The Aim Sports Extended M-LOK Handguard for the HK91 and G3 platforms (brand part number MMH94) replaces the factory forend with a CNC-machined 6061-T6 aluminum handguard built around the Magpul M-LOK mounting system. It’s engineered to work with modern and traditional shooting techniques alike, giving HK91/G3-pattern rifles the same accessory-mounting flexibility found on modern AR builds. The handguard ships with two modular top sections, one Picatinny and one M-LOK, so shooters can configure the top rail to match their optic or sight setup. U.S.-made mounting hardware backs up the solid, CNC-machined construction. Finished in black hard-coat anodizing, this extended-length model is a straightforward upgrade for any HK91/G3-pattern rifle that needs modern rail real estate.
