GENERAL INFORMATION
The MLR-1722M rifle is a semi-autoloading rifle chambered for either 17HMR or 22Win Mag, and so marked
on the barrel. It is recoil gas operated and uses a standard 9 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.
This rifle has a gas dispersion block attached to the bottom of the barrel. A very small orifice hole allows a small
amount of expanding gas to be released from the barrel
and dispersed through the gas dispersion block.
DO NOT REMOVE THIS BLOCK OR REPLACE THE
BARREL ON THIS RIFLE, AS IT WOULD CAUSE AN
UN-SAFE CONDITION.
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.
