Kinetic Development Group's latest addition to its SideLok family of mounts is the new Trijicon MRO mount. The patented cam system locks the mount down onto a Picatinny rail without the need of tools, side levers, or huge knobs. The release system allows users to easily change out their optics. The two levels of locks (MRO Mount) keeps the optic from moving unintentionally, maintaining zero for the shooter, and returning to absolute zero when remounting in the same position after removal. This lightweight mount utilizes a lower 1/3 co-witness.
