|
The Ruger Mark II Pistol
|
|||
|
|
|||
|
APPLICABILITY
|
|||
|
The following applies to all models of the Ruger Mark II .22
|
|||
|
caliber pistol, including the Government Model, as manufactured by
|
|||
|
Sturm, Ruger & Company, Inc. (hereinafter referred to as "Ruger").
|
|||
|
|
|||
|
INITIAL INSPECTION
|
|||
|
Upon initial receipt of the pistol, it should be inspected and
|
|||
|
cleaned to assure complete, undamaged delivery and reliable, safe
|
|||
|
functioning.
|
|||
|
|
|||
|
DESCRIPTION
|
|||
|
The Ruger Mark II automatic pistol is a .22 caliber rimfire,
|
|||
|
10 shot magazine fed, semiautomatic, recoil (also called
|
|||
|
"blowback") operated weapon, chambered for the .22 caliber Long
|
|||
|
Rifle (LR) cartridge. This model includes the following features
|
|||
|
with which the user should be thoroughly familiar.
|
|||
|
|
|||
|
BOLT
|
|||
|
The bolt can be manually retracted to chamber a cartridge from
|
|||
|
a loaded magazine or to clear the pistol by pulling the bolt ears
|
|||
|
to their rearmost position. Releasing the bolt ears will cause the
|
|||
|
bolt to fly forward under spring pressure.
|
|||
|
|
|||
|
BOLT STOP ASSEMBLY
|
|||
|
The bolt stop assembly holds the bolt in a rearward position.
|
|||
|
It may be actuated either manually or automatically. Whenever there
|
|||
|
is an empty magazine assembly in the pistol, and the bolt moves to
|
|||
|
its rearmost position, the magazine follower button automatically
|
|||
|
actuates the bolt stop to hold the bolt rearward. This will occur
|
|||
|
regardless of whether the bolt is moved rearward when the last
|
|||
|
round is fired or by manual retraction. If there is a loaded
|
|||
|
magazine in the pistol or if there is no magazine in the pistol,
|
|||
|
the user may actuate the bolt stop by manually retracting the bolt
|
|||
|
and pushing up on the bolt stop thumbpiece. To release the bolt
|
|||
|
from the bolt stop when there is a loaded magazine or no magazine
|
|||
|
in the pistol, merely pull the bolt ears to the rearmost position
|
|||
|
and release. If there is an empty magazine in the pistol, the bolt
|
|||
|
can be released by pulling the bolt ears rearward and manually
|
|||
|
depressing the bolt stop thumbpiece to allow the bolt to return to
|
|||
|
its forward position.
|
|||
|
|
|||
|
- LOADED MAGAZINE WARNING -
|
|||
|
|
|||
|
The bolt stop is spring loaded to move downward. Therefore, when
|
|||
|
there is a loaded magazine in the pistol and the pistol is jarred
|
|||
|
to the extent that the bolt moves rearward, the bolt will fly
|
|||
|
forward and chamber a cartridge. For this reason the safety of the
|
|||
|
pistol should always be in the on ("S") safe position except when
|
|||
|
the user is positioned to fire the pistol at a selected target.
|
|||
|
|
|||
|
SAFETY
|
|||
|
When the safety assembly is in its uppermost ("S") safe
|
|||
|
position, the sear is locked and the pistol will not fire. When the
|
|||
|
safety is in its lower ("F") fire position, the pistol will fire!
|
|||
|
The safety can only be moved to its safe ("S") position when the
|
|||
|
hammer is cocked. Therefore, the safety serves as a cocking
|
|||
|
indicator. The bolt can be manually retracted and released when the
|
|||
|
safety is on ("S"). This feature allows the pistol to be loaded or
|
|||
|
unloaded and allows a cartridge to be chambered when the safety is
|
|||
|
on ("S"). The safety should be on ("S") at all times except when
|
|||
|
the user is deliberately positioned to fire at a selected target.
