Sako 100 Optilock Base S5100212099

The Sako 100 Optilock Base is an authentic, premium factory-original optics foundation engineered explicitly to coordinate with the Sako 100 switch-caliber rifle system. Precision-machined from high-strength solid steel, this rigid mounting rail features an elite weather-resistant Cerakote coating that beautifully mirrors the technical finish of factory barrels. Unlike traditional standard receiver mounts, this specialized single-piece base fastens directly over the integrated barrel extension indexing tracks to ensure that absolute optical zero is safely maintained during rapid barrel and caliber exchanges. The interface serves as a stable mounting baseline that accepts all standard heights and tube diameters of proprietary Sako Optilock split scope rings. Equipping your premium takedown rifle with this genuine factory-specified accessory ensures rigorous structural alignment, eliminating physical stress on high-magnification glass while safeguarding sub-MOA field tracking.
