Scope mounts for Tikka M658

About the company

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.

About the rifle

In 1990 Tikka M658 replaced older model M65, which was last produced in 1989. Exactly at that time Tikka moved from Jyväskylä to Sako headquarters in Riihimäki, which means the M658 was one of the first Tikka models manufactured in Riihimäki. It has a 16.5 mm dovetail along with a recoil notch on top of the receiver for mounting purpose.

The dovetail is partially disconnected, the middle part of the dovetail above the bolt only has a dovetail notch on one side, which means the insertion of cartridges directly into chamber is easier at the expense of possible worse shot accuracy in some cases because of less rigid rifle. Compared to similar Tikka rifles that came before and after M658, this one is an exception, as it doesn’t have 4 mounting holes.

Our recommendation for mounts

Fixed mounts:

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.

Detachable repeatable mounts:

For Tikka M658 repeatable mounts, a pivot mount of MAK would be appropriate.

Help us build our riflescope mounts database

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.