|
|||
|
|
|||
|
TARGET MODEL TRIGGER SCREW
|
|||
|
The trigger assembly contains an overtravel screw on the
|
|||
|
target models. This screw is adjusted at the Ruger factory for
|
|||
|
proper functioning and should not need adjustment. The purpose of
|
|||
|
the overtravel screw is to limit the distance the trigger moves
|
|||
|
after the hammer falls. Improper adjustment of this screw results
|
|||
|
in either (a) the screw being screwed out so far that the hammer
|
|||
|
will not fall or (b) the screw will not be screwed in far enough
|
|||
|
and thereby allowing excess overtravel to the detriment of
|
|||
|
accuracy. Adjustment of this trigger overtravel screw, if required,
|
|||
|
should only be performed by a qualified armorer.
|
|||
|
|
|||
|
MAGAZINE
|
|||
|
The 10 shot magazine assembly is readily identified by the
|
|||
|
removable plastic base decorated with a silver "eagle" and is
|
|||
|
designated by Ruger as the M10 magazine. This is the only Ruger
|
|||
|
factory magazine that should be used with the Mark II pistol
|
|||
|
because it is the only Ruger magazine which will correctly function
|
|||
|
the bolt stop. Use of non-factory magazines is not recommended by
|
|||
|
Ruger. However, the experience at Combat Arms has been that the 12
|
|||
|
round magazine from Ram-Line, Inc. (part number MAK 1210) has shown
|
|||
|
that this magazine is the ONLY non-factory magazine that
|
|||
|
consistently works in the Ruger MK II pistol. The Ram-Line, Inc.
|
|||
|
MAK 1210 magazine also has a life time warranty! It costs $12.95
|
|||
|
(as of this writing) and is a stock item at Combat Arms. However,
|
|||
|
use of a magazine made by other than Ruger may void Ruger's
|
|||
|
warranty.
|
|||
|
|
|||
|
|
|||
|
- MAGAZINE USE WARNING -
|
|||
|
|
|||
|
Do not use the Ruger 9 shot magazines (identified by their
|
|||
|
non-removable bases) designed for earlier model Ruger pistols (Mark
|
|||
|
I, etc.) in Mark II pistols. Do not use Ruger 10 round M10
|
|||
|
magazines in Ruger pistols other than the Mark II.
|
|||
|
|
|||
|
|
|||
|
- MAGAZINE FOLLOWER USE CAUTION -
|
|||
|
|
|||
|
Never lower the magazine follower button on the magazine and then
|
|||
|
permit it to snap upward. Always "ride" the button up and down with
|
|||
|
your thumb to avoid damage to the magazine and possible discharge
|
|||
|
of .22 caliber rimfire cartridges in the magazine.
|
|||
|
|
|||
|
- WARNING -
|
|||
|
|
|||
|
The Mark II pistol will fire when a live round is chambered,
|
|||
|
regardless of whether or not a magazine is installed in the pistol.
|
|||
|
Removing the magazine does not unload the pistol. To unload the
|
|||
|
pistol, FIRST REMOVE THE MAGAZINE, THEN PULL THE BOLT FULLY TO THE
|
|||
|
REAR AND EJECT THE CARTRIDGE. DO NOT ASSUME THAT THE CHAMBER IS
|
|||
|
EMPTY; ALWAYS VISUALLY INSPECT THE CHAMBER EVERY TIME YOU HANDLE
|
|||
|
THE PISTOL. THE SAFETY SHOULD ALWAYS BE ON ("S") WHEN UNLOADING THE
|
|||
|
PISTOL.
|
|||
|
|
|||
|
Ammunition
|
|||
|
The Ruger Mark II automatic pistol is chambered for the
|
|||
|
caliber .22 Long Rifle cartridge, standard or high velocity. Use
|
|||
|
only ammunition manufactured to U.S. industry standards or to U.S.
|
|||
|
military specifications. Do not attempt to load .22 Long, .22 Short
|
|||
|
or any other type of .22 caliber ammunition into the magazine or
|
|||
|
the chamber of the Ruger Mark II pistol.
