Optimize your S20 Rifle with Sako’s ONE Optilock 20MOA Picatinny Scope Mount. Precision machined from premium aluminum and steel, this optics mount is both low profile and lightweight and features two robust attachment points for installing on a Weaver/Picatinny rail. The ONE Optilock Mount allows the shooter to attach the Optilock rings at multiple locations on the mount to accommodate a wide array of rifle scopes to be mounted, and a 20 MOA inclination increases the optic’s adjustment range.
