The Sidelok RMR Mount, a groundbreaking innovation that redefines how you attach and utilize your red dot optic. True Quick Detach (QD) Functionality: Say goodbye to cumbersome tools, levers, and knobs. The Sidelok system features a simple push-button design that allows you to securely mount and detach your RMR in seconds, without compromising zero. The Sidelok system locks your RMR onto your Picatinny rail with unwavering stability, ensuring that your optic remains securely in place, even during intense recoil or jarring movements. The Sidelok system guarantees to maintain zero and ensures a continuous return to zero when remounted in the same position. This eliminates the need for re-zeroing after detaching and reattaching your RMR, saving you valuable time and effort. The Sidelok RMR Mount provides an absolute co-witness, allowing you to seamlessly transition between your red dot sight and your iron sights without any height adjustment. This ensures rapid target acquisition and enhances situational awareness in any situation. Beyond the Trijicon RMR, this mount is compatible with a wide range of red dot optics with similar footprints, including the Trijicon SRO, Holosun 407c/507c/508T series, Riton X3 Tactix PRD, Swampfox Kingslayer/Liberty/Justice, and more.