|
|||
|
|
|||
|
|
|||
|
- AMMUNITION WARNING -
|
|||
|
|
|||
|
The Ruger Mark II pistol may be damaged and death or serious injury
|
|||
|
may occur to the user or other persons from any condition which
|
|||
|
contributes to the generation of excessive pressure or the
|
|||
|
uncontrolled release of gas within the Mark II pistol. These
|
|||
|
conditions can be caused by barrel or chamber obstructions,
|
|||
|
propellant powder overloads or by defective, incorrect or
|
|||
|
improperly loaded and assembled cartridge components. The
|
|||
|
relatively thin, soft metal used in .22 caliber rimfire cartridges
|
|||
|
makes burst cartridge case heads a common occurrence in firearms
|
|||
|
of this caliber. Therefore shooting glasses should ALWAYS be worn
|
|||
|
when firing the Mark II pistol.
|
|||
|
|
|||
|
|
|||
|
- BARREL OBSTRUCTION WARNING -
|
|||
|
|
|||
|
Before loading or firing the pistol, examine the barrel to be
|
|||
|
certain that it is clear and unobstructed. Firing the Mark II
|
|||
|
pistol with any obstruction in the barrel - even a heavy coating
|
|||
|
of oil or even drops of water - may result in damage to the pistol
|
|||
|
and injury to the user or persons nearby. A misfire or unusual
|
|||
|
report on firing is always a signal to cease firing immediately
|
|||
|
and examine the chamber and bore. If there is any type of
|
|||
|
obstruction - even a partial obstruction - the user must clear the
|
|||
|
obstruction with a cleaning rod and bore brush before firing the
|
|||
|
Mark II pistol.

Disassembling the Ruger Mark II
|
|||
|
|
|||
|
- LOADED WEAPON WARNING -
|
|||
|
|
|||
|
Never clean, lubricate, disassemble, assemble or work on the Mark
|
|||
|
II pistol while it is loaded. Keep all loaded ammunition away from
|
|||
|
the cleaning area.
|
|||
|
|
|||
|
|
|||
|
- MUZZLE SAFETY WARNING -
|
|||
|
|
|||
|
Keep the muzzle of the Ruger Mark II pistol pointed in a safe
|
|||
|
direction at all times during the disassembly and assembly of this
|
|||
|
pistol.
|
|||
|
|
|||
|
|
|||
|
REMOVAL OF THE MAGAZINE
|
|||
|
Place the safety on ("S"). With the thumb of either hand, push
|
|||
|
the knurled magazine catch rearward and pull the magazine assembly
|
|||
|
down out of the lower receiver by its grooved base. Remove all
|
|||
|
cartridges from the magazine by pushing them forward and allowing
|
|||
|
them to pop out.
|
|||
|
|
|||
|
CHECK CHAMBER FOR NO CARTRIDGES
|
|||
|
With the pistol pointed in a safe direction and YOUR FINGER
|
|||
|
OFF THE TRIGGER, grasp the bolt ears with the thumb and index
|
|||
|
finger and pull the bolt fully rearward. Make certain the Ruger
|
|||
|
Mark II is empty! Visually verify that no ammunition is in the
|
|||
|
chamber. Release the bolt ears and allow the bolt to fly forward.
|
|||
|
|
|||
|
UNCOCK THE HAMMER
|
|||
|
The safety must be off ("F") and the pistol uncocked to
|
|||
|
disassemble the Mark II. Point the weapon in a safe direction and,
|
|||
|
with the pistol unloaded, pull the trigger. The hammer must be
|
|||
|
uncocked to relieve the pressure on the mainspring before the
|
|||
|
weapon can be disassembled.
|
|||
|
|
|||
|
UNLATCHING THE MAINSPRING HOUSING
|
|||
|
The perfect "tool" to use for raising the mainspring housing
|
|||
|
latch is a lady's bobby pin. Combat Arms has found nothing better
|
|||
|
for disassembling the Ruger Mark II than this. Using your
|
|||
|
fingernails will just result in broken nails. If you use a
|
|||
|
screwdriver, you risk scratching the pistol. Some users have
|
|||
|
reported that they use a piece of string looped over the latch.
