The Kinetic Development Group Sidelok Aimpoint ACRO Mount is a professional-grade, quick-detach (QD) interface engineered for MIL-STD-1913 Picatinny rails. Designed to solve the common failure points of traditional threaded mounts—which often loosen under recoil or require tools for field adjustments—the Sidelok system replaces friction-based fasteners with a patented push-button cam lock. This ensures a rock-solid, tool-free attachment that provides consistent clamping force every time.
The core technical advantage is the shift from user-applied torque to controlled mechanical engagement. By utilizing a spring-loaded cam with a two-stage safety, the mount applies repeatable tension across varying rail tolerances. This eliminates the guesswork of over- or under-tightening, guaranteeing a true return-to-zero. Whether you are running an Aimpoint ACRO P-2 or a Steiner MPS, this system provides the reliability needed for modular rifle configurations.
At a precise absolute co-witness height, this mount places your optical center 0.4 inches above the rail for seamless alignment with standard iron sights. CNC-machined from 6061-T6 aluminum and finished with a Type III hardcoat anodizing, the SID5-125 is built to endure heavy recoil cycles and harsh field handling without adding unnecessary weight.
Key Features
- Push-button cam system + spring-loaded tension control = consistent lockup without tools
