Heckler and Koch (HK USA) Folding Stock Sp5k Black

Overview

The Heckler and Koch Folding Stock for the SP5K is a purpose-built collapsible buttstock designed for the HK SP5K platform, serving operators, law enforcement, and civilian shooters who require compact handling without sacrificing ergonomic control. Engineered to German manufacturing standards, this folding stock integrates seamlessly with the SP5K receiver and locking mechanism to ensure secure, repeatable positioning. It features a lightweight design—weighing just 0.75 lbs—and a black hard-anodized finish that provides corrosion resistance and reduces light reflection. The geometry maintains the proper grip angle and control layout while significantly reducing the overall package size for vehicle transport, close-quarters operations, or storage in confined spaces. This stock is compatible exclusively with the HK SP5K and direct-blowback 9mm variants, including the MP5K, MP5K-PDW, MP5K-N, and SP89. Installation requires no gunsmithing and bolts directly to the factory receiver using standard hardware.