|
|||
|
Using the bobby pin, lift the mainspring housing latch UP out of
|
|||
|
the handgrip as far as it will go, much like opening the blade of
|
|||
|
a pocket knife. This will bring the latch to an approximate 90<39>
|
|||
|
angle to the handgrip.
|
|||
|
|
|||
|
INITIALLY POSITIONING THE HAMMER STRUT
|
|||
|
Point the empty pistol straight up and pull the trigger in
|
|||
|
order to make the hammer fall to its rearmost position.
|
|||
|
|
|||
|
REMOVE THE MAINSPRING HOUSING ASSEMBLY
|
|||
|
Pull straight DOWN on the mainspring housing until the
|
|||
|
mainspring housing pin clears its hole in the top of the receiver.
|
|||
|
With new pistols it may be necessary to lightly tap (with a
|
|||
|
plastic, rubber or wooden hammer) on the end of the mainspring
|
|||
|
housing pin which protrudes through the top of the upper receiver
|
|||
|
assembly while pulling downward on the mainspring housing. The
|
|||
|
mainspring housing is now able to be removed from the pistol.
|
|||
|
|
|||
|
POSITIONING THE HAMMER FORWARD
|
|||
|
Point the Mark II muzzle DOWN and pull the trigger.
|
|||
|
|
|||
|
REPOSITIONING THE HAMMER STRUT
|
|||
|
Now raise the empty pistol vertically and point it straight
|
|||
|
up until you hear a click. This click tells you that the hammer
|
|||
|
strut has fallen back. If you do not hear the click, go back to the
|
|||
|
previous step, entitled POSITIONING THE HAMMER FORWARD.
|
|||
|
|
|||
|
REMOVAL OF THE BOLT ASSEMBLY
|
|||
|
You can now pull the bolt out of the receiver by pulling on
|
|||
|
the bolt ears while continuing to point the pistol at the ceiling.
|
|||
|
If the bolt will not come out, then the hammer is not positioned
|
|||
|
aft; go back two steps to POSITIONING THE HAMMER FORWARD.
|
|||
|
|
|||
|
REMOVAL OF THE UPPER RECEIVER ASSEMBLY
|
|||
|
Grasp the lower receiver and hold the bolt stop thumbpiece UP.
|
|||
|
Hold the pistol over a padded work surface which will receive the
|
|||
|
upper receiver when it is removed. Tap the rear of the upper
|
|||
|
receiver with a plastic, rubber or wooden hammer to disengage the
|
|||
|
upper receiver from the lower receiver.
|
|||
|
|
|||
|
DISASSEMBLY OF THE BOLT
|
|||
|
Lift the recoil spring assembly UP out of its slot in the bolt
|
|||
|
assembly. NOTE: no further disassembly of the bolt should be needed
|
|||
|
for routine cleaning. For further disassembly, push out the firing
|
|||
|
pin stop. This will allow the firing pin, firing pin spring and the
|
|||
|
firing pin spring support to drop free. With a pointed object, such
|
|||
|
as a punch of the proper size, push the extractor plunger rearward
|
|||
|
until the extractor can be lifted out of the side of the bolt.
|
|||
|
Slowly release the extractor plunger, allowing the plunger and
|
|||
|
extractor spring to fall free of the bolt.
|
|||
|
|
|||
|
DISASSEMBLY OF THE MAGAZINE
|
|||
|
Hold the Ruger M10 magazine assembly upside down, keeping the
|
|||
|
base of the magazine pointed away from people or objects. Insert
|
|||
|
a 1/16" drift punch through the hole in the base and depress the
|
|||
|
magazine base plunger approximately <1B>". Slide the base forward
|
|||
|
very slowly, being very careful to keep the plunger and mainspring
|
|||
|
under control at all times. If not contained, these parts will fly
|
|||
|
out with considerable force. With the base fully removed, slowly
|
|||
|
relax the pressure on the plunger and spring and remove them. Hold
|
|||
|
the magazine flat with the magazine follower button up. Align the
|
|||
|
magazine follower button with the circular opening near the lower
|
|||
|
end of the magazine tube. Lift out the button. The magazine
|
|||
|
follower can now be removed.
