The Sidelok is a revolutionary new mounting system for optics. The patented cam system locks the mount down onto picatinny without the need of tools, side levers, or huge knobs. The release system allows users to change out their optics on the fly with less hassle. The 2 levels of locks (Micro Mount Specific) ensure the optic will not move unintentionally, maintaining zero for the shooter, and returning to zero when remounting in same position after removal. This mount utilizes an absolute co-witness.
