Not stainless but for Tikka-

Not sure if the Picatinny for the Tikka T3 Tactical fits or not.
The Tactical has the standard T3 groove underneath so if the T3
is drilled and tapped, the same mount probably fits. I would check
to see if Tikka sells the rail. You can always have it matte hardchromed
if you want a stainless look.
