The Sako L579 -rifle was designed by Eino Mäkinen at the Sako factory in 1958 on basis of the previous Sako L57 -rifle.
The new hunting rifle was designed in such a way that in it could be used as much as possible the precision casting parts
of a new precision casting foundry. The weapon was originally named Sako L579, but later the word “forester” was included
to the name.
There are four versions of the Sako L579 Forester's rifle, Standard, Deluxe, Heavy-Barrel and Mannlicher -carbine stock model.
The weapons were manufactured in following calibers: .22-250, .243 Win, .308 Win and 7mm-08. Heavy-Barrel version was 500 grams
heavier than other models (total weight 3.8 kg). The rifle was also produced a Sako L579 "Mannlicher" model, caliber .308 Win,
this had carbine model stock.
In 1984, the entire Sako rifle collection was renewed and the following models were available with the Sako L579 lock bolt:
Hunter, Deluxe, Super Deluxe, Carbine, Varmint, Classic and Target.
The barrel is made of a cold-forged from the high-quality Swedish Bofors steel. The surface of the barrel is oxidized. The barrel has
six right-handed rifling bars, the rise of the rifling varies by the caliber. Bofors Steel was used at least in the barrels produced
between 1968 and 1985. The receiver frame is made of forged, surface-hardened tempered steel and has been driven into its dimensions
by automatic machine tools. The bolt and bolt handle have been forged from one piece. The bolt is extremely durable and has been
tested with a pressure test load of eight tons.
Rifle stock with pistol handle is made of walnut wood and its surface treatment was either oil or lacquer (models Hunter,
Deluxe and Super Deluxe).
The receiver bridge has a, so called salmon tail, wedge-shaped rail for rifle scope mounts. The Sako rifle bolt is further developed
tube bolt from the Mauser bolt.
The weapons safety lever is positioned on the right side of the weapon. The loaded weapon is safe and the bolt is locked when the safety
lever has been turned to the rear position. When the safety lever is pushed into the front position, the bolt is released and the red
marker is visible under the safety lever. The red marker indicates that gun is ready for shooting.
The trigger assembly mechanism is wedge threshold firing device with a vertically falling sear. Trigger has no first pull (single stage
trigger pull). Both the sear engagement and after pull are adjustable. The trigger assembly is the same as for the Sako L461 and L61R
rifles. The trigger assembly is adjusted at the factory to approximately 2 kg. It is possible to adjust the Trigger pull by turning the
adjusting screw, but for safety reasons no less than 1.5 kg. Also the trigger after pull movement is adjustable.

adjustment, C = Trigger assembly attachment screw with locking screw.

Sako manufactured for the L579 -rifles a detachable clip magazine for the calibers .308 Win and .234 Win. However, the installation kit
does not fit directly into all Sako L579 -rifles, because during decades of production, small changes have been made to the weapon. In
the light of these changes, Sako L579 -rifles are divisible into four groups;
In weapons manufactured before 1970, the front end of the magazine is rectangular, a new trigger arch is required.
In weapons produced between 1969 and 1980, the front end of the magazine's baseplate is round and unsuitable for the detachable clip magazine, so the material should be removed and the trigger arch replaced.
In weapons manufactured in 1979 – 1981, the holder of the magazine's base plate is too long.
The series of weapons manufactured after 1982 is suitable for direct installation.
Sako L579 -rifles have been manufactured since 1957. By the year 1978 was manufactured about 132 000 rifles, of which about 32 000 rifles
were caliber .308 Win. The gun production continued until 1992.
In addition, the model Sako A II/L 579, with calibers .22-250 Rem, .243 Win, 7mm-08 Rem and .308 Win were manufactured between 1979 and 1980.
The weapon has a Sako’s so-called medium-length bolt action device.
The serial number of the weapon starts from the year 1957, serial No. 1. In 1974, the serial number 115033 was completed and from now on the
serial numbers 300000 was always up to the number 499999 were reserved. However, between 1991 and 1992 there are serial numbers outside of the
reserved serial number range, series 800000.