|
|||
|
|
|||
|
CLEAN THE PISTOL
|
|||
|
Gather together the proper sized cleaning rod with a .22
|
|||
|
caliber brass or bronze bristle bore brush and a slotted tip into
|
|||
|
which a cleaning patch can be inserted. Also needed are clean cloth
|
|||
|
patches and clean soft cloths. Do not use stainless steel brushes
|
|||
|
on the weapon unless the Mark II is constructed of stainless steel.
|
|||
|
Stainless steel brushes will remove the bluing on blued pistols.
|
|||
|
A bronze or brass "toothbrush" is especially helpful for scrubbing
|
|||
|
parts. Do not use the bore brush for scrubbing anything except the
|
|||
|
barrel and magazine housing.
|
|||
|
|
|||
|
Combat Arms and the United States military recommend that you
|
|||
|
use Break-Free (CLP)(tm). Under no circumstances should you ever
|
|||
|
use WD-40(tm) on any weapon! If you need a solvent, Combat Arms
|
|||
|
recommends that you use Shooter's Choice(tm) followed by CLP. The
|
|||
|
Ruger Mark II should be cleaned at least every 400 rounds and after
|
|||
|
each firing period.
|
|||
|
|
|||
|
Using a cleaning rod with a slotted tip, run a CLP wetted
|
|||
|
patch through the full length of the barrel from the chamber end
|
|||
|
several times to remove loose material. Then attach a bronze or
|
|||
|
brass bristle bore brush to the cleaning rod and wet it in CLP.
|
|||
|
Run the bore brush back and forth through the full length of the
|
|||
|
barrel at least a dozen times. Make sure that the rod is pushed all
|
|||
|
the way through the barrel until the entire bore brush clears the
|
|||
|
muzzle end. Do not reverse the direction of the brush until it has
|
|||
|
completely exited from the muzzle end of the barrel or the bore
|
|||
|
brush may bind up inside the barrel.
|
|||
|
|
|||
|
Using the toothbrush soaked in CLP, scrub the area around the
|
|||
|
chamber until it is clean. Remove the bore brush from the cleaning
|
|||
|
rod and attach the slotted tip again. Run several dry patches
|
|||
|
through the barrel until they come out clean. If necessary, attach
|
|||
|
the bore brush to the cleaning rod again and scrub the barrel with
|
|||
|
a CLP soaked bore brush. Continue the process until the barrel is
|
|||
|
clean.
|
|||
|
|
|||
|
Failing to do this consistently and properly will cause
|
|||
|
fouling of the barrel with a natural loss of accuracy. Grease
|
|||
|
accumulation in the chamber area can interfere with the proper
|
|||
|
feeding of cartridges from the magazine.
|
|||
|
|
|||
|
Using a loose clean patch soaked with CLP, remove all powder
|
|||
|
residue from all components of the mechanism. If grease or dirt
|
|||
|
cannot be removed by merely wiping with the patch, then use your
|
|||
|
brass toothbrush soaked with CLP. After using the brass toothbrush,
|
|||
|
wipe all of the scrubbed areas with a clean CLP wetted patch. After
|
|||
|
cleaning the bore, run a clean dry patch through the barrel and
|
|||
|
then follow it with a patch that has a light coat of CLP on it.
|
|||
|
This will put a light coat of CLP on the inside of the barrel and
|
|||
|
protect it from corrosion.
|
|||
|
|
|||
|
Wipe all surfaces with a clean cloth that has a light coat of
|
|||
|
CLP on it. If the lower receiver and its mechanism is especially
|
|||
|
dirty, flood it with CLP, leave it sit soaking for 2 hours and then
|
|||
|
flush it out with more CLP. Remove the grip panels before soaking
|
|||
|
or flushing the pistol and make certain that all foreign matter is
|
|||
|
removed after cleaning. Lightly lubricate the lower receiver with
|
|||
|
CLP after cleaning.
|
|||
|
|
|||
|
When cleaning the bolt face, breech areas, etc. with the
|
|||
|
toothbrush, work carefully so as not to damage components.
