The Magpul SL polymer handguard for HK MP5, SP5, and HK94 rifles upgrades the platform with modern ergonomics and accessory-mounting capability while preserving the classic lines that define these platforms. This drop-in 8-inch handguard replaces the factory forend without permanent modification, making it an ideal choice for shooters who want to add rails and grips to their HK without committing to a full rail system or altering the rifle's profile.

Built from high-strength, injection-molded polymer, the SL handguard features aggressive anti-slip texturing for confident control in wet or gloved conditions. The small muzzle-end hand stop gives your support hand a natural stopping point and helps steady the rifle during precision work. M-LOK slots at the 3, 6, and 9 o'clock positions let you mount lights, lasers, vertical grips, and other modern accessories exactly where you need them—no gunsmith required.

Magpul backed the design with a corrosion-resistant, mil-spec manganese phosphate steel threaded fastener, so the handguard won't rattle loose or degrade with hard use. Drop-in installation means no special tools or gunsmithing; if your HK MP5, SP5, or HK94 clone accepts factory-profile handguards, this one will fit. As a bonus, the SL qualifies as one 922(r)-compliant component for imported HK94/MP5 builds.
