Sako and Tikka T3x rifles do not but we do recommend Sako Optilock for its great quality and value for money.
Tikka T3 rifles come with a set of Optilock 1” alloy rings that suit a scope of up to 40mm objective lens size. An exception for this is the Tactical, Super Varmint and CTR models as they come standard with Picatinny rails. Battue models are also not sold with rings included as generally they are purchased for use with open sights only.