|
|||
|
|
|||
|
Reassemble the pistol as detailed later in this manual. If the
|
|||
|
Ruger Mark II pistol is to be stored for an extended period, the
|
|||
|
final wiping should be done with a heavier coat of CLP.
|
|||
|
|
|||
|
Clean the internal and external parts of the disassembled
|
|||
|
magazine with CLP. The inside of the magazine can be scrubbed with
|
|||
|
a bore brush soaked in CLP. After scrubbing, remove all loose
|
|||
|
material with several clean patches, just like you did with the
|
|||
|
cleaning of the barrel. Leave a very light coat of CLP on the
|

|
inside of the magazine and on the magazine spring.
|

|
|||
|
- MAGAZINE CLEANING CAUTION -
|
|||
|
|
|||
|
Be careful not to scratch the interior and exterior of the Ruger
|
|||
|
M10 magazine, particularly along the front section where the bullet
|
|||
|
tips ride. Be very careful not to bend the magazine lips.
|
|||
|
|
|||
|
Only a very small amount of CLP is needed to provide adequate
|
|||
|
lubrication of all moving parts in the Ruger Mark II and to prevent
|
|||
|
rust. Accumulation of CLP can attract particles of dust and dirt
|
|||
|
which can interfere with the safe and reliable function of the
|
|||
|
pistol. Do not, therefore, apply excess CLP unless storing the
|
|||
|
weapon for an extended period of time. If storing the weapon and
|
|||
|
using a heavy coating of CLP, the weapon should be disassembled and
|
|||
|
re-cleaned and lubricated with a light coating of CLP before
|
|||
|
firing.
|
|||
|
|
|||
|
- STORAGE WARNING -
|
|||
|
|
|||
|
If the pistol has been stored, before firing it again, completely
|
|||
|
disassemble it as detailed elsewhere in this manual, remove all
|
|||
|
grease and lubricant, apply a light coating of CLP to all parts as
|
|||
|
described in the section on cleaning and be sure to run a dry patch
|
|||
|
through the barrel after cleaning with a bore brush soaked in CLP.
|
|||
|
Do not keep the pistol stored in a leather holster or leather case.
|
|||
|
Leather attracts moisture, even though the holster or case may
|
|||
|
appear to be perfectly dry. Never store the Mark II pistol in such
|
|||
|
a manner as it may be dislodged. Always store the Mark II securely
|
|||
|
and unloaded.
|
|||
|
|
|||
|
|
|||
|
- LUBRICATION WARNING -
|
|||
|
|
|||
|
Firing the pistol with oil, grease or any other material even
|
|||
|
partially obstructing the barrel may result in damage to the pistol
|
|||
|
and death or injury to the user and those persons nearby. Never
|
|||
|
spray or apply any lubricants directly to the ammunition. If the
|
|||
|
powder charge of a cartridge is affected by the lubricant, it is
|
|||
|
possible that the charge will not ignite but the energy from the
|
|||
|
primer in the cartridge case may be sufficient to push the bullet
|
|||
|
into the barrel where it may be lodged. Firing a subsequent bullet
|
|||
|
into the obstructed barrel may damage the pistol and cause death
|
|||
|
or injury to the user and persons nearby. Use all lubricants
|
|||
|
properly and according to the lubricant manufacturer's suggestions
|
|||
|
and recommendations.

Reassembling the Ruger Mark II
|
|||
|
|
|||
|
|
|||
|
ASSEMBLY OF THE MAGAZINE
|
|||
|
Assemble the magazine in the reverse order of its disassembly,
|
|||
|
being especially careful to contain the spring and plunger as the
|
|||
|
base is being locked into place. After assembly of the magazine,
|
|||
|
test the follower to ensure that it has free movement.
|
|||
|
|
|||
|
ASSEMBLY OF THE BOLT
|
|||
|
The bolt is assembled in the reverse order of its disassembly.
