The Magpul MOE SL Handguard for the HK SP89 and MP5K (brand part number MAG1048-BLK) is a black, high-strength injection-molded polymer handguard built to improve ergonomics and control on the SP89/MP5K and their clones with a 5-inch barrel. Magpul cuts M-LOK compatible slots at the 3, 6, and 9 o’clock positions for direct-attach lights and grips, and adds a large muzzle-end hand stop styled after the HK K-series handguard profile. A threaded fastener provides rigidity and stability without requiring a user-adjusted tensioning mechanism, simplifying installation and long-term fit. It’s a direct upgrade for SP89/MP5K owners who want better control and modern accessory compatibility in the compact K-series footprint.
