Integral Scope - Unlike the screw-on aluminum “tip-off” scope mount

Mount Bases base furnished with standard Ruger 10/22 rifles, the

Ruger 10/22 Magnum features steel scope bases

integral to the receiver, which accept the patented

Ruger scope rings (furnished at no extra charge).

Bolt - The Ruger 10/22 Magnum bolt is manufactured from

a dense tungsten alloy, in order to give the bolt ade-

quate mass required to function correctly with the

more powerful .22 Winchester Magnum Rimfire car-

tridge.

The RUGER

MODEL 10/22

MAGNUM is an autoloading rifle cham-

bered for the .22 Winchester Magnum Rimfire cartridge. It is recoil (“blowback”)

operated and uses a 9-shot rotary magazine. Retracting the bolt handle cocks the

internal hammer and compresses the recoil spring. When the bolt is manually

released, it moves forward (driven by the recoil spring), strips a cartridge from

the magazine, if a loaded magazine is in place, and chambers the cartridge. The

bolt is held against the chambered cartridge by the recoil spring.

When the trigger is pulled, the hammer is released and strikes the firing pin.

The firing pin indents the cartridge case rim and ignites the priming compound

inside the rim. This ignites the powder in the cartridge case and a great volume

of gas is instantly generated, which acts on the interior of the cartridge case in

all directions.

Because the bullet offers the least resistance, it moves out of the cartridge case

and exits the muzzle. The bolt then moves rearward automatically, extracting

and ejecting the fired cartridge case, and at the same time cocking the hammer

and compressing the recoil spring, etc., as described above. Once the trigger is

released, the rifle is ready to fire again.

Each time the trigger is pulled and released, the same cycle is repeated until

there are no more cartridges in the magazine or in the chamber.

The rifle will fire if there is a cartridge in the chamber and the trigger is pulled,

whether or not there is a magazine in place! Removing the magazine does not

unload the rifle. Never assume the rifle is unloaded. Visually inspect the chamber

and the magazine each time the rifle is handled to be certain there are no car-

tridges in either.
