Tikkakoski was at first a metal workshop established in 1893 in Jyväskylä, Finland, which later, at the end of World War I in 1918 evolved into a factory that produced gun components. One of the most important guns of Tikka in the 20th century is most definitely Suomi KP/-31, which is regarded as one of the most successful submachine guns of World War II.
Tikkakoski and Sako cooperated on a prototype rifle series in 1981 and soon after that, Tikkakoski was acquired by Sako. By the end of the decade, the production of Tikka rifles has already shifted from Jyväskylä to Sako headquarters in Riihimäki. Tikka still holds on to their traditional gunsmith craftsmanship, visually inspecting every rifle barrel and then manually testing the rifle with test shots. In 2009 Beretta group took over Sako, which got Sako and Tikka access to the most advanced production methods.
In 1990 Tikka M558 replaced older model M55, which was produced until 1989. M558 was one of the first rifles manufactured in Sako headquarters in Riihimäki, where Tikka moved to after leaving Jyväskylä. M558 only uses 16.5 mm dovetail with a recoil notch for mounting purpose, because it lacks 4 tapped mounting holes compared to other Tikka rifles.
The main difference between the older M55/M65 rifles and the newer M558/M658 is the middle part of the dovetail, which got extended upwards, meaning the middle part of the receiver, where the cartridges are inserted and ejected is not completely open anymore and it can be seen that it even has a dovetail notch, which runs along the whole length on the left side, although that is still not enough to install mounts for dovetails on that part of the receiver.

M558 is chambered for:
It comes in 4 variants:
One piece mounts for some other Tikka rifles
which are meant to be installed on the 16,5 mm dovetail and make use of the recoil stopper will fit this rifle as well. Majority of these mounts will have T3/T3x in the name, as these two models are the most recent.
For fixed mounts on this rifle, we recommend Optilock Tikka Base mounting bases. We can insert rings onto these bases, but we must be careful, because Optilock rings are available only for 1inch (25.4mm), 30mm and 34mm diameter scope tubes. One special feature of the Optilock rings are the polymer inserts (except the 34mm ring, which does not include inserts), which prevent scratches on the scope. If we want to install scopes with rails or scopes with tube diameters other than these of Optilock rings, we need to reach for rings of other companies like Recknagel, EAW or Osuma, and they fit Optilock bases as well.

For Tikka M558 repeatable mounts, a pivot mount of MAK would be appropriate.
If you have this rifle or any other rifle at home, we would really appreciate it if you could send us some photos of the rifle receiver (mounting surface of the rifle when there are no mounts installed), because it would help us expand our rifle mounts database. If you send us a photo of rifle receiver which we don’t already have, that would be of great value to us and we will definitely reward you for your help.