|
|||
|
When installing the firing pin spring, make certain that the front
|
|||
|
of the support curves DOWN into the bolt. After assembly, test the
|
|||
|
extractor and firing pin for free movement. Put the recoil spring
|
|||
|
assembly back into the bolt.
|
|||
|
|
|||
|
INSTALLATION OF THE UPPER RECEIVER ASSEMBLY
|
|||
|
Grasp the lower receiver in a natural shooting position. Point
|
|||
|
the pistol upward vertically and pull the trigger to pivot the
|
|||
|
hammer backward to a cocked position. Lower the pistol to a
|
|||
|
horizontal position. Place the upper receiver about <20>" ahead of
|
|||
|
its final position and press it backward and downward so that the
|
|||
|
trigger guard lug engages the front recess on the bottom of the
|
|||
|
upper receiver. The upper receiver is properly aligned when the
|
|||
|
rear end of the upper receiver is approximately even with the rear
|
|||
|
end of the lower receiver. If proper alignment is not achieved by
|
|||
|
mere hand pressure then it is necessary to strike the muzzle with
|
|||
|
a plastic, rubber or wooden hammer. Inspect the inside of the
|
|||
|
receiver to see if the hammer is up. If the hammer is up, the bolt
|
|||
|
will not go into the receiver. If the hammer is up, point the
|
|||
|
pistol up vertically and pull the trigger to make the hammer go to
|
|||
|
the cocked position and ensure that the hammer strut is free.
|
|||
|
|
|||
|
INSTALLATION OF THE BOLT ASSEMBLY INTO THE RECEIVER
|
|||
|
With the muzzle still pointing slightly upward, insert the
|
|||
|
bolt into the receiver SPRING SIDE UP. If you put it straight in,
|
|||
|
the bolt will easily slide right into the receiver.
|
|||
|
|
|||
|
- FIRING PIN STOP WARNING -
|
|||
|
|
|||
|
When sliding the bolt assembly into the receiver, be certain that
|
|||
|
the firing pin stop is in the bolt. If the bolt is assembled
|
|||
|
without the firing pin stop in place, the first time the Mark II
|
|||
|
pistol is dry fired (no live cartridge in the chamber), the firing
|
|||
|
pin will be free to move forward to the extent that it will dent
|
|||
|
the rear face of the chamber, thus rendering the upper receiver
|
|||
|
useless and beyond repair.
|
|||
|
|
|||
|
INSTALLATION OF THE MAINSPRING HOUSING ASSEMBLY
|
|||
|
Point the empty pistol downward and pull the trigger until the
|
|||
|
hammer falls forward to its vertical (fired) position. Grasp the
|
|||
|
mainspring housing and insert the mainspring housing into the
|
|||
|
receiver by positioning the mainspring housing pin into the bottom
|
|||
|
of the hole in the lower receiver and push it straight up through
|
|||
|
the hole in the upper receiver. As the mainspring housing pin is
|
|||
|
pushed upward through the receivers, it passes through the slot in
|
|||
|
the bolt and also passes by the rear end of the recoil spring
|
|||
|
guide, camming the recoil spring guide forward to put initial
|
|||
|
tension into the recoil spring. Continue pressing the mainspring
|
|||
|
housing pin upward through the receivers until the mainspring
|
|||
|
housing pin protrudes about 1/8 inch above the top of the upper
|
|||
|
receiver. During this step, be certain that the rear of the bolt
|
|||
|
is flush with the rear of the receiver and that the hammer is in
|
|||
|
its fired (forward) position. When the hammer is in the forward
|
|||
|
position, it is then possible to observe the hammer strut. The
|
|||
|
mainspring housing pin will snap into place when it has traveled
|
|||
|
to its correct position.
|
|||
|
|
|||
|
VERIFY THAT THE HAMMER IS AGAIN FORWARD
|
|||
|
Point the empty pistol down towards the floor and pull the
|
|||
|
trigger. This will cause the hammer to fall forward. Release the
|
|||
|
trigger and do not touch it again!
