Optilocks on a Tikka are completely pointless.
Use the top rail, only mount that really does this is the Spuhr direct mount, which saldy does not work with the original T3 on long action rounds, just T3x.
Optilocks in general are over-priced junk, screws are poor quality, unlike the original pre-Beretta Sako rings which were ace, windage adjustable and quick detach to boot.
The Beretta group reliased it was better to sell people both rings and bases. The ringmounts, while better, are over priced to the extreme.
