Modernize your AK platform with the unmistakable angular and "skeleton" design of the KPYK (КРУК) handguard. This 5KU replica is made entirely of high-quality aluminum, CNC machined to ensure maximum lightness without sacrificing robustness. It is the perfect solution for those looking for a modern "Spetsnaz" aesthetic and improved ergonomics.
Unlike the short version, this "Medium" model features an extended gas tube cover that wraps around the gas block, providing an uninterrupted upper Picatinny rail (ideal for optics) and additional side M-LOK slots. The lower handguard offers ample M-LOK slots at 3, 6 and 9 o'clock. A detail of realism is the ability to maintain the original cleaning rod.
WARNING: COMPATIBILITY
This kit is designed for AEG replicas of the CYMA AKM, AK74S, AK105 series and other clones with similar specifications. Installation, although "drop-in", may require technical knowledge and minimal adjustments depending on the replica manufacturer.
