Polymer drop-in MP5 handguard with M-LOK slots and an integrated hand stop, no top rail.

The Magpul SL Hand Guard is the value M-LOK forend for the HK94, MP5, and their clones. It drops in as a direct replacement for the factory handguard, adds M-LOK slots at the 3, 6, and 9 o'clock positions, and molds in a hand stop up front to index the support hand and keep it behind the muzzle. Unlike the Midwest Industries aluminum handguard, it carries no top optic rail, so it pairs with the factory diopter drum sights or a receiver-mounted red dot rather than a rail-mounted optic.
Built from Magpul's reinforced polymer, it is lighter and far cheaper than aluminum MP5 handguards while still giving you a modern accessory interface for a light or a sling mount. As a US-made polymer part it also counts toward 922(r) compliance on imported MP5 clones, which matters when you are swapping foreign-made parts onto a build.
Fitment is the HK94/MP5 pattern with a standard 8-inch barrel and clones cut to the same profile. It does not fit the .22 LR MP5. If you want a top rail for a rail-mounted optic, step up to the Midwest Industries top-rail handguard instead.
Add the Magpul SL Hand Guard (HK94/MP5) to your build and see how it enhances your platform.
