs up, jams, or binds when being cham-
bered or when being fed from the magazine into
the chamber, do not attempt to force it into the
chamber by pushing or striking the bolt.Any jam
or feeding problem is a signal to immediately stop
using the gun until it can be determined what is
wrong. Most failures of a cartridge to feed or to
chamber are caused by a damaged magazine,
improper gun...

DISASSEMBLY
Be Sure Rifle Is Unloaded!
Although The Mini Thirty Rifle can be disassembled, reassembled, and cleaned
in almost any surrounding, it is preferrable to carry out these procedures on a
workbench or table which has a covered top. A piece of shallow nap rug or an
old blanket is an ideal covering. Such a covering keeps the rifle from slipping
and...

punch, screwdriver shank, or
other suitable instrument insert-
ed into the hole in the rear of the
trigger guard as a lever to spring
open the trigger guar
dfrom its
latched position        (See Fig. 8).
WARNING: Do not use a cartridge to unlatch the trigger guard because of the dan-
ger of loosening the bullet in the cartridge case (See Warnings in “Ammunition”
section, p. 11).

NOTE:The Mini Thirty Rifle is like the M1 Garand and many other types of
autoloading rifles in that the hammer can fall if the trigger is pulled when
the bolt is partially retracted. It is important for the shooter to realize that
the firing pin cannot contact the cartridge until the bolt is safely locked,
regardless of the position of the slide.

Removal of the gas block assembly is not necessary and is not advisable.The gas
block assembly is factory fitted using special fixtures and torque tools. Attempting
to fit the gas block assembly without the required special equipment can result in
damage to the components and malfunctioning of the rifle.

REASSEMBLY...

3.Final reassembly of rifle:
a. Replace stock by inserting its front end into the gas block at a slight angle.
When the stock is correctly seated into the gas block, the stock can be
swung down into full contact with the receiver.
b. Insert the opened trigger housing assembly, safety “ON”, into the stock (the
hammer must be cocked prior to insertion). When fully seated, swing the
trigger guard fully into place until it locks shut. An audible “click” will be
heard when it is correctly locked. Cycle the...

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 ammuni-
tion. If the powder of a cartridge is affected by
the lubricant, it may not be ignited, but the
primer firing may push the bullet into the bore
where it may be lodged. Firing a subsequent
bullet into the obstructed bore may damage the
rifle and cause serious injury or death to...

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...

MAINTENANCE OF STAINLESS STEEL RIFLES
Firearms and components made of stainless steel are relatively more resistant to
corrosion than those of blued steel. However, in the interest of proper operation
and long life of a stainless steel firearm, inspect it frequently and clean, lubricate
and apply an appropriate rust preventative.
Sometimes discoloration occurs from perspiration or from contact with some
types of gun cases. Rusting may occur as a result of the firearm being exposed to
moisture, salt air...
