Kinetic Sidelok Trijicon MRO Mount | Lower 1/3 Co-Witness - Black SID5-220

The Kinetic Sidelok Trijicon MRO Mount (Lower 1/3 Co-Witness) provides a rock-solid, quick-detach (QD) solution for mounting optics to MIL-STD 1913 Picatinny rails. Traditional QD mounts often struggle with shifting zeros because their lever-tension systems can loosen or settle unevenly under heavy recoil. KDG solves this instability with its patented, tool-free cam-lock system. By mechanically indexing the optic into a repeatable position every time, the Sidelok eliminates the guesswork and hardware failure points common in older designs.

The true technical edge here is the removal of human error. Rather than relying on inconsistent manual torque or friction-based levers, the Sidelok utilizes a dual-locking cam interface. This mechanism applies the same clamping force every time it’s engaged. For the shooter, this means consistent alignment across thousands of rounds, significantly reducing point-of-impact shift and removing the need to constantly check or re-tighten your mounting hardware in the field.

Built from CNC-machined aircraft-grade aluminum, this mount creates a rigid, high-strength interface without the bulk. The 1.57-inch optic center height is specifically tuned for a lower 1/3 co-witness, keeping your primary sight picture clear while ensuring your backup iron sights remain accessible if needed. Weighing in at only 2.9 ounces, it adds minimal mass to your rifle, maintaining a fast-handling feel without sacrificing the structural integrity required to stand up to hard use.
