5KU SS-8 Folding Stock
Looking for a lightweight and solid folding stock that mounts directly to a RIS (1913) stock interface and allows folding to either side for easy handling or storage? Need a QD sling mount for quick sling attachment? The SS-8 stock offers excellent strength, stability, and comfort thanks to its straight skeleton design with a wide buttplate. Its CNC-machined aluminum body ensures low weight and high durability, while the steel mounting base provides secure attachment to any 1913 rail. The ambidextrous folding system allows right- or left-side folding, making it perfect for shooters of all preferences. A built-in QD socket provides a solid sling mounting point, and installation is fast and reliable. The SS-8 is compatible with 5KU RIS adapters for M4, MP5, and AK platforms, making it a versatile choice for custom airsoft builds.
