Our Tikka T3x Picatinny style scope mounts are proudly made in America to exacting tolerances. Precision machined in 17-4 stainless steel, and finished in either Black Cerakote, or a natural silver "Bead Blasted" finish. We strictly hold these mounts to tighter tolerances than allowed under the Picatinny standard (MIL-STD-1913), ensuring complete compatibility with all Picatinny style, as well as Weaver style scope rings. ** Each base ships with a 6mm recoil pin, two 3mm alignment pins, #6-48 alloy steel Torx screws, and a T15 Torx wrench.
