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.