|
|||
|
|
|||
|
REPOSITION THE HAMMER STRUT
|
|||
|
Point the MARK II straight up until you hear the hammer strut
|
|||
|
fall back with a slight click. You will have to raise the pistol
|
|||
|
rapidly to cause the hammer strut to fall back. Do not pull the
|
|||
|
trigger. Keep the Mark II pointing upward.
|
|||
|
|
|||
|
LATCHING THE MAINSPRING HOUSING
|
|||
|
The mainspring housing is now ready to be swung shut but it
|
|||
|
is essential that the hammer strut comes to rest on the mainspring
|
|||
|
plunger as the housing is closed. The mainspring plunger lies
|
|||
|
inside the mainspring housing and may be seen through the slot in
|
|||
|
the upper end of the housing. If the hammer strut does not contact
|
|||
|
the mainspring plunger as the housing is swung shut, it will either
|
|||
|
be impossible to complete the closure of the housing or the housing
|
|||
|
may be closed but it will be impossible to draw the bolt all the
|
|||
|
way back. It is also essential that the hammer itself be in its
|
|||
|
uncocked forward position (resting against the firing pin) as the
|
|||
|
mainspring housing is swung shut. With the MARK II still pointing
|
|||
|
up vertically and tilted at a slight angle to cause the hammer
|
|||
|
strut to drop into the correct position to meet the mainspring
|
|||
|
plunger in the mainspring housing, close and latch the mainspring
|
|||
|
housing by pushing the latch into its original position with the
|
|||
|
heel of your hand.
|
|||
|
|
|||
|
TESTING FOR PROPER ENGAGEMENT
|
|||
|
When proper engagement is achieved, closure is complete
|
|||
|
against the tension of the mainspring, which can be felt as the
|
|||
|
mainspring housing is pushed into the recess in the back strap. To
|
|||
|
find out if you did everything correctly, grasp the bolt ears and
|
|||
|
pull the bolt back. If the bolt comes all the way back, you
|
|||
|
reassembled the Ruger Mark II correctly. If the bolt fails to come
|
|||
|
back, it is because the hammer strut is improperly positioned. If
|
|||
|
the hammer strut is improperly positioned, then open the mainspring
|
|||
|
housing again and go back to the step entitled VERIFY THAT THE
|
|||
|
HAMMER IS AGAIN FORWARD.
|
|||
|
|
|||
|
- USE OF FORCE CAUTION -
|
|||
|
|
|||
|
It isn't the amount of force that does the job but how that force
|
|||
|
is applied. If all else fails, bring the pistol into Combat Arms
|
|||
|
and we'll show you how to do it at no charge if you purchased the
|
|||
|
Mark II here. Otherwise there is a $5.00 fee. Everyone agrees that
|
|||
|
the Ruger factory manual for the Mark II pistol leaves a lot to be
|
|||
|
desired. Sorry, but the only thing that will change that is if you,
|
|||
|
the consumer, write to Sturm, Ruger & Company, Inc. and complain.
|
|||
|
Combat Arms has spare factory manuals if you need one ($1.00).
|
|||
|
|
|||
|
- RECALL NOTICE -
|
|||
|
|
|||
|
If your serial number is 210-92816 to 210-94772 or 211-28500 to
|
|||
|
211-40000, Sturm, Ruger & Co. Inc. advises that two (2) pistols in
|
|||
|
the aforementioned serial number range have been discovered to fire
|
|||
|
if the trigger is pulled when the safety is on S and then the
|
|||
|
safety is moved to the F position. If, with an empty pistol, you
|
|||
|
cock the pistol, put the safety to S and pull the trigger and then
|
|||
|
put the safety to F and pull the trigger, you should hear a click
|
|||
|
as the hammer falls in a properly functioning pistol. If you do NOT
|
|||
|
hear the click, the pistol can fire simply by moving the safety to
|
|||
|
the F position. Do not use the pistol if it does this! Ship it at
|
|||
|
once via UPS to Sturm, Ruger & Co. Inc., Dept. MKII, Lacey Place,
|
|||
|
Southport, CT 06490. If you prefer, Combat Arms can insure and ship
|
|||
|
the weapon for you for $10.00. Ruger will repair the pistol without
|
|||
|
charge to you.
