Kdg Sidelok Mro Mount Lwr 1/3 Co

The Kinetic Development Group Sidelok MRO Mount Lower 1/3 Co-Witness is a purpose-built quick-detach optics mount system engineered for shooters who demand fast sight changes without tools or accessories. Unlike traditional picatinny mounts that require Allen wrenches or lever manipulation, the Sidelok delivers tool-free installation and removal through its proprietary cam-lock mechanism, enabling operators to swap optics between platforms in seconds during training transitions or duty rotation changes.

The mount's dual-locking system ensures zero retention through repeated cycles—critical for shooters who frequently remove and reinstall the same optic. The lower 1/3 co-witness sight picture positions your backup iron sights in the lower third of the MRO's viewing window, maintaining a clear optical path while preserving sightline reference for fast target acquisition or emergency fallback. At 0.31 lbs, the mount adds minimal weight to your upper receiver while maintaining the rigidity required to hold zero under recoil impulse. The compact 4.25-inch profile minimizes rail real estate consumption, leaving room for forward-mounted lights, lasers, or additional accessories on modern fighting rifles and carbines.

This mount suits operators running the Trijicon MRO as a primary optic across training environments, duty carbines, and reconfigurable AR platforms. The Sidelok system is favored by law enforcement instructors, military support personnel, and serious civilian shooters who value optic modularity and speed of changeover. Its no-tool operation eliminates the friction of gear-swapping workflows, making it particularly valuable in multi-rifle arsenals or when optics rotate between different mounting systems.
