Noisefighters CliffhangIR-K Picatinny Optics Riser
PLEASE INQUIRE FOR CURRENT STOCK STATUS OR LEAD TIME PRIOR TO ORDERING
The Noisefighters CliffhangIR-K 0.83″ Rail Riser is a precision-machined, duty-grade rail riser designed to elevate red dot sights, multifunction aiming lasers, and clip-on thermal imagers to an optimized height on MIL-STD-1913 / Picatinny top rails. Its 0.83″ rise delivers an improved heads-up profile with reduced neck strain and enhanced compatibility with passive night vision aiming and larger hearing protection systems.
Constructed from a monolithic block of 7075-T6 aluminum with a black hardcoat anodized finish, the CliffhangIR-K delivers professional-grade durability while remaining rugged and lightweight at only 3.8 ounces. The extended 7.7″ length with 19 slots provides ample space for multiple devices, making it versatile for mounting optics and lasers in mission-oriented configurations.
Raising optics and lasers above handguard-mounted switches, buttons, and iron sights helps mitigate light splash and image shadowing while shifting center of gravity rearward for better balance on your platform. The riser’s design also supports compatibility with magnifier systems such as the Unity Tactical FAST FTC (flip-to-center) mount.
The CliffhangIR-K is compatible with MIL-STD-1913 / Picatinny top rails and is made in the USA, reflecting Noisefighters’ commitment to rugged quality for professional and enthusiast shooters alike.
