GENERAL INFORMATION

The MLR-1722 rifle is an autoloading rifle cham­bered for either 22 Long Rifle or 17 Mach-2, and so
marked on the barrel. It is recoil operated and uses
a standard 10 shot Ruger rotary magazine. Pulling
back the bolt handle cocks the internal hammer
and compresses a coil spring. When the bolt is
released, it moves forward by itself and forces a car­tridge from the magazine and directs the cartridge
into the chamber of the barrel. The bolt is held
against the chambered cartridge by the force of the
recoil spring.

When the trigger is pulled, the hammer is released
and strikes the firing pin. The firing pin in return
strikes the rim of the cartridge causing an indent on
the case. This indent causes the internal priming
mixture to ignite and a large amount of expanding
gas is instantly generated which acts on the interior
of the cartridge case in all directions.

Because the bullet offers the least path of resistance
it is forced out of the case and exits the muzzle of
the barrel. The bolt then moves rearward by itself
extracting and ejecting the fired case, at the same
time it re-cocks the hammer, compresses the recoil
spring as mentioned earlier and feeds a new
cartridge into the chamber upon closing. Once the
trigger is released the rifle is ready to fire again.

Each time the rifle’s trigger is pulled and released
the same cycle is repeated until there is no more
ammunition left in the magazine or chamber.

WARNING: THE RIFLE WILL FIRE IF THERE IS
A CARTRIDGE IN THE CHAMBER OF THE BAR­REL EVEN IF THERE IS NOT A MAGAZINE IN
THE RIFLE! REMOVING THE MAGAZINE DOES
NOT UNLOAD THE RIFLE. ALWAYS INSPECT
THE CHAMBER AND MAGAZINE EACH TIME
THE RIFLE IS HANDLED TO BE CERTAIN
THERE ARE NO CARTRIDGES IN EITHER.

OPERATION SAFETY

The MLR-1722 has a cross-button safety that is
located in the front of the trigger guard. It can only
be operated when the hammer is cocked.

The safety is “ON” when it protrudes from the right
or bolt handle side of the rifle’s trigger guard assem­bly. In this position the safety blocks the sear of the
rifle and the rifle cannot be fired from a normal pull
on the trigger.

NOTE; THE SAFETY SHOULD ALWAYS BE IN
THE “ON” POSITION WHEN THE RIFLE IS NOT
BEING FIRED.

The safety is “off” when it protrudes from the left
side of the trigger guard assembly. When the safety
is off a red band on the safety itself will be visible.
DO NOT RELY ON THE APPEARANCE OF THE RED
BAND TO INDICATE THAT THE SAFETY IS OFF. If the
rifle is dirty or if the available lighting is poor the red
band may not be visible. IF THE SAFETY IS “OFF”
AND THE TRIGGER IS PULLED THE RIFLE WILL FIRE.

The safety itself is held in position by a plunger that
is pushed upwards by a coil spring. When the safe­ty is moved to either the “on” or “off” position a
clear “click “ should be heard. Frequently check the
position of the safety to always be certain it has not
been inadvertently been moved. If the safety moves
to easily or does not make an audible “click “ when
being used STOP using the rifle immediately and
return prepaid to:

WARNING

The only “safe “ rifle is one that the bolt is open,
chamber is empty and magazine is removed from
the gun. Never allow the rifle to be used in a
careless manner or to be pointed in an unsafe
direction.
